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.

I have a 27" RCA TruFlat TV. Recently the picture


Something has definitely gone wrong. When picture fails, generally the audio will still play; but since the set is shutting down completely after a short time - it is going to more involved.

Firstly, anything can be fixed. The questions to ask are: 1) At what point do you stop spending money to repair a device that is XX years old? 2) How much would a replacement / upgrade cost?

Given that your set is an older SD (standard definition) with an old analog NTSC legacy tuner, it may be worth while to make the move to a digital HDTV. The picture quality will "blow away" any SD version of the same image / program that your old TV displayed. Unlike several years ago, the HDTV has come way down in price, too. A 32 inch, wide screen HDTV price starts at just $235 as results shown by a search in Google. In order to view HD signals, you'll need either 1) a plain UHF/VHF antenna (and local broadcasters in range), 2) HD cable TV service or, 3) HD satellite service. Cable and satellite providers offer SD service and for slightly more, HD service. Most people are not happy watching SD signals on an HD display - so you'll probably want to change the level of service if you're not using an antenna. Old DVD players only send SD signals, you might consider upgrading to a Blu-Ray player. Blu-Ray players provide SD and HD signals - depending on whether you insert an SD DVD or an HD Blu-Ray disk. The Blu-Ray players, like the HDTVs, have also dropped in price significantly.

See if you can find a place that provides free estimates. If not able to locate, find someone that will apply the cost of diagnostics (ask what the diagnostic fee is) to the total repair charge, and decide to either fix or replace.

I hope this helps and good luck! Please take a moment to rate my reply - thank you.

mcdevito75 here, One year old, most likely the factory Battery and at 1 year old the battery is old, who knows how long the battery was in the watch before you bought it 1 year ago?? The battery is the first suspect. Look for a small watch repair shop in your area for a new battery first.

Insignia lcd 37''powering off and right back on by itself!


Hi Ed,
Since the TV is less then a year old and still under manufacturers warranty, I would suggest to take back to the vendor to get it fix because this LCD behavior is not going to get any better.
The failure on this TV is related to a power supply in most cases if the TV is turning OFF by itself or needs to be unplug to let cooldown and it works afterward.

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

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.

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.
