Panasonic PT-51HX43G no power, red light flashes

Tv making and have clicking sounds as tv shutdown as lights flashes?Yes.The board that call the Ballast board might be dying and dead soon.This Ballast board job responsible only are to ingnite the tv projection lamp only.

Try to power it up with the remote control. When you hear the relay's click, see how many times the red light flashes. This will tell us what the fault is.

theres a problem on the board of the tv set jsut go back to the service center for further check up of of the technician of the panasonic un plug the tv set for it can cause further damage

After the red 2 flashing starts, press the power button on the front of the TV and hold pressed down for ten seconds.
You will hear a faint click comming from the back of set.
After 10 sec release the button and wait 10 more seconds then press the start button and release right away.
The green light flashes and the bulb attempts to start.
I found my picture will turn on on the third attempt of the bulb restarting.

When you do this and the room is dark you can see the bulb attempt to restart, My bulb has restarted on the third restart every time.

(note: The three start attempt happen after I do the button pressing
1 time and I do not need further button pressing restarts.

I think panasonic needs to let us know what the problem is.

I called Panasonic and they told me to plug it into a wall plug by itself.

I have it plugged into a multi plug adaptor now and have not tried this yet.

CK hori out put Transistor, next to or behind that part is a small blue capacitor high voltage 2k volts see if it has burt pin hole if so replace it also resolder convergence plugins and FBT.Your STKs could need replacing they are big black ICs will have part number on them if 110s use 180s Call Mats for parts 1-800-628-`1118

If light blinks twice then your bulb is bad the bulb is under warranty for five years but only three to replace, call Panasonic

count the led blink as thats an error code. If it blinks three times its indicating the convergence Circuit has failed. Let me know the actual blink number and I will assist you.

maybe stupid but try to plug-unplog from power outlet.. does it make any sound? kliking sound? if nothing helps than your starter is gone.

yeah, should stay red when unit is turned off, indicating there's power but it's doing nothing.

Per user manual:
Solid red - power off (standby mode)
blinking red - power off (now cooling)
blinking green - power on (preparing to light lamp)
solid green - power on

I have a Panasonic PT53TW53G projection tv that had the same problem for power .A terrific person gave us wonderful advice and it fixed our tv! We were told to replace the IC conversion amplifiers. On our model they are STK392-110 (your's may be different). We ordered the parts from www.electronix.com and they were only $12. for the two parts. We also had to purchase a soldering iron and de-soldering vac for removal/replacement of parts. Good Luck!
