SOURCE: samsung plasma ppm42s3 , picture wobbling,sometimes screen goes blank

Hello arunaik_6,

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,

Thank you,

Check the speaker/s. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis.

does the tv have an indicator lights that are lit on it while plugged into an outlet? check your power cord and the outlet. if you're still having an issue powering the tv on, you may need to replace the power supply board.

Samsung Plasma 42" TV - 2006


Hi, this is quite a common problem for plasma screens and LCD screens. The fluroscent backlight is more than likely faulty and would need replacing. The best thing to do is to take it to a service centre because there are no user servicable parts inside the plasma.
