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.

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,

Hi,
If your using cable as your input signal see if the TV also does this when using a DVD player or game device. This way you will know if its the TV doing this or your input signal causing the TV to respond in a faulty way. If it is the input signal causing this then adjust the 1080i settings make sure they match what the TV is set too. If the TV does this on any input signal then there's a problem on the xy-sustain boards. This problem is easy to service at a repair shop and shouldn't cost much at all to replace sustain boards....

Samsung PS-50C91H 50" plasma no picture


If this set has a cable box, satellite box or even a receiver hooked up to it remove power from them and the set for a while and power back to see if a reboot cures this issue.

short of that someone who is willing and knows how to check things is going to have to look inside and test things, repair if not what I have suggested consists of replacing boards which can either fix the set or not and gets expensive.

Make sure the proper input is selected on the TV menu. Try other video inputs with different cables and try another device like a DVD player and see if you get video through that.

Sound but no picture


You popped the plasma HV generator. Do you use a UPC all the time, if not then power line surges or brownouts can cause this type of problem. Needs Pro shop repair, expect around 450.00. PS: buy a upc for around 10 minutes run time $80.00 ??
