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

[tec3000]

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.

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

[Diah]

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

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.

right now what we did saw..and know ,,
1- the strips LEDs unit went blue color cause of burned the surface of them..( we don't need to explain the chemistry of LED )
2- the first filter also effected with some burn from the LEDs surface. ( this need to try clean them how much u can with out damage the coating )
3- from the photo you upload for LED driver boards there are much brown area happened via heat ( over load ),, until now we cant say this boards got issue or not.... as the reason was the strips
also you are now removing the reason with new strips then you can go back to others points if there are an issue.
so step by step repair called

Hi, I finally got the LEDs. I attached them. So far the TV doesn't turn off! (I tested for 15 minutes. Never lasted this long with the old ones)
So far so good BUT:

Please take a look at the new pic. One strip has far more light output than the other 3 strips as you can see from the attached picture. Any ideas why? I wanted to do the reassembly now but not sure....


edit: It's actually not the entire strip. Only the outer half. Towards the edge.

Diah Alright, thank you for the explanation. Once the strips arrive I will let you know. Appreciated!

NO. we need to do our best when you bring the broken one together at or nearly to 100% to avoid any light reflection or shadow,, because its located at he light source,
so to avoid the filters which mounted over ( under the LCD ) in crease any issue at light reflection.

OK understood. I will pay close attention when gluing the pieces together. Thank you!

Can you have a look at the pic I uploaded? This is from the other side. I haven't touched that side yet. As you can see there is a gap where the two filters meet and blue light shines though. It was already like that. Is that going to be a problem? It's exactly in the middle of the top of the TV

[Diah]

Thank you for the detailed description! I have now sprayed some alcohol. Tomorrow I will try to remove the strips.

I was also able to remove the other filters now without any problem! Nothing else broke. I was worried about the broken parts, but I will buy a UV-Kleber and put them together.
So if I understand you correctly it doesn't need to be 100%. Just have the filters at place. Right?


BTW: Strips are on the way now. 4 days in transit. I think it will be here sooner than I thought.

Thank you for assisting me!

about the broken one... you can put them together with ( Sekund Kleber ) or ( UV Kleber )
i will recommend UV one as its 100% transparent and you can do it first in room then take it out under sunshine... just be sure it remain straight.

Davi.p : when you will stop upset sets owner with yours rubbish comment... did you have eyes problem or its indeed one of yours hobbies to upset others ... can you explain yours professional what will yours genie 3V batteries will do with double LED unit build in double opposite zener protection Diode !!!? please please explain to other before you are talking on professional....

I also don't know what to do now. And where to get new filters/diffusers. I still don't know which is which.

ignore such things which bothering you...

1- to remove the strips you need to push the strips at socket forward so the clips which hold it will be in the wide area so you can pull them.... install should be opposite things see the photo
2. to avoid the other side filter from any damage.. because it may burned and stitched to LEDs surface... spray the whole with alcohol over night so it will move easy.... the one which break... try start to clean it how much you can

[Davi.p]

Ok, this is probably the end, but i want to repeat the move to dismantling the screen without checking well the led control board is definitely a rookie move.. as you can see led strips are not normal led strips (in series), leds are driven individually, so some leds not lit could be because of bad driver board.. this is not a professional way, this is a very well build tv set, sad seeing it go to landfill

[tec3000]

Sorry, i don't understand, each led can be tested with a 3v battery and a series resistor, so you broken a diffuser? And now? It's important to know if leds are ok, if you can or not continue the repair..

[tec3000]

have you tested each led ? those can be ok.. (!)

I can't. The filter is in the way. I tried to carefully remove it. Result is above. It breaks very easily.
