Only when a device is sensing a problem, it will shut down the normal working, to prevent further damage . It also could be a problem in the power supply, like a bad soldering or other bad contact, only showing when that part become warm or even hot.
In both cases you should ask a tech or bring it to a repair shop. When it is still in warranty, call a Samsung certified service centre close to you.

Sound and picture go out after about 3-4 minutes. Then com back on after a few seconds then go out again and not return. What can this be?


Fault to its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

The tv has no picture but sound can be heard. how


Try connecting a different device to the TV and check. You may also try changing the cable to connect the device to the TV and check. If the issue persists, try resetting the TV to the factory settings, then try power reset. To power reset the TV, please disconnect the power cord for a short period of time (approximately 1 minute). Then, reconnect the power cord and power on the TV. If the issue still persists, then service may be required.

Samsung HP-4252 screen goes black


I have the same problem, and it will get worse. I have read and seen video on youtube, stating that it is capacitors on the power board, that need to be replaced. I watched the tutorial video it seems pretty easy, I am going to try it this weekend. Will update.

Samsung 32 lcd tv backlight off after 4 sec. audio ok


If your TV is staying on and you hear audio after the picture goes dark, then you have a problem with a CCFL or the inverter circuitry that drives them.

Most likely an inverter problem.

Like a bad xformer (usually fogged up plastic wrapper)

Or a bad cap (bulged, swollen, cracked)

Or maybe a shorted IC or transistor (test for short circuit between the different pins of the device)

No Picture No Sound


I think you have a short somewhere inyour set most likely the horizontal output transistor which may have shorted by the high voltage transformer going bad. The faint ticking sound that you hear is the power supply trying to start but the shorted load won't let it. Stargazer

Blackout problems


It could be the LVDS cable that is connected between the logic main board and the main board, sometimes this cable is too short and comes loose from one of the boards, it could also be a sign that the logic main is going out or the panel itself is shorting out
