First, if the convergence chips are bad or shorted the set will shut down and the power light will blink three times in a sequence--if no three blinks I would suggest another possible problem common to this set.

Before the set shuts off do you see anything at all on the screen after a minute or two? A strange band of noise from top to bottom on the right side? The more information you can give me the better the chance I can tell you exactly what is wrong---I have fixed hundreds of these sets--

I am here to help--give me all the information you can

Roland,

STK392-110 is a Convergence IC that is responsible if there's NO picture but there's a sound coming out from the TV.

BUT if there's no picture and no sound, then you need to check or replace the Inverter board and not the convergence IC.

Check the link below so that you could see how the inverter board looks like:

Have a great day!

Trying to replace lamp in HDTV and having trouble. Does not function correctly after putting in new bulb. Boots up and then visuals go black and the green power light keeps flashing. Help?


Panasonic DLP TV Bulbs

Make sure its an original Osram or Philips bulb inside the housing. If its a cheap lamp it will act this way. If it is an original lamp, then you may have a power supply issue. It shouldn't affect your TV but you may want to try resetting the lamp timer by following the instructions that came with the lamp.

TY-LA1001 Timer reset

While pressing the VOL- button on the projection display, hold down the number 0 button on the remote control at the same time for more than 5 seconds.

My panasonic th-42pwd8uk tv wont power on. When I press power it clicks to turn on then clicks again and the screen never shows up. No red lights no blinking lights just a solid green light.


Check the capacitors and replace the power components. It is an easy fix if handy with soldering electronics. Tv Repairman may charge less than $100.00 bucks to fix it !
Good luck

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
