Question about Hitachi 53UDX10B 53" Rear Projection Television

2 Answers

Power light doesn't shut off.

I have the 53udx10b.  I turn the power off but the power light stays on.  I tried turning off the power strip overnight and turning it back on the next day.  Unfortunately, the minute I turned the power strip back on the power light lit up again, even though the TV was off.  TV seems to be working ok but the problem concerns me that something may be happening that could permanently damage the tv.  I spoke with a Hitachi rep and they said it was just an LED problem, I tend not to trust the off the cuff advise given by customer service reps.  Any ideas on a fix for this problem?

    53UDX10B TV will not always power off and almost always comes on by itself in the middle of the night. Have plugged it into a power strip that I turn on when I want to watch the TV and off when I'm through. This is a real hassle.

Same problem just happen to my Hitachi and tech guy just left and fix it it's the relay he first gave a little tap on it and it was ok but he ordered the part and will come back to replace with the new one and voila like brand new.

You're right. It's not only a led problem. Efective. the tv doesn't shutt off due to defective relay S901 in primary power supply. It's a 5 volts ordinary relay, replace it and it'll be fine.

Does it work though? If the light is staying on after you cut power then maybe a genie is living in there :)). Other than that it could be a bulb with bad or loose connection. I do know those touch pads behave weird if there was a power cut/surge. Mine did that bit it still works. I'm just waiting to see if a light blows or if some other short happens. Anthony

53udx10b hitachi rear projection big screen. replaced convergence chips 2 months ago. Worked awesome. Started having power issues 3 weeks ago. Turn on - kicks right back off. Used to be able to turn...

Sounds like the problem started out with an intermittent solder connection possibly on the deflection PWB unless the power relay has a bad connection or is breaking down under load. If it is not the power relay, I would check the connections under the deflection board - paying close attention to the area from T701 and T752 including the Horizontal output Transistor for a short. You also have a possibility of defective filter capacitors causing the problem as well.

The power does not want to stay on.

TV needs major service, convergence and also the power supply expect to spend around $350.
