Probably started as a bad solder connection but if it's blowing fuse FU106 now, you're probably in for a new set as that usually means your convergence IC's are bad along with a pair of darlington transistors that's mounted to the heatsink nearby. With the age of the set it may not be worth the trouble. If no fuses are blowing, you could still have a bad solder connection near the Switched Mode Power supply transformer. If that isn't it, you could have a bad High Voltage Block and you may end up having to replace the deflection board as well thank you Pioneer.

The projector is starting to go out in it. Depending on your financial situation, you can take it to a shop to have it looked at, or replace the TV. Depending on how long this has been happening, the Pioneer projectors usually last about 100 hours once this happens before they burn out completely.

Pioneer SD-P6091 Projection TV - TV turns off by itself


I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

50" Pioneer TV blacks out and has shadow on the bottom third


yes it is worth fixing.if you r getting it repaired for the first time.
but you will have to wait for some long time to get it repaired as the tv is very old its very difficult to get the parts for reparing it.

the problem what you r facing is the problem of the convergence in your main board of the tv.
it has to be repaired.
i will advise you to get it repaired as it will work.

for doing it your self you can try clicking this link and following the given instructions in it

Pioneer SD-P6091K problem with turning it on


Is this set several years old, and has it been good till now? There is one on the internet, 8 years old for sale with the same symptoms as your friends. There is an internet site `tv-forums.com. Presumably you have already looked with the back off. Make sure there is not a build up of dust, which will cause overheating. If it has a 150 watt UHP lamp, or similar,(expensive!) it may need replacing. The lamp must be cooled by a fan, so make sure this is srill working. There should be a thermal cutout which automatically resets.
