Question about Samsung PPM42S3 42 in. Plasma Television
This tv works fine for a 45-90 minutes after that problem starts picture starts wobbling, screen gets snowy & worst screen goes blank but sound remain.If i swiched off for 30 minutes again i can watch for another 30-60 minutes.
This looks as if a component has become thermally sensitive. The best way to find this is to use component cooling spray. It looks as if the problem is localized to the tuner section. Take the back off of the TV and turn the TV on, wait until the problem occurs and lightly spray the tuner section with the component cooling spray watch for any reaction, then if this does not work spray the Microprocessor and the LVDS section and watch for a reaction. The set should go back to normal when it does that section is the problem, try to localize the problem to one component. Then replace that component.
I hope this helps,
