Hitachi HD tv when put on stand by it start flasing red light after that it not respond to any remote or tv button or key how to solve this problem/

Did you figure out why the ac wasn't responding to the remote? I am having the same problem. I just cleaned out the filters but it's still not responding to the remote. I have already tried reset button in the remote, which didn't help. I am pretty sure that the remote is not out of battery.

you have a faulty parts inside..try to disconnect one by one the supply of all board until you get stable lights..

the red light turns on automatically after 120 hrs of running to remind us for cleaning the filters. once you cleaned the filters and inserted back , then just keep ac in stand by mode, open the remote panel and press the button on extreme right bottom of the remote ( see carefully in the remote, there is very light image of the filter is made along with the button). red light will go off. no need to press the reset button.... enjoy

First do you see a light indicating that the TV has power? There are two power buttons on the TV (the main power and the regular power button). The red standby light will light up when the main power switch is on. This indicator is just to the left of the remote I/R sensor. You can find the main switch on the bottom front of the tv (it is under the tv forward of the stand). Turn on the Main power if it is not on. Then try the power button on the control panel of the TV again.

Does the standby light change color or blink? (Red is standby, orange is power savings (no signal), blue is on.) If the main switch is on and the standby light doesn't come on, the TV has a problem at the power supply. Try unplugging the unit for a bit (at least 30 seconds) and then plugging it back in. This will reset the internal circuitry. If you see a blinking light, then the TV is reporting a self-test failure. I do not know the codes for this model Hitachi Plasma TV.

The manual for the Hitachi P50H401 TV is available from Retrevo: http://www.retrevo.com/support/Hitachi-P50H401-TVs-manual/id/1233ci869/t/2/ . You will need to enter a code to access the pdf.

I'm assuming you don't have one of the special versions that were intended for large audiences that were only controlled by remote (no control keys on the front of the TV). Remotes.com has the original remote or a substitute remote if you need it. See http://www.remotes.com/remotes/servlet/rs?a=gmi&uuid=13104063628240&smodel=P50H401&brand_pn=HITACHI_P50H401 .

I hope this helps.

Here are the 9 codes that could match your universal remote to your Hitachi televisions;

10145, 11145, 10151, 11960, 10679, 10165, 10386, 11993, 10842

if these codes do not work you can search for your code by following your instruction manual.

here are the instructions to do a code search if for some reason they are missing from your manual.

Searching For Your Code
If your home entertainment device does not respond to the remote control after trying all of the codes listed for your brand, or if your brand is not listed at all, try searching for your code.
For example, after trying all of the codes for your TV, you still cannot get the remote control to operate your TV, then:
1. Turn on your TV.
2. On the remote control, press TV once. Then press and hold Setup until the TV key blinks twice, then release Setup.
3. Enter 9 - 9 - 1. The TV key will blink twice.
4. Press and release the digit 1. The TV key will blink twice.
Note: Substitute 1 with 0 if searching for a Cable code, 2 if searching for a DVD, VCR or PVR and 3 if searching for an Audio device
5. Press Power and aim the remote control at the TV and press CH + one or more times until the TV turns off.
NOTE: In the search mode, the remote control will send IR codes from its library to the selected device, starting with the most popular code first.
6. Press Setup once to lock in the code.The TV key will blink twice.

Press the red and select together the red light flases twice enter the code for your television. instructions for this can be found by giong onto skt typein remote controls , this then gives a list of suggestions

or you can use the general method:

need model and chassis number and I' may help you email me

Replace the Z Sustainer Board, Part # 6871QZH044B and replace the Y Sustainter Board, Part # 6871QYH039B at the same time. If you replace one and not the other the bad one will end up shorting the good one and you’ll lose your picture within a week. You can do this work yourself by unplugging the unit and placing it face down on carpet (put down a soft blanket to protect the screen) and unscrewing the back of the unit (a power screw driver works great for this job because there are a few screws involved). The cheapest place to buy these two parts are: www.discount-merchant.com , or www.avextra.net, or www.ebay.com

TV - Made Nov. 1993, and the picture is so razor sharp clear that when my Cable company come by , one and all always say, "is the HD because the picture is so execeptional one it. When I say "no", the argue and say that they have NEVER seen a TV. that is no HD with such a perfectly clear picture. I get complements on it all the time. I picked it up in a pawn shop in 1995 for $200.00 .

The TV. Model is a CT 2043B HITACHI MAKE.
