LCD/PLASMA REPAIR

<< < (2/2)

Hi, I agree with you that to make a diagnosis is difficult, and to make it incorrectly is a very expensive mistake. I think a lot of engineers are struggling and try to put customers off a repair by quoting high prices. I am sure we will all get better given time but as we all know customers are not a patient bunch. thanks for the input, Norman

Hi guys, I've been self employed for 28 years now and couldn't survive without my wife's income.
One piece of advice I would give out,is not to hand your UK tax return in too early. The tax inspectors
sit twiddling their thumbs till some mug hands a return in early and off they go,investigating your
life.
One common fault not mentioned a lot is the lvds plugs/sockets with poor connections or the cable being too tight. With any picture fault on a lcd I remove them,scrape the pins and oil with WD40 before scrapping.Remember, most are glued at the screen end where I slice along the joint with a stanley knife
because the plug can fall apart (I've got the tshirt on that blunder from two years ago).
The price of lcd tv's are falling ,just the way it was before with cheaper crt tv's and customers are reluctant to shell out much for repairs as well. I'm thinking of changing my business name to 'Bob A Job
Week' as in the old Boy Scouts charrity,I might get more work.

bfn  tv john.

I am a retired electronics Engineer and have two friends who have made their livings in their
own service shops. As a challenge I have spent a bit of time repairing some of their boards down to the component level and find the following.
1. Information and schematics are hard to get- especially PSU - purposely.
2. Some components have the ID's ground off.
3. Components are difficult to acquire when identified.
4. Components are of a transitory nature and become obsolete quickly (How many different transistors, FETs do we need?).
5. SMD technology limits repair involvment in the small workshop.
6. Nothing stays the same - new pcb runs etc (any expertise gained is obsolete in 12 months).
7. In developed western countries wages kill any extended or concerted effort at repair.


Basically all the above whether overtly or covertly propagates the throw-away after failure
mentality.
There is no intention of the manufacturer or importing retailer to support his product longer
than that required by warranty. I live in a shire that has roadside junk collections and my
observation 3 yrs ago (in the 'boom' years), saw all the large high quality TVs, Amps and
players that had lasted 10 years or more dumped and replaced with the Plasma's and surround
sound systems. Now I see them there after a couple of years. Earth eaters Eh?

We are all being shafted to a consumer mentality and unfortunately the electronics service
industry is doomed. My commiserations.

Hi folks,

  Have to observe that being in the trade since the 50's there have been some changes, but to keep viable (and still eating, however poorly) one has to move with it if one wants to stay with it.

  Some years ago, all of my other local repair chums who with VCRs for instance, replaced an idler when just the tyre would do the biz, found customers just wouldn't pay when new VCRs came down to twenty five pounds or so. Well my tyres were just pence, so a profit was still made.

  Currently LCD screens are fragile, and no-one reasonably repairs Plasma due to cost and non-availability of new parts, but local tips have heaps of them, generally thrown not too gently into re-cycling bins for some cool political reasons.

   Recycling folks generally feel that current EU directives, especially the way local 'Council Clipboard Chums' interpret them is mindless twaddle - ask some, they see the waste first-hand.

   Optomistically, in our trade 'till expiry - Chris.
