Toshiba 26" lcd problems

[Gootch24]

Ok heres my new dilemma I have a toshiba 26" lcd
model # 26 AV502r The top 1 inch is crystal clear and the rest is fuzzy (see pics) Ive changed the t-con (ebay board) and the inverter guess all theres left is av/Main board but before I did was wondering where I should look otherwise or give you tv brainiacs a lil challenge,Thanks in advance guys,Gootch24

Could be a faulty panel ,have you ever seen it work properly?
Could be faulty cables or connectors not seated correctly. Try cleaning flat cable contacts.

It looks like the picture is ready to roll like when you lose the vertical sync, in my case, it was the T-CON board after warm up.
Does it get worst after warm up? I also would clean the ribbon cable connectors as suggestd by selldoor.
By the way, with the new T-CON board, the problem stays the same? Worst case will be the LCD panel.

Nope , never had the luxury of seeing it run properlly, Ive checked ALL cables returns everything ,like I said havent checked voltages or anything (could use a direction on this) or changed main av board,Thanks

Ive checked ALL cables returns everything

Does "checked" mean visual inspection or cleaned and reseated?

Re: Toshiba 26" lcd problems

Ive pulled all plugs and reinserted, didnt clean them . After I put the new (ebay) t-con in I turned it on but I didnt have any components or antenna hooked to it but could swore it was clear for a couple of seconds then got that line of clarity at the top again like I blew the t-con,but wasnt sure kinda even questioned myself and asked "did that just flash to a bad picture again" what would you suggest to clean the connectors with? And yes I also unplugged and replugged everything back in. not sure what a bad panel looks like ,anyway,thanks

budm said it in another thread that he is using this one:

I have to do the cleaning myself, so I have picked up one myself.

Re: Toshiba 26" lcd problems

One thing about LCD panel is that it cannot display double images by itself since it has X/Y scanning controlled by the T-CON (Timming Control board), it will display or not display what the T-Con send to the X/Y lines.
From what I see on your screen is double images.

Re: Toshiba 26" lcd problems

Are you suggesting a x or slave board, hmm I thought there was only 1 board in this tv(inverter), maybe Ill go get the service manual and do some reading quick,Thanks

Re: Toshiba 26" lcd problems

The X/Y drivers are part of the LCD panel assembly, the T-CON send decoded signals to them to produce the pictures (paint the picture on the screen).
Please read the PDF.
