    Hi, if the TV is shutting down after a while you need to test components that are affected by overheating or that can fail when operating at certain frequencies.

    Test the power adapter, and the STKs on conv. board, this can overheat.

    Also a faulty jungle IC can give you weird problems of this kind.

    Check also the ceramic filters on ir circuit, they can fail at certain frequencies and cause the same.

    Test also all solder joint, in case the fault is related to a bad solder joint and TV is turning off because of vibrations breaking a contact on a cold solder joint.

After running for a few minutes the picture abruptly shuts off and turns back on for a few minutes then shuts off. This cycle repeats itself over and over.


Make sure the top and back of it are not dirty or obstructed, it sounds like it is overheating and shutting down to protect itself. Or your main power board is going out.

The power supply is failing. Your TV is able to start but the power supply can't continue operating and shuts down.

It sounds that the voltage output from its internal power regulator board is not proper. Check it.

Mine does the same thing but it also shuts itself


These usually have a good Warranty as this is a Best Buy product. They would be sure to fix it under the waranty if you take it in. They would be able to give you an estimate of repair if you take it in also. They may have a flat fix fee or possibly an hourly fee along with what the power supply or bad part cost.
Usually a power supply problem. 42" is still an expensive TV to replace. May be best to repair.

Picture & sound shuts off


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

As far as fixing goes, you might as well get a new TV... Unless its a LARGE EXPENSIVE HOLY $%^# TV, It will cost more to fix, than to just buy a new one, unless its under warranty, which being an older model as that (or so im reading) It may not be covered.

Try unplugging the TV, and while unplugged, hold down the power button for a full minute (yes, with the plug NOT in the wall) after a minute, plug it back in, and try. Its a hard reset. If it still does not work, and you've tried different outlets, It's probably a repair issue, and you'll need to get someone to fix it, or just junk it :-/
