The Hyper Module Is Defective / It Is Located Behind The Jack Panel On The Signal Board.
More specifically the 11 16v/10mf caps on that board need to be replaced... Not expensive, I do them for under $100.00 dollars..

Hello,

The problem is from the lamp of the television, it seems to be having some faults, it is gradually getting damaged.

It will start by being wavy until it goes completely blank.

Some lamps go for about $125 or more. Some go for $200.

Take care and Good luck

Samsung T.V. goes on for 30 seconds then no picture


If this is a flat panel LCD tv, this is a sure sign that the panel itself is bad. I have seen this before. Tv comes on works fine then within 5 minutes goes blank.

Wavy picture


this is caused by a bad convergence module, and there are probably some dried out electrolytic caps in the circuit as well. i have one in the shop right now that came in with the same problem. if you have it serviced, make sure they replace all of the convergence modules (there are usually 2, but sometimes 3 of them), because if one went bad the other(s) is likely to go out soon as well.
