Can someone tell me what voltage I can inject with a variable PSU to test the backlights please?

Set powers on but black screen. No backlight no picture.

I have the back cover off it and there are no lights showing thru the small holes that light usually shines thru, as in back light.

I have seen them light up before and work but they might have been damaged when I was playing around with the TV.

No audio.

I don't have aerial connected.

I suspect the power board and that's why I would like to know what voltage I can inject to see if the back light is there.

Thanks for your input.

If i unplug the tv and power on after a bit of time has passed, the tv runs fine for a couple of minutes before it returns.

If anyone has suggestions of what might be causing this id appreciate the help, was thinking it was maybe a faulty main board or tcon board but not sure, cant see any noticeable damage to the main board

The screen only shows lines. Why is this happening and how can I fix it? Thank you.

Second  row says::  SERIAL NO: TR1DAM024100535

Third row is a bar code

The sticker on the tan board has three rows

First row says:  0500-0405-1340

Second row is: a  bar code

Third row says: 20I333C9P149502

On the tan board sticker in the third row, I believe the third character from the left is a capital eye  (  I  ).

The problem is the  TV all of a sudden decided not to turn on.

 First there was no red power light illuminated at the front bottom center of the TV. Then after unplugging it for 30 min, when power cord plugged back into the tv, the power red light illuminated but the tv still would not turn on, neither manually nor with the remote.

Removed back of the TV, checked continuity at the white horizontal fuse on the tan board, and meter said it was good.

I have no idea what is wrong with it and can only assume it is some sort of power supply problem.  Although that red power light illuminated after removing the cord from the tv for 30 minutes.  So apparently something is getting power.

Could you tell me some other items to check in order to try to isolate the problem.

T con board? Main board? Ribbons? I can replace them but not sure which one it is or if it's actual LCD. No damage has been caused to TV

These only go 2 3RDS across the screen aswel they do t go all the way, not from what I can see.

I checked it with a flashlight and it seems there's a faint image

The screen blacking out is happening randomly between 10 minutes and 2 hours

When I switch on power , standby mode button glows red

⟐ Answer unaccepted December 04, 2023 at 5:02 MST

It spans the whole lenght of the panel, but it's only noticeable on those colors moving towards reds, like orange, but not towards blues

Lines are more or less noticeable depending on what's on the screen, for example, that's a dynamic background, the line is more or less noticeable depending on the amount of falling snow near the area

Tried power cycling the device only, but somehow I doubt this is a software issue?

I haven't read about this problem in other TV sets, it's always the usual vertical or horizontal lines but I can't find discussions about this one
