Question about Pioneer SD-P6091K TV
I recieved a SD-P6091 projection tv from a relative. I don't know how to describe the problem, but i will do my best. When the tv is turned on, the pic shrinks down into the middle third of the screen and bows a little bit. I've removed the front panel of the tv, and started fiddleing with stuff, just pressing on it a little. The whole panel on the left side, if pressed down a little will fix the picture untill the set is turned off. There is a transformer on that panel that clicks whenever I press on things and the screen gets back to normal. Also, if i pull lightly on a set of wires connected to a vertical panel on the board on the right side the screen will go normal again. Any ideas as to how to fix this problem? I really love this tv and can't really afford to get another big screen tv. can someone help me with this prob?

it is the power supply board an know problem with pioneer. If you have any soldering experience you can remove the powersupply board and resolder the tracks and as many parts as you can. I had the same problem and not the power supply works great. You will soon have other problems like pic and sound going intermittant where you have to hit the tv to get it back on. more solder problems on video main board. best of luck

The problem you are describing is known as a pincushoin problem. I'm a bit surprized that you only see it on the 1080i signal though. I've inquired at my Pioneer contact about this and will update this soon.

I had the same problem, try running the TV on Mute, if it is a bad solder joint the sound can vibrate the solder point and trip the relay, if the TV doesn't trip off with the sound on mute then it is probably the big power transformer's solder connection needs resoldered. sound vibration from those big pioneer speakers may loosen the solder joint over a period of time because the transformer is heavier and bulky and vibrates a lot.

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.
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
