    I replaced the conversion amplifiers this weekend but still the same problem. My power light flashes 5 times not three like most people with this problem. I was told to replace Ic4011 but I am unable to locate that IC on the circuit board. Thanks for the help.

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!

TV won't turn on when push power button red light flashes


You can unplug the tv for 1 minute and then plug it back in since you have a red light you know it is getting power, also don't plug it into a surge protector when trying this. If the tv still has a flashing red light a service center will need to repair the tv, replacing more than likely the power supply or small signal board.

Panasonic LiFi model number PT-50LCZ70. Have red lamp light flashing on front 2 times. Have tried to turn it on and get no picture and no sound at all. I checked and the fan is running. What now?


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.

I have a panasonic rear projection 53" TV model PT-51hx43G. Just got this bad boy back from my ex wife and when i turn it on the power led flashes 3/5 times and goes dim. I have checked the power and...


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.

The Power Light is Red


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

Panasonic PT-53TWD63, TV will not turn on, Red power light blinks


It is most deffinately a convergence chip issue. The die for no reason. They can be bought online for around $10 dollars and anyone with experience with soldering can replace them pretty easily. I have done it.

PT-45LC12 wont power up


You have a bad lamp. The "clicking" sound you hear is the ballast (lamp power supply) attempting to start the lamp. The warning on Panasonics that comes up on screen does so when the life expectancy of the lamp is approaching. Otherwise your "clicking" sound and the red light on front are saying bad lamp. When you replace the lamp remeber to follow the instruction that Panasinc provides with the new lamp on restetting the lamp timer. This is usually done with the volume down on the TV and the PIP button on the remote.
