Sylvania 42" flat screen won't turn on

I have a sylvania 42" flat screen tv and it made a loud noise and turned off. When trying to turn it back on it would start and then turn off again. I tried this 2 more times and then a burning smell came from the back of the tv

    You have a shorted diode. The repair is simple. You must snip one end of the diode and lift it just above the board. You will not replace the diode. What you will be doing,is disabling the standby light. The TV will operate just fine with out this. I need the model of this TV, to provide you with the location of the diode. Thanks for asking, Matt of Martins TV Repair.

First you should check the fuse and the wiring in your tv by removing the back cover. Make sure no wires are bare or touching. If there are any, wrap them with electrical tape.
If you cannot see anything wrong by looking, then it is probably the set has a bad transformer (high voltage)

Have a sylvania 42" plasma about four years old. when i turn it on the red light turns to green makes a clicking noise and then goes back to red.


Most likely has bad capacitors on the power supply, but there is a troubleshooting process one can do with the back open to isolate the bad board. You can open the TV and look for swollen caps.
Boards cost about $100 each so its important to guess correctly

There was a power surge and a loud pop and now the tv will not power on. The red standby light is lit, but when I try to turn on the tv, the green power light flashes twice and then goes back to the red...


A job for the technician on this one. I have only worked on several flat screen before, on my last days as an electronic technicians. Half of the ones I worked on was the power supply inside ir the problem was like this. Instruction on how to fix them would require me to write many pages on electronic theory so, I am very sorry It is almost impossible for me to help you on that. Be carefull where you take that tv to. some shop can't fix those. You may have to search your local area for someone who specialize in flat sreen HDTV. Well I hope I have shed a little light on the problem. Thanx for posting the problem.
