    My Samsung plasma is 8 months old, and the screen goes black every few minutes, and the sound goes with it. It only lasts a few seconds then it comes back on again. The blue power light remains on, and does not flicker.

    This only happens when tv is in DTV mode. It never happens in analogue mode. Can you help???

The problem is the internal power supply module has gone bad the first sign is usually the pip if included stops working... well open your lcd monitor try not to damage screen for those who have carpet you may want to use glove to keep your self grounded from cause any other damage to components the boards are usually sperate unit in the new models unplug the powersupply unit

(you can tell because the outlet that the cord connects to will be locate on this board)

once remove locate part number and call manufacture to order part another method to by pass manufacture take unit to your local tv shop it has to be a good one because most only buy new parts but ask them to test and replace bad part of power supply should be faster then manufacture send replacement part

no manufacturer want you to fix they want you to buy new units again

42 inch Samsung DLP TV shuts off by itself. I can turn it back on and sometimes it stays on and other times shuts off within seconds. Some days it stays on all day without a problem. Other days it shuts...


I bypassed the safety switch (it was bad) and vacuumed and blew out all of the dust. So far with this set, 3 years old, I have replaced the bulb twice,it exploded both times, and the color wheel which also exploded! We love the picture but the next time it goes out, it goes out to the trash and I will purchase a top of the line LED/LCD set. No moving parts!!! Samsung designed and manufactured a whole bunch of lemon sets and will not admit it. I have found several hundred complaints about their DLP sets and only a few on other brands.

Tv shuts off after 6-8 seconds


capacitors in the power supply, they all should be replaced, before it takes out the rest of the ps. there are companies that rebuild them if your tech is not up on repairing them.

SAME HERE I HAVE A 52 INCH SONY HDTV AND SHUTS OFF CONSTANTLY


Is the tv and receiver in the same cabinet...or an area where the heat from one can affect the other. If so...you may have overheating. Also, be sure that airflow around the TV is good and that any air paths are open (enclosed cabinets can be bad news)

When turning on the TV, I hear a banging/grinding sound.


Hi,

If you hear a grinding,whirling,spining or buzzing sound, that sounds to me like the COLOR WHEEL,the reason for that is because your color wheel spins at 5,000 rpms(revolution per minute) and something that modifies the balance of the disc can cause different things,Unfortionatelly the only way to check that the color wheel is working properlyis you need to check it out physically

I did some research and I found the color wheel at DM;http://www.discount-merchant.com/Samsung-Replacement-Color-Wheel-HLS-HLT-Series-p/samsungcolor_wheel_bp96-01579a.htm?CLICK=52978

Please keep us posted.

Hi, Lamp of TV getting weaker and requires replacement. This shut off by itself will increase day by day until you put new lamp in TV. Always Buy Sony original lamp and avoid aftermarket/ cheap lamp for TV safety.

Projection TV keeps shutting down


Good Day;

Sounds like you have a bad green picture tube that has failed. To check this out; remove front speaker grill, remove small panel, you will see three CRT's (pictue tubes) sticking down, remove the little board on the middle tube then restore power. If TV stays on more then likely the CRT is bad but not always the driver on board could also be bad, check voltages.

Good Luck, big IRISH.

Tv shutting off


How many times per second does the POWER led blink? (dont worry about the OPC).

1x per second (constant, steady blink) = bad inverter/lamps
2x per second = bad power supply
3x per second = bad main board

You can buy the parts online and fix if yourself!!

TV shuts off after 10 sec


TV/vcr combo units develop problems in the vcr section,what happens is the cassete assembly draws too much current then the tv senses this increase and it says NO and shuts down,you will not be able to use the vcr anyway because it has a problem and the tv will continue to shutdown until the vcr is repaired,I have seen combo units with the tv working only as long as the vcr is not use.Remove the light you have in the opening and hope the tv works fine by itself.Adding a light is not safe.I hope this inf.helps somehow.Good luck
