Hi, I have a PlayStation 4 that won't start... and when it started, it couldn't be updated... My question is... If I copy the 25q40 dump and send it to you, could you repair it? I don't know if it's the culprit, but I'll try.

Hello,
After connecting to the mains, the backlight immediately starts flashing and no TV image can be controlled. When the connectors to the display are disconnected, the backlight is on and the TV can be controlled.

Most likely the problem is in the panel, install a jumper on the motherboard between points FB_TRDY_1 and FB_TRDY_3 and disconnect the lvds cables one by one and see which half of the panel has the problem.

I made a jumper. The TV remains on and controllable by both LVDS cables separately (only backlight, no picture, but responds to the remote). If I connect both cables, it flashes again and is uncontrollable.
I would be grateful for any advice. thanks

I'm not sure what panel number you want.

Try Dump IC1603

Unfortunately, it's still the same.

You installed the jumper correctly, you can take a look at the photo.

You installed the jumper correctly, you can take a look at the photo.

In the first case, I had it soldered incorrectly.
pin 1 (connector CN1300), last pin (connector CN1301_UT)

I just tried it, the TV does not restart. It can be controlled with both LVDS connectors connected. The image does not appear even with one connector disconnected.

[lotas]

That's how it should be.

[Maniacks62]

That's how it should be.

Tested. After connecting the CN1301_UT connector, no image is displayed on the TV. With the CN1300 connector, the right half of the TV works.

Well, finally the image appeared, look for the problem on the non-working side or try to mask the contacts...

You're great, thanks for your help. I covered the contacts and figured it out. Something went wrong with the display in the lower left. You can see it in the attached photo.

Well, it looks like you were unlucky, remove the front frame and inspect the glass under a magnifying glass for burnout (on new panels, the line drivers are built into the glass itself and cannot be repaired).
