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

[tec3000]

here another pic. You don't see any blue line here. It was invisible, even though it was there at the time.

[Davi.p]

Ok but now you moved the tv.. i mean this is why, not the flat cable..

[tec3000]

I don't think so. Did you see the pictures I attached with the first post? There you see how the i-Manual was until two days ago. No issues there. It ONLY happened after I disconnected and reconnected the flat cable.

[Davi.p]

Are the lines moving? if them are moving then a possible damaged cable, but if them aren't it cannot be that cable, the cables doesn't control single lines them controls at maximum two or four pixels at the moment..

[tec3000]

There was one horizontal line. It was definitely changing colours. Most of the time green, sometimes red, but also greyish/black. The grey/black line was very thin. It was only visible in bright scenes. When scenes changed the colour of the line also changed.

And the size of the line also changed. Sometimes it was a straight line from one end of the TV to the other end (left/right), sometimes blocks of smaller lines.

Only lately I noticed another horizontal line below this one. But not as large.

And the vertical line also changed. Sometimes not visible, sometimes a clear blue.

.i.mean.NOW...

[tec3000]

No not moving while the TV is running. It was worse though when I first disconnected the cable. After playing around with the cable (straighten it a bit) half of the screen is now full of lines. STATIC.

Ok guys, you convinced me. I will do it...Also I think I made a mistake yesterday. I disconnected a cable from the T-CON board. I think Diah that's exactly

the ribbon and LVDS i think you should know where... and do what i asked you before. no more or less.

[Diah]

LVDS need to clean them from the main boards side.

[tec3000]

Diah
alright, thank you for marking the CORRECT cables. [Super, ich hab also die ganze Zeit die falschen Kabel rausgezogen. Ich nehm's mit Humor....]

About the ribbon cables. Just to be 100% sure: You want me to take the ribbon cables carefully out one-by-one and turn on the TV and look if it stays on or not, correct?

[Diah]

LVDS clean them from MB side to get rids out the disruption in picture you have right now.
remove all 4 ribbon together to check the LED BL turn on and remain on so when you attempt to repair LED, at time the screen out from set..let you always can check and see that all yours LED BL lit on with out screen,i

who knows could be the turn off issue fixed too by cleaning the LVDS

so I took out one of the LVDS on the mainboard end, had a look and just plugged it back in and first pic happened. Then I played with the cable and plugged it back in and i-Manual is almost as good as it has ever been. (pic 2) BUT Diah can you take a look at pic 3 and 4 and tell me how I should clean it?

And in pic 5 you see the ribbon cables. Any hint how to carefully disconnect those cables? I should first peel off the tinfoil right? I really don't wanna mess this up....

stop to do any more on cables as you have now very clear screen., except the LED defect shadow ... i think now its enough reason to give you encourage to repair LED BL and have full function TV.... good luck.

Thank you, It's been a rollercoaster journey so far, but I'm highly motivated again.

I'll watch some YouTube videos and then get to work. So if I understand you guys correctly I can only order the backlights once I have removed the screen. So right now I can order a couple suction cups.

That's it, right? Or is there anything else?

[Donny2derby]

Another pair of hands is more useful than suction cups. Many hands make light work as they say.

It's so valuable to have that additional help. 4 eyes and 4 hands is double the opportunity to see what is right and wrong or spot something the other person might not.

And lifting things off with the help of another as opposed to with suction cups is far more stable.

But yes. The first thing to do is break the telly down to the backlights, then read their part number and order the exact same type.

Yeah, I will definitely have some help.
OK, I really hope I will be able to find the correct backlights.

Thank you!

Suction cups work fine, you don't need extra hands, I do it all the time. If you have two of these spaced out, there's no need for another. You don't need to remove the screen before purchasing the LEDs, of you have a room that is empty and no animals or anything is going to go in there, then fine. Do it so you feel good. Just make sure two things. One, have the ribbons/buffer boards taped with masking tape to the screen so they don't catch anything when you pull the screen off, be gentle with bending them, but they aren't as fragile as you'd think. And two, make sure you run a paper, not plastic, card under the screen along all the edges to make sure the screen isn't glued down (after bezel is removed). Except for the bottom. Sony doesn't usually glue the screen down that I've seen but if by chance it did, you can break it trying to pull the screen off. If there is tape/glue then you want to suction the screen semi close to the area and pull up gently and slide the paper card under the screen to release it. Once you've done that stick a piece of paper or cards under those areas so it doesn't restick while pulling it off. And then suction and pull straight up. Likely it's not glued but who knows. I prefer the double suction cups because if one of them fails, you still have one that will hold it.

Good luck, we can answer questions as you go as long as you put some pictures also.

AND when you put the screen back on, you are going to want new grounding tape to apply to buffer boards. You can probably use old tape but I always put new tape.

Thank you very much. I will order the same suction cup. I was opting for single ones but this looks legit. And thank you for describing everything in detail. It really helps. Just need to find a video or two and see it all in action before I do it.

One more question: When you say I don't need to remove the screen before buying the LEDs... how do I know which ones to buy? And how many do I need to buy? TV is from 2013.

Much appreciated!
