My TV had the same problem. I called Sony yesterday and they told me to reset the TV. I did so yesterday, and it seemed to work. Here is the transcript with instructions: Please turn ON the TV.
While holding down the RESET button on the Remote control, press the POWER button on the TV.
The TV will turn itself OFF, then back ON again.
Release the RESET button.The TV will go thru the initial setup, and should work normal.
I had a similar problem with my Phillips 42 in. LCD HD TV.
Here's the problem. The Power Supply Board. I opened my TV
up(warranty was up of course) and found several bad capacitors.
Phillips and several other companies were sold capacitors that although
were highly rated failed within 5 years because of a lack of
preservatives. All sorts of electronic equipment is now being effected
due to these defective capacitors.
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.
I have a Samsung HLP5474WX/XAA. The ballast was replace 2 months ago. I just installed the lamp, i notice green flashing occur on the LAMP when i turn it on. The tv takes 10 to 15 second to turn on the picture, the sound as soon as i power up i can hear it. Any advice??
I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
