Sony LED 65X9005A shuts down after few seconds - looking for help

[lotas]

It shouldn't be like this, you have the maximum current flowing to this strip (the driver may not be fixed or the mosfet on this channel is broken) and these LEDs will not last long.

Man, the TV with out signal..... ( MO SIGNAL ) sign will show on the top left of the screen.,, this strip are lighting more... this is the local dimming process.. after he put the screen in place and fed it with signal then yours theory will be checked if there issue with lighting.

[lotas]

And when the "SONY" screensaver lights up, should this corner also light up?

no screen saver.. only option at setting to turn off if no signal... who knows if it set on.. we wait and we will see the screen how it look with signal

[lotas]

Let him press the MENU button with the remote control and see if the local backlight changes or not!

dont bother of more light or less... you don't have the screen in place and no signal the dimming process will be different.., put every things bask as it should.

ok perfect. I'll try to it today. Will give an update when I'm done.

Right now it's impossible to test. I should do it when I have everything back in place, right???

[Diah]

we saw from early photo of his LED driver boards not in good shape... many over load mark had on the boards.... still this is not important now... he got rid off the issue turning off... later if screen in place will be clear to judge and another repair steps take in place if there issue with lighting.. right now put every things back

[tec3000]

Ok, I was able to put everything back together. TV doesn't shut off anymore! And I was surprised to see that light output was even. It wasn't blown out on one corner!

But I have new problems....

Picture had weird artefacts AND two green thick vertical lines. I was able to get rid of one line when I played around with one LVDS cable. (Pic 1 and Pic 2)

So silly me thought it was a good idea to keep the TV on while disconnecting and reconnecting the LVDS cables. I think something must have happened there because since then whatever I do I only get a washed out white image (Pic 3).

And in Pic 4 you see the cables. I circled a few spots. Do you think it's just the cables that I need to replace or do I need a new T-Con board? ://

I know I somehow messed it up again

[Diah]

good work for you as it first time to be encourage to take TV in parts and yon have less info on parts..

the end result of line or green line now more noticeable to you.... try to clean LVDS and ribbon cables with out damage them..... other wise you can live with it.

[lotas]

There is no need to clean it, but it needs to be changed, 1.2 pins do not have contact with the connector.

[Davi.p]

them are hard to find parts maybe, a restoration could be made, but needs expert hands / tools..
this is not a tv for homemade repairs i think, generally i see not a good job (halo areas and etc..)

[tec3000]

so this is how my tv now looks

I wrote above that now we need to change the cables, what kind of defect is there on the panel, a crack?

[tec3000]

Yeah, I didn't even mention that yesterday because of the bigger problem. Luckily it's not a crack. I'm not sure what it is. It happened after I put everything back. Something on one of the sheets maybe? Like a piece of tape? I'm not sure. But it's definitely not a crack.

About the cables: Can you guys help me find the correct ones? I don't know what to search for. You have some eBay/Amazon link? That would really help. Don't wanna buy something wrong.

And it's also possible I need a new t-con board cause it started smelling. I think I did a short circuit, but I'm not sure.

Maybe buy new cables first and see how it goes?

[lotas]

First, inspect all four connectors under a magnifying glass to see if there are any traces of conductors left inside them from the cables (they can short-circuit the contacts).

[tec3000]

Alright, I will do it shortly.

Thank you. But that's with a t-con board. I first wanna replace the cables first.

[lotas]

But if the T-con board stinks, then it may have suffered too, but here is a complete set and just for your “65” panel, well, it's up to you to decide.
