SOURCE: blinking red light on tv over power button after pressing power on

First thing I would do is replace relay. If relay is sticking open then replace and there is a diode in front of relay replace it to. Not least the caps around it.

1)all TV's I service get the chassis pulled for good visual inspection and soldering any/all suspect connections,esp. any

active device mounted to a heatsink.

2)Check horiz drive circuit for weak capacitor.

3)Let me know if you are still on it.....T.

SOURCE: TV turns off and power light blinks unpluged andd still does it.

Likely to be the STK convergence chips causing a protection circuit to switch the TV off. Have you got any onscreen convergence problems (i.e, colour fringes)?

Toshiba 55H70 55" Take the back off and pull the HV power board and check all the solder joints, seem to me that you has a cold solder joint. check it out be carefull with high voltages.

Sunbeam SLP3310-UM shuts off after 2 minutes. I unplug it and hear a relay clicking after a couple of minutes. Replug it, and shuts off again after 2 minutes. It worked fine last year, not this year.


It's broken --- call Sunbeam customer service (888) 264-9669 and have your receipt and serial number ready. They are aware that these have faulty switches in them.
