Unfortunately, that board is the inverter board. And for this model the inverter board is only supplied with the the PDP panel. The panel is quite expensive, here's a link if needed:

Samsung plasma TV cooling fan didn't turn on and the TV overheated. Tried replacing with a new fan, but that fan will not turn on either. TV works just fine with back cover removed and a 12" desk fan...


the is a fuse on the board if you follow the power line on the board back to the main power board you will find it. also test the volts with a meter just make sure you have volts. some of these models also have a thermal switch that then the tv hit a surtan temp the fan kicks in.

Can your power cord be bad on a panasonic plasma tv to cause it to turn off and not start again and blow a fuse on pb


The main power regulator board will have some shorted component/s on it. Normally, these boards to plasma TVs are irreparable. Card base replacement should be done.

Which one is the main power fuse in a vizio 42


The main power fuse is not to far from where the power connector plugs into the power board. If this fuse is constantly blowing, you have a dead short on your power supply board.

42in samsung plasma have sound no picture


Hello,

Problem is in either power supply or the Y-Sustain board.

The Y-Sustain is a relatively large board out of which go connections to the side of the display; it's therefore closer to either the left or the right side of the display, has at least one rather large heat sink on it and fat power cables connecting it to the main power supply.

Often there are fuses on that board - one or more. Check those.

if they are blown you can try to replace them, but expect them to blow again - usually the whole board needs to be replaced.

Good luck in solving the problem also be careful in handling the set because it contain high voltage....

The main fuse went , I nee to replace it, but don't knoe the Amp.


Hello
Normally Plasma 42" TV uses 240V 6Amps fuses. But if the main fuse should blow up there must be any reson for that. Without retifying it, if you put an other fuse in place, it also will go out in no time as you switch on the set. So make sure that there is no short in the main power regulator section before replacing the fuse. If you are not sure about it, please don't make things worse. OK.

often that *needs* to be done in a service center as there are some adjustments to be made after replacement; don't know about this particular TV model.

Hope this helpout........

Remove the power supply cable to Y Main board, check Vs on power supply board when you turn on tv.
1. If you have normal Vs, replace the Y Main board. If still not work, replace the Logic board.
2. If you don't have normal Vs when you try to turn on your tv, just replace the Power Supply board.

Electricity went out in town, tv won't turn back on.


On this type of problem, the first thing I check is the AC line fuse on the power supply. Follow the Ac plug wire to the power supply board and where it plugs in, you will find the fuse. If: Then: It checks bad. Replace it. It goes out again. Call a Servicer. It is good. Check for the five volts that goes to the Main PCB. No five volts, change the power suppy (SMPS) Five volts is there, more than likely the Main needs replaced and SMPS. For a Samsung Servicer in your area: 1-800-SAMSUNG
