Default Toshiba 21S04BG, colour tearing when warm


Toshiba 21S04BG CRT TV: after about 5 minutes the green starts to tear
on highlights and the picture develops an even mild-greenish hue.

Setting the colour saturation to 0% gives a well balanced monochrome
picture with no colour hue.

Power-cycling the set in the 'warm' condition rights the problem for
~15 seconds, as does selecting a different preset colour 'temperature'
setting using the OSD.

Before I reach for the freezer spray, can anyone point me in the right
direction, please?

Thanks
Andrew

Ditto! Andrew I am getting exactly the same fault as you on my Toshiba 21S04BG set and am trying to find out
the problem.

George, It's good to know I'm not alone with this fault!

I'm hoping that if we've both got this problem then it could be a
common fault with this chassis with a known resolution. Oh well, here's
hoping that someone will come along with a "Check X,Y & Z" type fix for
us.

It's been over 15yrs since I repaired brown goods fulltime so I'm quite
out of touch. That said, I'll try and put some time into this over the
weekend and make some progress.

Make sure the service switch, likely on the crt board,
is ok, & check solder connections on the main board,
as well as the crt board. Sky.
