    I think I may have forund it. There is a blown fuse, it takes a lot of searching as there is about 6 fuses you must check. I need to pick up a fuse but i'm sure it's the problem.

On my pt-50lc14 hdtv my screen is stuck on this message, 5v eeprom), 3.3v (gc2), tv-factory mode


Have you tried any of the reset commands?
Try these....please let me know the result:

Method 1
1. Unit power must be ON and unit must be in STOP mode.
2. Press and hold [CH UP] and [CH DOWN] ON THE UNIT for over five seconds. The unit will turn off.
3. Press [DVD POWER] to turn the unit on.

Method 2
1. Press [STOP, TUNE MODE] on the main unit and [>10] on the remote control at the same time for about 3 seconds until the message "Initialized" disappears from the television screen.
2. Turn the unit off and on again.

Method 3
While the unit is off, press and hold [VOLUME +], [OPEN/CLOSE] and [POWER] on the main unit at the same time for more than 5 seconds.

Method 4
While the main unit is on, press [POWER] on the main unit for more than 4 sec. (All the indicators will blink twice when the main unit is reset.)

Another possibility is to unplug the power cord......wait 30 minutes and plug it back in, possibly repeating the steps above. (Method 1 should reset the unit but maybe trying each of them may be necessary until it is reset.

The message appears to be one that displays when the unit is in a setup mode.

Thank you for your reply.

Have a 55" pioneer rear projection tv, was working great, turned it off and when turning back on it comes on for a split second and it shuts off


Take the back of of your set. You should see if there are leds on the circuit boards that light up when you try to turn on set. Use these for reference.
If only D146 on the power supply lights up then the problem is the power boar.
If D1503 lights up then the problem is the audio circuit on the amp board.
If D2614 then the shut down is due to lack of vertical deflection. It could be caused by a defective amp assy or convergence control assy. Checj for convergence drive signal at CN2302 pin 1. If missing, IC2308 on convergence control assy is probably defective. You can confirm by checking blanking signal input on pin 1 of IC2308.
Good luck to you.

I have a problem with the pioneer elite pro hd510. it only play for 45 to 50 minutes, than i will have to unplug and plug it back and it does the same thing all time. i love this brand, i just want to know...


I have the same TV and the same problem. Mine would play for a few hours then "pop" and power off. I had to turn main power off, let sit for awhile then it would play again. My local repair place came out and installed new power supply but that wasn't the problem. Had to take set to the shop where they found I had a bad amplifier board. It's on backorder with Pioneer.

Set won't stay on, won't turn on


Sounds like a capacitor on the power supply is bad. Easy fix.

your set was going into protective shutdown. Probaly a leaky diode that was raising voltage that triggered the shutdown circuitry.Toshiba has good service info available to trubleshoot the power supply and shutdown circuitry. let me know if you would like me to post a link on where you can get this troubleshooter manual .

Rear projection tv wont stay on


It is a great chance Jeff that your Power Supply Board (specially the FlyBack) could not hold the voltage requirement to let your TV set on. When local Power Utility supplier is shutdown for whenever reason, this kind of situation occurs. Voltage spikes, voltage outage, voltage drop and dimming are common things. You could replace the FlyBack and then check out if the TV stays on. This will cost you from $60.00 to $80.00, but it will not guarantee that it was the only component that suffer the shutdown. I really suggest you to replace the main power board (from $175.00 to $250.00 - with core exchange). It is something you can do on your own and I'll recommend you to check on the following site (my favorite to buy parts): http://www.vancebaldwin.com/ SithPitt
