Hi guys. Not sure if correct place, but here goes.
About 3 years ago I started playing with LCD TVs as a bit of a diversion, mostly obtaining scrapped sets from our Amenity sites. I have four working sets here (one still an LED experiment when time and inclination return) but of the many I could not fix, or had damaged screens, I retained the panels.
However, the amenity sites now charge for any TVs deposited, and will not allow any to be taken away, so my source has dried up, and this was never an exercise in spending money, so time to get rid of all those panels. Obviously I could sneak them back into the amenity sites, or stick on Ebay, but maybe they could be useful to anybody here (UK only in practice). Obviously I would expect cost to be covered, and maybe a small donation, but this is not a get rich quick exercise. Probably best if I pack stuff and whoever wants them arranges collection. Of course anybody with a pal visiting here could just pick them up from me.
Here is what I (think) I have:--
Sharp LC26AD5E. Various, but MAIN is faulty.
Sharp 26P70E. Main, Power, tuner and control.
Toshiba 23WL4G. Main (analogue only??)
JVC LT-26DR7SJ. Screen was dead, everything else was perfect.
Teknica. 3 panels. Some (marked) bits pinched of PSU.
TCM 27L66. Screen interface, inverter and PSU all believed OK.
Acer AT301W. No main board, everything else was OK. (I killed the mainboard trying to resolder an intermittent 30+way micro connector.
AOC L26W781B. 3 panels inc inverter. No main.
Samsung LE40R73BDR/XEW. Inverter, keyboard and screen interface.
Samsung LE40R74BD(R)S. X/XEU. All working panels.
Sharp LC37X20E217. Beleived all working.
Sharp LC-22SV2E. All panels believed working.
Samsung LE32B450C 4WXXU. Believed all panels OK, BUT I pinched a VDR from PSU (marked in red on panel)
Vistron 32”. Screen was NBG, so rest assumed OK.
Philips 32PF3320/10. Believed faulty screen and rest OK.
I prefer one job lot, but will do separately, but expect small donation on receipt.

Hi Les,

Have a very similar situation as chaps with White vans collect all flat screen and even tube tellies from local sites - Now mostly privately run for profit.

In the old days when they were council run, could grease the palm with a cheap repair or two, and bring home a dozen a week for spares/repair.

Eventually ended up with hundreds of not very useful panels - The ones that never go wrong or are a bit obsolete as used in Analogue stuff.

Also thought Fleabay, but can't be bothered with come-backs from folks who fit them upside down, and then want to talk about it.

Can't list here as there are hundreds, maybe thousands - haven't checked total lately, as prefer live a life of sorts, but if any Quuquer needs the odd obscure panel - can check in seconds, as every one listed, and tidily bagged up.

Mention as daughter is complaining about my likely future expiry, and the cost of the skips.

All the best Young Les - Chris.

I always tell my Radio Ham friends never clod anything out..... nuffin, not even duff fuses! Provided they weren't 'blackened', think of stand off insulators...!

I too a mass a lot of 'good parts' from owd tellies, I got drawer fulls of resistors, transistors and capacitors from clean boards all OK for experimenting,  speakers, coils and heat sinks.

Along came the modern telly:
The speakers are that diabolical I could make better ones out of a baked bean can, true, there's the odd transistor or two, coils,chokes and ally heatsinks, got boxes full of em they usually go like hot cakes at radio rallies.... and don't forget layers of mylar sheets and thick plastic from LCD screens.

Usually the case with me is if you 'clod' summat out you'll be wanting it the next day, as you know with modern tellys there's panels, panels and panels, when little ol' me needs one and I've never got the same..... or one that works.

All my scrapped telly's gets smashed up and put in the wheelie bin.... had as many as three CRT types in, 32" and a couple of 28" - surprising what a lump hammer can do innit? On a Tuesday we just listen for a load of puffing and panting and a load of glass tinkling, "ah, that will be the dustbin man, bring the dustbin in sweetie pie", I've fixed one or two for these guys as well and usually very little wrong that a bit of metal glue won't cure.

Did I mention glue?
I worked for a local electronic firm that produced radio kits as well PA units and echo units, I did the telly audio servicing. Well,  one guy bought a radio kit and it wouldn't work, he meticulous assembled it all gluing all the parts in with that 'grey coloured glue' (forget the name) - I can see him now explaining to the boss he waited half an hour so to be sure for the glue to set on the connections.

I ended up repairing the devil and rebuilding it, it took forever getting all that stuff off - every sniffing sliver had to come off!

Do have a couple of more true stories to tell.... but dare I?

Hi Davy,

Wasn't it called 'liquid' or 'plastic solder' or some-such for mending pots. Recall buying a tube in my early constructing days. Could explain why nothing ever worked - Chris

Suggest more true stories, remember stuff in Radio Constructor where Smithy got enraged with his apprentice Dick for being totally bone headed - Those were the days of 'Great 208'

[Davy]

Turnip, that sounds like the stuff.
I remember buying some in my early days, can't recall what for but it wasn't for joining wire that's for sure, my first soldering iron was the..... poker  in the coal fire and a tin flux, crying out loud how dy'a think I built my one valve HAC receiver - poker and flux, long life tip there better than Antec irons it was, they never burned out I can tell ya!  

Yeah I liked "In Your Workshop", see this link http://vintageradio.me.uk/radconnav/iywindex.htm

Here in Ireland
We pay a tax on all electrical item purchased, to cover the cost of recycling them in a safe way
Like the UK, most of the recycling is run by private companies, and try to charge me when I
bring in scrap electrical items
These companies in Ireland get paid from the taxes collected on sales and should not be charging
a second time
I don't know what the system is in the UK, but I thought this was a EU wide System
Here is a link to some info

Right guys, I take it I must scrap it all, no use to anybody. OK then.
Leonard085, I am on the Isle of Man, where we do thinks (sort of) our own way. We are NOT members of the EU, but because of ties and agreements with the UK, we tend to copy UK/EU rules on many things. Our amenity sites are part Gov, part local authority, and I think one is private. The best one, we knew it as "Harrods" was local authority run. Two old guys were there, and ran it well. Scrap metal went in skips, electrical stuff in "the end shed" where there was a 13A socket we could use. You could take anything. Excellent service. One day there was a Rayuburn OF22 oil fired cooker in the skip. One of the guys helped me to get at it, removing both burners, control valve, doors and hotplate as spares for my own OF22.
Then the Gov took it over! A petition was raised before the "improvements" took place opposing it, but to no avail. Many thousands of £££s later, after being closed for months, it reopened with about six guys in there, the old two having been retired. Big crawler with four finger grapper, a little "Jeep" style thing, new office for the men, new sheds, but no power, and designed with "One Way" to throw in skips FIRST on the way in, encouraging everybody to junk stuff, rather than leave it for second users. Anything decent mysteriously seems to disappear into the office, nothing worthwhile ever being available to the general public. Big signs proclaim how much was "recycled" each month. I feel like replacing "Recycled" with "Scrapped". Reuse has certainly long since been stopped. The TVs were a case where at one centre, they used to scratch a big X on the screen, to ensure their uselessness, but if you got there in time, you could take stuff. Then the £8 charge to drop off a TV, with I think £25 for a freezer. They seem to have a few big CRT TVs behing locked doors in the rain, marked "Paid" on the screens, but no sign of any LCD jobs. I think if they look "possibles", they go into the office. It must cost between 5 and 10 time the money to operate it since the "improvements", the only satified people being the Government and 6 workmen.

Hi Young Les.

The lack of paragraphs gives trouble to older Quuq folks, me included - Guess your'e one of those youngsters with good eyesight - Chris.

[Davy]

@leonard085

We can just take any scrap to the  Local Corporation tip, in my area you can I can't speak for other councils, they have huge containers for various items  and there's a fenced off place with a shed, you often find duff tellies, fridges and washing machines, I've seen em' wrecking the bad ones just for the copper wire and aluminium.... and others they pile up gently, very gently!

That EU is a law unto itself, you can't do this er that, you can't clod this er that, I'm still not sure about what parts you are not supposed to 'bin'... apart from Nicad batteries.

Here, you can take rubbish to the tip yourself or give em' a tenner (£10) and they will come and collect whatever.

One guy I know brought a load of  CRT tellies to look at he bought from a guy in a huge 'white van', when he told me where he got them from, I whipped the back of a couple before he could unload some - "no thanks don't bother, leave em on  ya van", paid over a grand he did they were all nicely wrapped and looked spanking new....   some of em had no chassis or parts missing.

Turnip (Chris), sorry about that. I had a bit of trouble with tinternet, so I actually wrote it in my word processor, then jusy copy/paste across. I am certain it had paragraphs there in abundance, but obviously formatting lost in transfer, and I never noticed.
Of course you can wear glasses like me (and most here?). And you will likely have a bench magnifier, stick that in front of the screen.
Cheers, Very Old Les.

[Turnip]

Hi Davy,
Met those shrink wrapped tellies, mostly with an 'Instruction Book' consisting of one page of nothing some years ago.

White van arrived at sites, and folks would kill for bargains where they mostly didn't go or were incomplete.

Thanks Les, but have noticed that some Quuq folks feel that 'old' is old. Mentioned my age to a certain Quuq Hero in passing and he was shocked that I would want to still try mend, what with my pensions and a heating allowance.

Find that after a life of trying mend things, don't want to stop 'till can't find my way back from the supermarket, and even then - Chris.

[OldLes]

Chris, I don't know if I win on bragging rights, only being 73, but if I can still ride my motorbikes (and I can and do), then I am sure I can exercise my brain on a TV. I no longer work on anything for money (but will sell stuff if I can), so if anybody wants a favour, it boils down to do I like them or not. If not, no chance!
Friday afternoon I was trying to check the ignition pickups on my Cagiva using a little Tek 212 'scope. Problems with triggering, plus difficulty in keeping the engine from racing or stopping (the problem), so taking screen shots at the same time required an impossible 6 hands. I will get my HP mains battery 1703 storage scope on it next when I have fitted some new "cobbled up" batteries. (wrong physical size).
Spent the last week sorting through my 500-600 valves. Many TV, many general purpose and scope valves. Like the panels, many will go to scrap, but I have quite a few ECC83s, which I understand the audiophools pay a lot for, so it will be off to Ebay with those. Nearly finished my database of them. No rest for the wicked, but it is that that keeps us old'uns young!
Les.

[Turnip]

Hi Old Les,

Guess you do, being only a young 72 myself but gave up my motorbikes some years ago, as but for a few days in the year they are cold and wobbly, and formerly used them mostly for late in life romance with the usual chocolates.

Used to have oodles of valves then met folks at recycling/social sites who thought they might make a pound on the Flea.

Realised that only audio stuff makes anything so handed over all my EF50s and valve telly stuff, some several boxes - No ECC83s though, as natch hadn't any.

Think have pair of PX4s somewhere after trying construct an audio amp with an efficiency of more than 5% - Couldn't of course, with 500v HT and a grid drive of at least 100v, got 5 clean Watts out of a pair. Was trying match with a couple of EL84s for stereo in a 50s RGD radiogram update.

Total failure of course, so recycled - esp as box had woodworm - Chris.

[OldLes]

Ah, but I do have some ECC83s! New and used, and I have a Telequipment CT71 curve tracer, and with an external 6.3 volts, I can test all those double triodes. I hope my prospective customers will value a phot of charcteristic curves, and pay for that privelidge. They may even get matched pairs at extra cost.
I have ECC81, 82, 83 and 88s. May just realise a few bob.
Wouldn't a few PL509s have given a good clean and powerful audio amp?
Not into circuit design myself, sometimes I barely understand simple circuits, but usually muddle by.
Cheers, Les.

[Turnip]

Hi Les,
You're quite right - PL509s would have done the biz, but not really 50s. Seem to recall making an amplifier using 6 x PL2509 in parallel push-pull with a voltage doubler power supply giving some 600v supply and a likely output of a Kilowatt or two but didn't have a suitable output trannie above 30 Watts at the time - Fun though.

Thinking Scopes, got one of those Chinese LCD ones that do most everything, and for 50 Quid. Turned it on and found it quite wonderful, but haven't got around to using it as it's a bit complex.

Agree that design is a problem - when you've sorted everything you know, something always turns up to prove you know nothing - never deterred though, as might eventually win through - Chris.
