Hi everyone,

This morning my 5 year old Sony KV-28DX20U TV started playing up. The
power light goes on, sound comes out but no picture. After a minute or
so, a green tint appears over the screen and then the picture comes in,
but with a green tint.

I believe the Sony's have a self-diagnostic feature, but can't find
much about this.

The red power light comes on and blinks 5 times, then goes off for
about 3 seconds, then blinks 5 times, etc.

Hopefully it's something relatively simple, as it's a great TV and I've
never had any problems with Sony before. Anyone able to help / offer
some clues on this?

Thanks!
