Video shuts off after...

Video shuts off after a few seconds. I have replaced mainboard, inverters and eeprom chip

Technician's Assistant: What's the model number of your TV? How old is it?

Insignia ns-55l260a13

Technician's Assistant: Does the TV menu work? Do you have the same problem on all sources/inputs?

No video to see menu all inputs

Technician's Assistant: How long has this been an issue? What happened right before this popped up?

When it first started messing up, the left side of the screen would be a little blurry and dim, then it would start getting normal

Technician's Assistant: Anything else you want the Expert to know before I connect you?

I can't think of anything

What you are describing is classic t-con board failure ,this board drives the LCD display and a classic symptom is blurriness one side

Ask Your Own TV Question
Customer reply replied 5 months ago
Ok, that is the one board i haven't replaced.

The t-con is located usually at the center top of the set sometimes covered by a metal shield

Ask Your Own TV Question

Yes one very important thing...order by part-number only found on the board itself

I replaced the t-con board, the screen comes on, then goes back off, comes back on again and goes off - about 5-10 seconds for each. do not see any menu options for video input.

This is different from your original issue you are sure both part-numbers are the same on both boards?

Ask Your Own TV Question
Customer reply replied 4 months ago
exact part numbers. i don't remember if i put the original or new inverters back on - i can try switching them out. This is what it was doing after I switched out the power board and inverters. So almost all the parts have been replaced. I couldn't find a new board for where the eeprom chip is, but that is new also (the chip). When it first started messing up, it had the blurred video on left of screen but after a while it just started powering off

I do not think this is to do with the t-con however you may need to put old one back just to prove that assumption

Customer reply replied 4 months ago
well i switched the inverters and it won't even power on now so i am switching them back

No I mean get back to square one by putting the old tcon back in

Customer reply replied 4 months ago
its powering on, but still doing all the same things, shutting off after a few seconds. there is only one board i can't find, which is the one with the eeprom chip on it. What else would make it not stay on?
Customer reply replied 4 months ago
it is doing same thing with original tcon

You may have a problem with the LCD panel itself

In other words the screen,

that isn't fixable is it?

No its not an option to replace the panel itself

Ask Your Own TV Question
Customer reply replied 4 months ago
ok crap, thanks anyway!

It could be the backlights themselves bad or the panel itself both are not good

Ask Your Own TV Question

Your boards you should be able to send back

Customer reply replied 4 months ago
ok, a friend gave me the tv anyway, so at least I am only out a few parts :)

OK sorry for dismal news

Customer reply replied 4 months ago
thanks, ***** ***** try - electronic parts aren't normally returnable. At the very least i can re sell them as used.

No they should take them back but charge you for restocking
