TV Screen 'freezing' while watching.


Most likely the DMD board is at fault. If the DMD board is failing it will hold the data lines in the set down which will cause it to stay on until you unplug it. The part number for the DMD board is BP96-00249A but I suggest you have a technician verify the issue and replace the board as it requires mechanical alignment after wards. Please take a moment to rate my answer. Thank you.

Samsung T.V. goes on for 30 seconds then no picture


If this is a flat panel LCD tv, this is a sure sign that the panel itself is bad. I have seen this before. Tv comes on works fine then within 5 minutes goes blank.

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.

TV turns itself off after a few seconds, no picture at all


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.
Solutions?
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.

Hope this helps

It's most likely the digital board, Samsung p/n# Bp94-00385a but I'd trace test both the digital and analog first before blindly replacing it - too costly to just guess..
