Question about Hitachi 43UWX10B 43" Rear Projection Television

1 Answer

Flashing Power Light

I've noticed that others have described symtoms similar to this, but I haven't really noticed that anyone knew what the problem was. Maybe I just didn't search thoroughly enough. In any case...yesterday when I tried to turn the set on the red power light flashed on and off at about 1 second intervals. After a couple of minutes it flashed off and stayed off. Screen stays blank. Happens if I power up with the reomte, or the power button on the front of the set. Problem is repeatable. Any ideas? Thanks!

Re: Flashing Power Light

This set is going into shutdown. It has a safety feature that will not allow the set to turn on until it checks certain circuits. Inside the set there are multiple Red LEDs and one green one, that light up at turn on. One of them is not turning on and thats the circuit that needs repaired. The most common I've found is the Horizontal Output circuit. Usually the fusible link on the secondary in the power supply. Sometimes it goes as far as the High Voltage Transformer. Of course this is just one of the possible four circuits that cause this symptom. Hope this helps.

Hi James,

First of all thank you for posting your question here at Fixya.

Flashing of the LED light green has two error code.

1. Lamp Fan failure - if the lamp LED at the front panel blinks green, this is an indication that there's a malfunction on the lamp fan. You've mentioned that you've replaced the lamp, please make sure that the connector of the fan and other connectors are securely connected. Double check it.

2. DM boot failure - If the Timer/Power at the front panel blinks green for more than 1 minute, this is an indication that the DM failed to booted up. I have a link where you can buy DM repair kit, click it HERE, it includes parts that are know to be faulty, illustrated instruction that will guide you in the whole process of repair. Your unit is a V26 chassis, when you are on the link, you can see two version of the DM repair kit for V26 chassis, one is the same working voltage of the capacitors and the other one is the upgraded version. It's up to you if you are going for upgrade or not.

Please let me know if you need further assistance.

Have a great holiday!

Kind Regards,

I have a RCA D52W20 52" HDTV Ready TV which I

Unplug High voltage lead from HV splitter. This is a red wire going from HV transformer to similar (white plastic) device located up front, between picture tubes. Disconnect the one which is coming in, by strong energetic pull down with pliers. Leave those which go to picture tubs in. Make sure that disconnected wire is far from other components or metal parts (high voltage - SEVERAL INCHES SPARK CAN OCCUR) Turn the unit on - if different than 3 blinks - the splitter is your problem.

Tv won't turn on and timer light is flashing

Look closely at the flashing light... Does it flash in a sequential pattern like 4 blinks, a short pause then 3 blinks, a short pause and then 1 blink or some similar pattern????

If so, then the light is not a timer light, it is a trouble indicator light and signals that a component inside the TV has failed testing when the unit tried to power on.

If not, then I have no clue about what you're describing as a timer light. I am unaware of the Misubishi having a timing light installed.

Flashing light and no power

Yes they could definately cause a shutdown, thats a classic symptom for many rear projection TV models if the ICs simply fail the set will work but the alignment is out of control, and if the ICs short the set will shutdown into protective mode. On your model the ICs are mounted on the sub board so its better to just desolder the two ICs completely then try powering up the set with all wire connectors plugged in. If the set powers up with distorted convergence you will know the ICs are Bad. If it doesnt power up then the problem is elsewhere and you may need to replace the sub board.

Immediately Shuts off with blinking light codes

I suggest doing a google search using the tv model # and brand.
I have learned myself that different big screen tvs seem to each have their own common problems. I have read before of power supply issues that cause what your describing.
