I have a Sony wega old style tv and the standby

The reason that that TV does that is because it needs a new lamp there's a lamp that can be installed in that TV you can search Amazon for the part you need and that should correct the problem especially if you have sound and no video

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.

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.
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..
