Sounds like you have a bad capacitor. Likely overheating. Likely going to need service or replacement.

Google how to spot a bad capacitor. They pop up and get a brown dot in the center. They are easy to spot.

Tv turns off itself


When it have this kind of error is a problem of the power-board.
Anyway you must open it and look at the all capacitors and if are them inflated, if them are inflated must change them.

Good luck!

My monitor is power turn itself every 5 minutes, please advice me the solving methodl


Hello,

It's the problem of overheating in the power supply board of the TV.on the power supply board of the tv there are few capacitors and IC.any of this ic is got short or may be weak.so due to this when you start the TV the current passes from electric outlet to the power supply board of TV.but when the current passes from that weak/faulty part at that time current gets stopped or slow and the board overheats and TV shuts off. this is a common problem faced by many other users too.the possible option to solve this issue is to check the power supply board by a meter and continuity tester and replace the faulty component on the board which is short due to which power supply board is getting overheated.its bit technical job but yes its not at all a costly repair to do or get it done by the technician. for required parts it can be easily available from local electronic hardware shop. Take care in solving the problem.....

GREETING HAPPY HOLIDAYS T.V, COMES ON THEN FEW SECONDS CUT OFF. PICTURE SHOW WHEN COMES ON & SPEAK. WHEN CUT OFF BLACK SCREEN & NO SPEAKING. WHAT'S THE PROBLEM JUST HAPPEN TODAY. TRULY


This is a power supply regulator problem. As soon as one of the resistors gets a full load, it trips the fault circuitry, shutting down the screen and preventing the screen from destroying itself.
It's either that, or there is a fuse that is almost burnt out, so that, when cold the contacts touch and it turns on, but as soon as it warms up, it turns off.

It sounds like a bad power board inside the monitor. Or Inverter board. Unfortunately, there isn't much you can do. (Aside from sending it back under warranty) if it is still valid for that.

Monitor randomly shuts off and computer restarts


After you turned it on and the screen shut off, check the image on the screen by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. This is because of the lamps inside screen. Some of them were broken and it is very easy to replace. If you cannot see anything on the screen, there'll be some problems with inverter board. If the computer shut down immediately after the monitor shut off, it might be because of fault operating system. Check with another monitor.
Thank you,

Dell LCD TV powers on and after a few minutes shuts off by itself


Ok, this is the way how to examine where the problem is. You have to check that you can see the image on the screen by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see something moving, there will be a minor problem. Like me, I can see window image using flashlight and check lamps inside. Some of them were broken. If you cannot see. I would say that there are some problems with the inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or dark spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so.
