Hitachi Plasma TV, p42t501, faint horizontal line travelling

[JCS]

I have an Hitachi plasma tv, model P42T501 which has a faint horizontal line
which travels up the screen, there is also a slight buzzing sound. I
suspect these problems may be due to a leaky capacitor on the power supply
panel. Any suggestions would be appreciated.

Thanks

John

If it's not in warranty anymore, what keeps you from carefully opening
the case and inspect all capacitors for obviuous damage (leakage,
burst-open lid) ? Also, I'd check the caps in the powersupply with an
ESR-meter then.
