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.

Good day!

You have a better chances if you have failing capacitors on the power supply section.

Follow this procedure on how to replace the capacitors.

1. Remove the back cover of your TV.
2. Look for the power supply board.
3. After that,look for the leak or bulged on the top capacitors.
4. If you found ,replaced it with the same type,ratings and value.
5. And finally after you replaced bad capacitors on the board,plug-in your TV and power it ON to test if it is OK.

I hope this solution will be helpful.Thank you and good luck.

Hi it sounds like it could be an issue with board that powers the lamp ,it's called the ballast.When you put a new lamp in the ballast has to provide more power ,when it starts to go weak it will not light up.Sometimes you can put your old lamp in and will work fine.Try partstore.com they might have it right there.Hvae a blessed one!

First step in any Sony LCD projector repair is bulb or lamp replacement. Fixes 95% of problems.

Taking apart and trying to measure things without a known good bulb is a waste of time and effort.

New bulb is just fine.
3 blink shows that lamp cover after replacement of bulb in TV is not fixed properly or not seated well in its position.
Put new bulb and carefully place back lamp cover in its position because lamp cover will press tinny safety switch inside that will send signal to system control of TV that lamp is installed properly.
Turn On TV and get vivid picture of Sony.
Thanks.

Green light flashes 5 and then red light flashes 6

Check the fan that cools the bulb. It is directly behing the bulb. It should turn on when the power comes on. It apparently has a safety to protect your tv(and home). mine is in the process of going out. looking for online solutions as we speak.
