Clicks repeatedly when turned on, red power led flashes, chimes sound twice and then it repeats, over and over and over, eventually it comes on. Green light occaisionally flashes at upper left corner, but hasn't become anything more than annoying for now. Purchased 11/08.

I'd look at bad LED backlights

1. Turn on the device (for example, DVD player) and, if needed, load media (for example, DVD).
2. On the remote, press a device key (that is, VCR/DVD, CBL/SAT, or TV). 3. Press and hold P until the red LED blinks twice, then release.4. Enter the first four-digit code for your device.
The LED blinks once as each digit is entered. If the code is correct, the LED blinks twice.
NOTE: If the LED does not blink twice, repeat steps 2 to 4 and try entering the code again.
5. Aim the remote at the device and press Power (or Play, if it does not have a Power key). The device should turn off. If it does not, repeat steps 2 to 5, trying each code for your brand until you find one that works.6. Repeat steps 1 to 5 for each device you want to control. For future reference, write down each working device code in a safe place.Code search Method

1. Press TV once.
2. Press and hold P until the red LED blinks twice, then release.
3. Enter 9 9 1. The LED blinks twice.
4. Aim the remote at the TV and press Power. The remote sends IR codes from its library to the selected device, starting with the most popular code first.
5. If the TV responds, go to step 6. If the TV does not respond, press CH+. The remote will try the next code. Continue until the TV responds.
NOTE: Press CH- to try the previous code.
6. To lock in the code, press P once. The LED blinks twice.
7. To search for other device codes, repeat steps 1 to 6, substituting the appropriate key for the device.

1. Press the "DVD/VCR" button on the remote.
2. Press and hold the "SET" button on the remote until the red LED blinks twice, then release the button.
3. Enter the 4 digit code for the VCR. (Red LED should blink twice after you enter the code.)
4. Aim the remote at the VCR and press power. The VCR should turn on. If not, try another code until you find the right one.

turn tv on picture comes up 2to3 seconds later tv blacks out then stand by red light flashes 4 times in a row repeatedly..can not turn on or off when stand by light starts flashing but before tv blacks out you can turn tv on and off repeatedly and picture and sound work.You have to unplug power cord for 30 seconds after stand by light comes on to get tv to turn on.

Sounds like power supply issues, if your able take the back off and see if the voltages are correct, if they aren't replace the PS

When the set ends up flashing the LED, it should be a repeatable count. Can you please report that count here? Also, since the set eventually works, I'd suspect a bad connection or a part that has changed value over time. The blink code will help to narrow down the offending circuit.

is this a lcd projection or just tube projection

check for a bad cap ,relay sound ok or could be a bad solder connection in the power supply at the regulators

Yeppers. Sounds like the standby power supply has a bad capacitor in it and the regulator Ic is defective. These parts should only be replaced by quilified technician as there is very high voltage inside these sets. Good Luck
