Question about Hitachi 53UWX10B 53" Rear Projection Television

2 Answers

My 53WUX10BA Red Power light will not go out

Started a week ago. Red LED power light stays on even when set is off. Don't know if set is on or off when input is turned off. Seems to be taking longer to power up, but that may be my imagination. Everything else seems okay.

Picture is black. sound went out a few weeks ago and now all that seems to work is the red power lamp turns on and I hear a click but that's all. I am not concerned about the picture since it is c


The click is a power relay on the main board and if the red light is on I would suggest looking inside to see if it has more than one relay--follow the power cord into the set----some of these sets have one relay but others have up to 3.

They are know for sticking open or shut. A tap on them can free them..A look inside even by a novice may also reveal something burnt or unplugged etc.

Our 60sdx took an electrical hit, and now, when we turn it on it goes to protection mode. What do we do?


All of this involves some testing:

I would remove back cover and look at the several green LED's on the board and the red one as well.

The red one should be lit and the green ones should light when set is turned on; primitive self check as each green one is tied to a voltage in the set's internal power supply.

Usually when an electrical hit parts at the in to the power supply get taken out.

Got a red led lit on the board?

This like all sets has standby power supply built into it: some sources are active 7/24 even if set is off and they usually take the hit.

Not knowing if you have a voltmeter and or know how to check I would suggest look at the led lights on the board.

Before you rate this information LET ME KNOW WHAT YOU FIND.

Good day, seanhanna;

Hitachi has LED’s, green ‘lights’ and a red light to determine what circuit may be the problem; after removing the back of TV, bottom only, plug TV back in and observe which LED’s come on …..BUT most important which LED’s don’t come on; locate and note number, EG; DP37 and etc.

Good luck, big IRISH. Ps let me know.

Power light stays on even when i turn off the tv.


If your talking about the little red LED on the front of the set don`t concern yourself over it, you have a diode that is a little "leaky" which just means it`s partially on when it`s supposed to be off. The diode is a pain to get at to replace it and it will NOT hurt your set to just leave it like this.

You can download a PDF from here: http://www.servicemanuals.net/results.aspx?type=SM&brand=0&model=50EX20B Make sure that the coolant is not leaking out onto the printed circuit boards. i have had the remote sensor cause this problem before and also I have had bad capacitors in the sweep and the main power supplies.
