Maybe time to check voltages there---problem has to almost certainly be power supply related or on the main board with the control circuitry.

TV will not turn back on after it's powered off


The capacitors on the power supply need to be replaced. When you take apart the TV, and then remove the power supply (it's the section that the power cord goes to) and open it up. Look for the little can capacitors and see if any of them are bulging on top. That is the sign that they've blown. Replace the big ones (about 5) for about $5 in parts. Reassemble and test by turning it on. Search for YouTube video on how to replace capacitors.

Sharp primo tv 21 inch have power but no display?


You may have one or more capacitors blown. This is a very typical problem. Google "Blown TV capacitor" to see the pictures of a (blown) capacitor so you know what and where to look inside the TV.

I turned my tv on, it then turned itself off, there is no red light, have turned off from socket but still nothing.


Hi!
That's a clear indication that you have a bad power supply in your TV.
If you know how to DiY...I suggest you open your TV. Locate the power supply section, it is where the end of the power plug is connected. Replace all blown or bulge or leaked capacitors with same value. That will fix your TV problem.
The hardest part is to disassembling your TV cover, cause you will need to pry off the snap in lock at the edge of your TV.

Power supply board should look like this. Examine the capacitors in the board
power%281%29.jpg2_23_2012_11_31_16_am.png

After replacing blown capacitors...it should work again.

Things you will need.
1. A plastic flat end screw or any object with flat ends....to fry off the cover
2. Soldering iron.
3. Soldering lead
4. Soldering pump.
5. Flat and Philip Screw
6. Replacement capacitors (of same value with the blown one) that you can buy to any electronics store.

Hope it helps

Sanyo tv keeps turning itself off any ideas?


You probably have blown capacitors on the PSB-power supply board. Recaping with new UF caps works 90% of the time. The set turns itself of into a fault protection to keep from damaging more components internally. A few bucks a soldering iron some solder should do the trick.
hope it will help you. -monchi

Playstation 3 turned itself off while i was playing a game and now every time i turn it on it keeps turning itself off after like 3 sec


It sounds like your PS3 overheated and is now shorting out. Try removing the power from it completely, and let it sit for about 4 minutes. Plug it back in. If it doesn't straighten out, you will likely need to contact Sony support for an RMA- it sounds like yours has developed blown capacitors

SyncMaster540N keeps turning itself off while the power LED is still on. Then I repeatedly turn it on and off and it eventually stays on.


Look for bad caps.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed SAMSUNG monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Monitor turning itself on and off


If you can open it... check the capacitors in the power supply section. Blown, bad or bulge capacitors need to be replaced with exact value. If you have the knowledge and the right tools then you can fix it by yourself. Otherwise bring it to a repair shop
