SOURCE: tv switches itself off then back on again

It seems that the back light is malfunctioning or needs to be replaced the fact that it turns off after a few seconds indicates that is getting over heated. All LCDs, Plasmas and Projection TVs come with a shut off switch witch will turn of the monitor when a spike on the temperature is detected this is to protect the system from overheating. Now before you think about send it for repair; is it well ventilated? Does air circulates around it? Good luck!

My Samsung 933hd turns itself on and changes Chanel


Sounds like firmware is corrupted. If so a firmware update is necessary. An other possibility is faulty front panel control board. Any defective microswitches at it might have damaged [strucked] or so. Check it too. Do a hard reset to this set, and check. In most cases, a software bug will be corrected if any. Contact any service technician. There are two types of reset to TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.

This is a power supply problem. If the set is under warranty, exchange it.

If you warranty is expired, you can take it to a repair shop and get an estimate to see if it is worth fixing.

My tv keeps losing the picture, i can still hear the sound but no picture after i turn it off for a few minutes it will come on again.


Overheated semiconductor circuit. Maybe due to moisture condensation. Use a fan to cool the back of the tv?

Samsung T220hd Firmware upgrade problem


Cheers, will do in future, just thought i'd re-post to try and get an answer.

Solved the problem the same way suggested above, strange how samsung know about the problem but yet still allow the user to change the firmware.

A master re-set for this model incase it's of use to anyone is info, then menu, then mute then power on the remote in series (not simultaneously as suggested by samsung support).

On a better note, samsung support were very helpful and the free of charge collection delivery service is very good.

Tv switches itself off then back on again


Hi.

If the tv set is still under warantee get it sorted before gtee runs out.

The problem is caused by cummunication error between ATV Micom and DTV Micom.

To correct this problem requires going in to service mode to make changes & updating the DTV firmware.

This will need to be done by a proffesional.

Need help


ensure the tv is in analogue mode, not dtv and turn it off. with the remote: press info then, menu, then mute then power. these buttons need to be pressed sequentially not all at the same time and in quick succession. a menu will appear on the tv. navigate to the reset option and press the left arrow key on the remote (or press the enter/ok button) the tv will reset itself and turn off. turn the tv back on & it'll re tune all its channels. DTV should be working again.
