3 LEDs in the front blinking.

Unplug the set, pull out the lamp module (not all the way - leave it on the track) and push it back in.

Power issues (Tv not turning on) were typically due to faulty ballast. While the TV reports a bad lamp it is the ballast itself causing the issue. Samsung is well aware and will replace both the ballast and the lamp (since the lamp can be prematurely aged but the bad ballast). After replacment most people stop having issues.

I had the exact same problem with my rice cooker. I took the lid apart. There was a broken wire because of the constant friction of the hinge when open and close the lid. After I soldered it, it started to work again.

Maybe a problem in deflection section. If there is a problem in these section the micom ic is trying to protect to continue anymore short circuit. Or there is a leakege in power supply section. This could be fixed by service technician only. Better to call nearby service people.

Television will not come on after low voltage surge


Good day.

Check on the horizontal output transistor, vertical transistor, and loose contacts along MICOM and system ICs.

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.
