The TV will not turn on

thats usually an error code. How many times does the light blink?

The blinking power indicator is actually identifying the ircuit which is stopping the set from working. How many times is the light blinking? Please respond to this sme post for assistance.

your bulb is burnt out,have to order new one, big problem alot for me anyway

The power light keeps flashing and the tv won't turn on. If you unplug for a minute and hit the power button it sound like it is coming on then it shuts off and the red power light flashes slowly. The TV is a Panisonic 1080i HDTV, about 6-7 years old.

IC4511 isnt comunicating. Replace the DG board

tv will not come power light just flashes red

thats the error for the convergence ICs You will need two STK392-110 Convergence ICs you can get replacements at the following link.

By the sound of it its a dead power supply im afraid :( It is very common for them models at that age very common... it may be cheaper to fix then buying a new one but ill let you decide that one but yea theres hundreds of people that have the same problem with them panasonic's bummer dude :(

The power led blinking is an error code if you can reply to this same post and let me know the number of blinks I can assist you with what it means.

3 blinks corresponds to convergence ICs
