Re: Tv cuts off and on.

Sounds like a bad SSB(small signal board) module. Better take it to a RCA AUTHORIZED service center.

The tv wont power on and the green timer light continuously blinks. I have unplugged the the tv and also hit the reset button.

...OK to begin troubleshooting this. Unplug the set and leave for 1 min then plug up and leave for 2 min push the power button and let light blink for 2 min.... now push and hold at the same time the MENU and DEVICE buton st the same time. this is the self diagnoses feature ... the lights should link then pause then blink again... this 2 digit code will help narrow it down. Also have you check the lamp yet?

The tv just turns off after about 5 seconds and won't stay on. i've used the system reset and unplugged it already. no power surge, lightning storm, etc. Ideas?

If reset does not cure it and if after about 70 seconds of unplugging set the green power light stops blinking, do this:

When power light comes on and goes off, on the front of the set press and hold both the menu and input buttons at the same time for at least 5 seconds and RELEASE both buttons.

Power light should blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it four more times.

My panasonic pt50lcx64 will not stay on, sometimes wont even turn on, but when it does, it lasts about 5 min then cuts off and the yellow light blinks 2x every 5 sec

Try typing your model tv along with the words "trouble codes" This could be a code 22 or a 2. Sounds like a bad connection or bad component failing such as capacitor or resistor. The tv may be shutting down as protection against what it senses as a power supply failure.

When the power light comes on and then goes off perform the self check feature the model you indicated has:

On the front of the press and hold both the MENU and INPUT (DEVICE) BUTTONS both for at least 5 seconds and release both buttons.

The green power light should blink a two digit error code--most common is 2 blinks, a pause and 2 blinks.

Let me know what error code you find and I will tell you what it means.

We plugged in the tv and hit the power button the green timer light blinked for about a minute. We hit he power button and it stayed on for about 5 second and turned off. We just bought this tv used and...

This is a common problem with this kind of tv. When you give the unit power the green light will blink because it is telling you that the projection lights are warming up. Sometimes it will take up to a minute. When you hit the power button again after only 5 seconds it told the tv to power off. I hope this will help you out.
