My fujitsu plasma tv has sound but no picture


check connections most likely culprit is a blown fuse on the screen mainboard very easy to replace but must be soldered unless you use a little bit of copper wire twisted and rolled up to cover both ends of the internal fuse then stick it down with insulation tape but do this at your own risk

My plasma tv has just lost it's picture. I do have


There will be a fault in either the Y or Z sustain boards, these are responsible for driving the screen 9hence sound but no picture). The popping sound willhave either been a fuse blowing on the board or another possibility is one of the drive ICs on the buffer board has blown. If so it's best to replace the board.

Heard a pop then screen went blank. Now TV wont turn on.


Sounds like your fuse.

If not the fuse in your plug, then the internal fuse in the TV. to get too this you need to open the TV by taking off the back plastic panel and look at the fuse.

the fuse is the glass tube on the board, will no doubt be near where the power cord connects to the TV. and are easy to replace with another fuse. you will know soon as you open it if its blown as the little glass tube will be blackened or the little wire inside the tube will be missing or severed.

Fuses in TVs are actually designed to blow over time with ware (usually to last a bit longer then the warranty time frame) so after the cover has ended the TV can go in for repair work at extra cost. Its a little known fact.

My toshiba rear projection TV's picture just went black. Sound is good just a black screen.


high voltage is not coming up. possible fuse locates on power supply board on the right if you are sitting behind set with back off. if fuses are good, possible horizontal output transistor shorted. sounds horrible but easy repair

Rca tv won't power on


it may need a Flyback Transformer or a burnt capasitor and resistors. there are many posts with this same problem. Some a little different. Check the fuse just inside where the power supply cord goes in . if the fuse is blown you will have to find the reason it burned . But maybe you will be lucky and replace the fuse. And it will turn on. but I think that only a TV technician can fix the problem.I have a background on TV repair and I think it's the Flyback transformer. sometimes you canresolder them and they stay.

Power problem


If you don't have any indicators working, you have probably lost your power supply. With no picture and no sound the chances are you have either lost the power supply or blown a fuse. If you remove the cover and look at the circuit board there is a fuse located near the rear of the chassis near where the power cord connects to the chassis. If the fuse is blown, it is advisable to replace your damaged power cord before replacing the fuse. The cord could have a short and this could create a fire. Be very careful when working on any television. Be sure it is unplugged for more than one day to allow the high voltage to decay from the picture tube. Do not touch the picture tube, it still may have some residual voltage and could shock you. If you replace the cord and fuse and still have the same problem, you will probably find that the high voltage transistor is bad and needs to be replaced.

T.v does not make a sound when turned on, and shows black screen


It is very often that the power supply, and or the horizontal output stage have some faiiled components. There are many components in these areas that can cause this problem. This would require proper troubleshooting.

In these sets, if the fuse is blown, there is usualy a much deeper fault that caused the fuse to blow in the first place.
