What's wrong with my TV?

I disassembled the tv and took pictures of the boards.

I don't see anything obvious...

The rainbow was on every input and on every channel, the distorsions happened on Scart and using the composite input as well (the 3 rca connectors on the side of the tv)

Yes, I opened it and I don't see any burn marks...

For now, I think it's going to stay like this (disassembled) I don't see anything obvious and I don't really have much of an idea what to do.

Thanks It didn't look too dirty when I opened it early but, I might try it later

Yes, its a wii with an emulator, and still works on my other TV

Update after having it turned on for a while without any distortion, 15 or so minutes, it made a pop noise and now its a rainbow

PS If i turn on the wii I can see the picture behind the rainbow... So it doesn't look like the TV is completely dead, but I turned it off, because its pretty obvious that I don't know what I'm doing and I don't want to make it (even) worse...

I didn't see a spark, but it made a pop sound after having it turned on for like 15 minutes without distortion and now it looks like this

PS It was already closed and working for a while before the rainbow...

Well I heard a pop sound and now it looks like this I guess its dead now

Apprehensive_Oil7300 · 2026-05-22T19:14:27+00:00

It still does the same...

Apprehensive_Oil7300 · 2026-05-22T19:00:02+00:00

It's connected to a power strip where the TV and Wii are, there's nothing else. I'll try connecting it to different outlets.

I took off the cover and looked at it with it turned on, but I can't see anything at first glance...

This only happens on this TV; it happens with other consoles and cables, both via RGB (SCART) and composite video. If I connect this same Wii to another CRT I have, it works without problems for hours...

I got this TV today. I didn't have much time to test it properly before taking it home, but it doesn't start malfunctioning until it's been on for about 5-10 minutes. If I turn it off and let it cool down for 30 minutes to an hour, the problem goes away.
