Question about Hitachi P42H401 42 in. Plasma HDTV

1 Answer

My hitachi plasma screen turns off after a few seconds and has a blinking red standby light.

The red standby light continues to blink and does not stop. Also, the TV doesn't stay on long enough for me to go into settings or anything, only 2-3 seconds. Any help could be appreciated. I'm wondering if I could fix this with the help of my friend, who knows some things about computer parts and their installation. Also, how much might it cost me if I just took it into a TV repair place?

    If it is the power control board as someone suggested, what part do I need to purchase and replace?

    You can try to get your hands on a service manual or check out this web site:

    You might give them a call and run the symptoms by them and see if this is the board to fix your problem. Good luck and be careful!

I suspect that your power controller board has a problem and is causing the shutdown. If it is under warranty, get it fixed under warranty. If it is not, it may be possible to purchase the board and install it your self. Be careful though plasma TVs have some areas to avoid when servicing.

    Hello Robert,

    Thank you for the response, I hope you are right - I may try to repair this with the help of a friend. What would the power control board be called, a PCB? I'm looking online, so that I can purchase one, but cannot find it.

Jake I have a 52 inch Panasonic plasma tv that will only run the fans for a few seconds and shutdown red light blinks 10 times and repeats.


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Hitachi 50 in flat screen tv plasma blinking blue light


How many times this standby/power light blinks at one time switch ON? Count it carefully. These blinks are fault indication, and known as blinking codes. From the number of blinks occur at one time switch ON; you can get an idea about the faulty circuit stage inside the TV. This will make repair easy. For more information, check the link http://electronicshelponline.blogspot.com/. If the blinks continues, and non-stop, the fault should be with its main system control IC, and with the memory IC.

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...
