NEON C3298F LCD TV

[yellowpinky]

Hello Group,
This set is dead with the red standby light only.
The power supply (MLT868) produces 25v,12v,5,and 3v.
Are there any common faults with this tv.
The signals board is CV109H and I think the eeprom is U6 (25X32VSIG).
I can not find a supplier for the eeprom.
Any help would be good.
Thanks Ian harrison.

Hi Ian,

Had one recently (check back threads) where pic had a digital 'LSD' apect - reset did the biz with mine.
Admittedy difficult to get to S/mode if it won't fire up - Chris.

Hi Ian ...This is what I got reading the flash eprom in the 24inch version ..
If you can use it to write a new 25X32 ...then you might be able then to access service mode ..and set to a larger lcd panel ..
good luck
Evan

Hi again Ian ...
before you do anything check the main boards similarity ..
Just been round to my shop to get a photo of the board I accessed ..
Turns out its not a CV109H....its actually a CV106LS1 V2.1
and the chip reference is U4 ...
sorry m8 ...
but am attaching a photo so you can compare anyway ..
appologies

Evan

Hello Evan,
My board (CV109H ) is different to yours.
I have attached a photo of the board and the power supply.
The eeprom U6 (25x32VSIG) is a W25x35VSIG.
I have identified pins 5 and 6 as the data and clock pins and have tried powering up and down with these pins s/c, but it still will not start up.
None of my suppliers list this ic.
Thanks for the input.
Best regards Ian.

Indeed Ian ..
You wont find it for sale commercially anywhere ..
The sets are made in China and Europe ..and I believe the supermarkets like Tesco and Morrisons ...expressly forbid information and serviceable parts at component level ..plus schematics and manuals to be released into the public or indeed service domain ..
How else are they gonna fleece the punters for new cheap appliances on a regular basis.
Its called capitalism and Churn

As to your problem ...its the same flash device ..but would need a good chip to read and make a clone ..
Sadly its one I haven't seen or read yet ..
Perhaps someone out there can produce a binary dump ?
..this way a clone chip could be made to fix yours up ..
Another reason why I'm pushing to expand the database started by Mulja
self help is our only chance ...and reading and writing these chips should not be elitist amongst capable service techs ..

Hi Ian ..
I suspect that will fix yours up ...good luck with it ..
But the idea of selling the eprom contents is what upsets me ..
Which is why I think we should try and build up a database for engineers..
I have no objection to anyone selling a preprogrammed chip ..
after all there is time effort involved insourcing ..importing and reading + programming..
But selling the code/contents at £15 for someone elses code seems a bit excessive..
Just my opinion of course
nevertheless ..I wish you luck with it..and hope you get favourable result.

Evan,

What exactly do you find wrong with selling eeproms?

[Turnip]

Hi Ohm,

Was the case - years ago, that manufacturers cared about after service, some gave a full manual for every set.

No complaints Ohm'wise as we all need to live - admit when recently at a Tesco spares site for bits they could only offer castors.

Pollux to 'em, though must admit like those piles of Neon/Technica at the roadside now local recycling has been discontinued with usual Tory 'efficiency' - green/recycling is for me - Chris.

Andy m8 ...I think you misread or misunderstood what I posted ..
I dont object to selling programmed eproms ...
That takes time ..effort and money invested in shipping and writing them ..
I do object to high prices for eprom dumps ..as the code inside is strictly speaking not anyones ..but the manufactures to sell ..
I give them first coup on this ...If they want to make the data available at a reasonable price ..then I'll say ..thank-you..
But ..they dont generally ..so it takes amateurs to access and make the contents available ...so I say ...lets share this info ...or at least only sell it for a nominal amount..
it is data ..and costs little as it doesn't have to be posted or packaged..just archived and made available..
Sent with respect
Evan

[E Parton]

Just as an afterthought Andy ..
would you be offended if someone bought a programmed eprom or spi flash off you .....read its contents ..and made the contents available on a forum like this one ?
Just curious m8

Evan.

Before I go into the specifics of  the answer. You have of course looked at the trade price & not the retail price before commenting & you do work for free.

I'll happily answer any questions herebot personally

Andy

Hi Andy,

Must just ask about that 'herebot' suggested, Wikky still has nothing on it - Chris

[Ohm Supplies]

Ok, I won't be able to answer everything.


What is a herebot :) were is it mentioned?
