Subject: Philips 28PW6506/05 Picture starts off compressed into vertical strip in centre of screen

Philips 28" TV
Model 28PW6506/05
Chassis CH 28RF PSLLR S10W 10P

On power up the picture is compressed into a vertical strip in the centre of the screen. This will expand outwards to the sides as it warms up. The picture may flicker as it stretches outwards and the set may shutdown. It can take 5 or 6 restarts to get it to hold centre at full size. Also, the picture is unstable on the right-handside and distorts when there is a very light area on the picture. The lefthand side is stable.

I have removed the case and can see no obvious damaged components.

The set has been retired to the garage before it fails completely but I would like to get it running again.

Any help you can give will be appreciated.

Thanks

Possibly bad solder joints in the power supply or horizontal deflection areas.

I think its probably more bad-capacitor related if it is gradually expanding outward.

The problem started as a slow and steady deterioration. It didn't simply just appear. It does seem to be going downhill in a gradual if somewhat exponential way.

For 10 points... can you name that capacitor?

(there are none that look all swollen or show any outward signs of problems)

something electrolytic near the HOT. Probably very close to the heat sink. I know that isn't as specific as you're hoping for, but it's as good as I can do.
