Sony KD32DX51 colour problems	Can't Post

Hi,

After having a perfect picture from day 1, my 4 year old Sony Wega KD32DX51 CRT tv appears to have suddenly developed a fault.

Sometimes the picture is perfect but on some scenes, about half a second to a second after the scene has changed on screen, the colour suddenly either develops a peachy tone or appears to over-saturate. It depends on what the picture on-screen is. This is also occurring with menus and on all video inputs.

Any advice on what is likely to be wrong, how it can be fixed, and how much a repair is likely to be would be much appreciated.

Many thanks,

Kroma, UK

Having observed the tv a bit longer, it would seem that the 'peachy' colour is a slightly pinky/peach hue.
I can't understand why the picture is sometimes perfect and why it sometimes 'blooms' into this peachy/pink colour. Also, some scenes are definitely over saturated.

Thanks,

Kroma

Sounds like an intermittant short in the CRT or a bad solder joint on the CRT board. A solder joint can be repaired but the CRT cannot.

Thank you for the advice.
Next question - is it possible for a bad CRT to get better with time? 2 weeks on and the fault isn't nearly as noticeable now, and it's not just because I've got used to it!

An intermittant condition may clear up temporarily but willl not repair itself.

I have never had much luck in trying to rejuvinate or clear shorts in Trinitron tubes with my BK CRT tester.
