Re: Power light stay on

Sounds like you may have a sticking Relay S901 on the power board. Tapping the Relay may Make The Light Go On And Off. The relay part number is FJ00142 if you can find someone to work on the set for you as it would involve soldering in the new part. The number on the relay may be ALKS329 with the former part number being the Hitachi Part number.

Won't turn on

Possible there is a problem with your power button try to check it if it is still functional. Read light means standby power meaning your TV still working. If you cannot do it by yourself fixing it try to bring your TV at your nearest TV shop to check the power button.

Hoping for your kind approval to make my rate Solved for this problem.

Best regards,

Magnavox 50ML8105D/17. We moved and the tv worked fine and now nothing. Just 2 red lights. Temp and Bulb. I replaced the bulb about 6 months ago. all I did was move.I carried it myself. I have checked and...

My magnavox died due to cheap capacitors on power supply board, a common problem for magnavox tv's from wot i found on net!
I replaced a 2200uf 10v electrolytic capacitor and it works now:)
My tv would take a few atempts to turn on and finally would not turn on,light stayed red!
i recommend visually checking for bulging or blown capacitors on power board, if it all looks good, try warming the board with a hair dryer, this might be just enough to get it to fire up, so at least u know the prob is in that area.
I looked for a 2200uf capacitor near the low voltage output from board n replaced it, got lucky first one, I was expecting to replace all the low voltage electrolytic capacitors.

The Power Light is Red

yeah, should stay red when unit is turned off, indicating there's power but it's doing nothing.

Per user manual:
Solid red - power off (standby mode)
blinking red - power off (now cooling)
blinking green - power on (preparing to light lamp)
solid green - power on

Need Help big screen turns on thens goes off

a tv has two components, firstly a power supply produces high voltage to trigger a line transformer, in turn a transformer produces smaller voltages. firstly check if the ht is constantly been produced from a supply, if this is there than go to a line transformer, and check voltages at the output.
