Before going to inside boards check external power cables and tighten them if loose.

My tv is keep turning itself on and off and my remote has randomly stopped working, ive had the plug out the wall the past 6 hours nd no joy, any ideas? I've put new batteries in the remote 2


Sounds like a power board issue? Dry joints on the main board? Capacitors may have issues.? I would not go opening up the TV if you are not aware of the potential dangers.

Samsung TV model LN32A450C1DXZA, after turning the TV on it will turn itself off shortly after and then turn itself back on shortly thereafter. Then it repeats that several times before staying on.


Hi there,

If the tv is still under warranty, this can be repaired at no charge.

However, if not under warranty, you will need to have the CAPACITORS on the main power supply circuit board tested (or replaced).

The capacitors responsible for the power supply can sometimes fail - open the back panel. If the capacitors on the main power supply board look too fat, or signs of burning near the solder joints, then you've found the problem.

Hope this helps.


Cheers,

Scott

TV randomly turns itself off and on


This issue is related to the TV's main board not seeing constant A/C power to unit so the board is turning off the TV.

When the TV's main board see A/C power back to the unit, the TV will try to turn back on.

This issue could be a loose power connection for the TV or a failing part inside the TV. Do other electrical devices work when plugged into the same wall outlet?

Try the following:
1. Remove the cord from the back of the TV and reinstall it (perhaps it's loose going into the TV and was not installed correctly).
2. Try putting the cord into a different wall outlet (perhaps it's not a good outlet).
3. Try using a new power cord for the TV. (Any matching cord will work for testing)


If the above did not resolve the issue, then it could be the switch mode power supply and or the main board inside the TV. Both items are easy to change out.

I can look up the LG part number for you.

Samsung 2006 56" HLR5688W DLP TV Right half of screen turns black. Left side normal picture. Corrects itself when set is turned off and back on. Randomly occurs - sometime picture is ok for half a day...


Possibly a bad light tunnel assembly if the part is only a shadow effect. If not then probably a bad DMD board. The DMD board is part of the light engine but needs to be replaced by a technician.
