20 Most Recent Samsung PS50Q91HD 50 in. HD-Ready Plasma TV Questions & Answers

I would not advise you to buy a non working TV specially when Plasma is moving out and the new technologies with 3D- LED is around bringing the prices down.
Also the cost is not the factor but if there is fault on the mother board then you are stuck and would have wasted money on a junk. So please do not commit UNLESS you can source a power supply unit - SMPS unit - and make sure that it is the ONLY issue. Let the TV work and then after seeing a good picture you can take tbhe risk... but the cost is also important and must be checked out.

The problem is from a capacitor inside the television, it is actually weak and as soon as it is getting heated, it starts to malfunction which results in the cracking up and dropping out on the screen you are noticing.

All you have to do is to open up the back cover of the television you will see some compartments with metal sheets that has tiny holes, unscrew them, they are covering the main board of the television.

After opening up the compartments, test the capacitors and check for the shaky one and replace it. Also any one you detect that it has swollen, replace it. couple the television back together and plug it to a power source and turn it on, and your television will be okay once again.

Take care
