(3) 4 amp 150 volt fuses (slow burn), and (2) 10 amp 250 volt fuses (ceramic), all replaced. $5.50 worth of fuses DID THE TRICK. Radio Shack has them both. If you can't find a 4 amp 150 volt, 5-6 amp up to 150 volt fuses work just fine!

SOURCE: Power problem (switches to standby)

its the problem of the ics on the main power supply board

Do the IC heat sinks get warm??

If they do not, check fuses F852 - 2AMP, F853 - 1.25AMP, F850 & F851 - ALL 5AMP on the power deflection pcb. THESE ARE NOT GLASS FUSES. They are usually about the size of a 1 watt resistor and either green or orange in color. They are soldered in. The nomenclature is printed on the component side of the board. They are all about centered on the opposite edge of the PCB as the high voltage transformer.

If you have cleaned up the mess you describe you most likely have one of these fuses blown.

if dont have any technical knowledge its advisable to call a technician as it is worth getting it fixed.

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.

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.

Samsung HLP4674W - changed bulb - still no picture - lights flash

If the lamp has been replaced I would think the Lamp ballast would be most likliest followed by the color wheel and then the Digital board. You can get any part needed for your model at just leave them a email they respond quickly.

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
