This TV appears to have put itself into acid mode. Resetting the colour etc. settings to the default hasn't worked, and neither has the "factory reset" setting in the super-secret service menu. Spoke to two local repair firms - one wouldn't be drawn on what it might be, and the other suggested the panel might be shot, while interpreting random people on the internet suggests that it might just be one of two boards. The OSD colours look a little off, but this may just be because of the transparency. If it maters, onset was sudden.

Any ideas, lads?

If it's playing up on all input sources, then it won't be a simple fix. I might have a better idea of what's wrong if you can get me a photo of the TV showing a test card.

TVs generally die because of the capacitors failing.

Finding the one tiny component causing the problem isn't a walk in the park

From top to bottom:
- That JPEG off a USB stick
- A video off of YouTube
- The same video with the TV's "Blue Mode" on (which it wouldn't let me do with the JPEG showing)

Bad caps, man. There was a spate of them, RS got custom out of it I'm sure. You could make a bit of pocket money buying spares/repair screens on ebay for peanuts, chucking in 50p of new caps and reselling them.

Not a clue mate, sorry. The difference between the image and the video rules out any of the obvious suspects.

Those first pictures - is that using its internal tuner, or an external box?

It kind of looks like it's interpreting a YpBpR or YUV picture as RGB or vice versa.
The chatter down an HDMI lead that a box has with a TV, where the box reads the capabilities that the TV offers, and tries to pick some settings that will work (EDID) certainly includes non-RGB display options.
Short answer: It's bloody odd. Try a new cable, and wiggle it (also, turn _everything_ off for a while.
I can see why shops aren't offering guaranteed fixes.
Have you searched for model number , colour (or color)?

It's hard to tell from that picture, is the Jpeg off a usb stick normal, or are the colours off too?

The first pictures are off a Virgin TiVo via HDMI, as is the video (via YouTube) in the second. The HDMI cable is as supplied with the box, and is working just fine on the backup TV (which is then older model from the same manufacturer).

It may be difficult to tell because I was using my phone camera in the room at night with no flash, but Carole's colours are off in the JPEG as well. Again, the JPEG is from the TV's internal picture viewing app reading it off USB where many of colour adjustment functions aren't available, while the video is a YouTube upload via the cable box, so is potentially an imperfect reproduction using different compression. I'm guessing that it probably isn't the panel, since on the YouTube app on the box stills from 2D animations just looked as if the colour had been turned up, while stills from live-action were in "acid mode", and if it were the panel both would be ruined. To illustrate that, here is a picture of the YouTube app on the this set (top) and the backup set (bottom).

The quality of the photos may make it difficult to notice, but the second still on the top row should look like this, and take my word for it that it does on the bottom set.

Turned out to be one of the chips on the t-con board. £80 in all.

Elaborate mate.

My TV is dying on me. It looks like OP's picture but the difference is that it becomes okay after a few minutes. Maybe it is a different issue?

What happens if you turn it off and immediately back on once it's fixed itself?

It will be fine until the next morning. After waking up and turning it on, it goes mental again.
