SOURCE: Hitachi 43UWX10B TV went off constant clicking

it could be an internal corruption problem, but I doubt it. This problem is usually a serious power failure and generally very expensive. Sorry to say.

ONE: First, reset the tv by unplugging the power cord and let it remain unplugged for at least 4 hours. When you plug it back in the internal codes will come up as factory default settings. It may reset the power control section, but I doubt it; maybe 10% chance.

TWO: Look for a fuse on the back side of the set. It would be a black round knob with a fuse inside when you unscrew the cap. The fuse is usually about 1.5 inches long and 1/4 inch in diameter with metal on both ends and glass tube in the middle. Replace it with the exact same rating. It will probably blow again when you put in the new fuse (90% probably) and you will have to find out what is causing the failure.

THREE: If nothing seems to make any improvements, you will need to have a trained tech come to your home for a house call. If you can find someone who has experience with your model or similar chassis from the same manufacturer you will be better off.

IS THE SET WORTH FIXING: Yes, generally speaking, big projection sets are built to last 10 to 20 years. If you like the set and it has been a good product for you it would be worth fixing. The cost of repair will likely be in excess of $200 plus the house call. But that may not be a bad investment to keep it running for another few years.

But, in the long run it is a decision you will have to make.

Technically speaking, the cause of power interrupt failures are caused by heavy power drawing circiuts such as the projection tubes, power supply and high voltage sections. The projection tubes are very, very expensive to replace, but the others are not so bad.

Hope this helps you get started on the right solution.

Thanks for sending in your question and let me know if you will need further commentary.

Have an hitachi 53uwx10ba red light on front is on but no tv

on some TVs, the lights do not turn off so that is not that big of a deal.  If you want to make sure, unplug the TV and then push and hold the power button for about 30 sec.  Then plug the TV back in and that should fix the light if it is stuck. (Pushing the power button wile unplugged will reset the system default!)

Hitachi 50UX26B V6J028894

Good day, joefrost;

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.

Hitachi 55VG825 rear proj television blinking light and screen doesn't light up

Refer to owners manual ! Blinking indicates the type of fault that is occuring on all your tv sets. example : power light on red - indicator light beside it green but blinks rapidly for half a second rapidly then shuts off. This refers to a faulty lamp or a lamp that is near its expiration. Read your manuals if indicators refer to easy repair sweet, but if it says call tech then bummer...
