    Having problem with my HP-R4252 42" Plasma TV. It will not turn on, quick blue light flash and then it just keeps clicking on and off. I never get a picture. Already have an extended warranty on it, purchase w/TV. Unplug TV to stop clicking noise. Repair man came, plugged TV in. Don't you know it worked properly after being shut off for a week! They say they have no bulletins on this problem. I have to wait till next time and record the color of the flashing lights and how it clicks. This sucks!

Tv wont power on

If you have a light flashing, it might be the lamp has burned out.
Also the instant on power supply may have failed. Hard to tell anymore from description...

My Hitachi 57F710 TV turns off as soon as it turns on?

The model indicated is a DLP which uses a lamp---lamp will not usually cause set right on and then instantly off----takes it 15 seconds or so if lamp has failed.

Also set has led on front that may blink.

If instant it is turned on it goes off----you have a short likely in power supply or elsewhere.
