Hi, i have a hitachi 50" colour tv 50HYT62U, purchased about 2 years ago. Has started switching on and off in a loop when I plug it in. Remote control won't work.

Your LED backlights are bad, but Hitcahi parts can be hard to get sometimes

2610,2663,2681. If you wish to get more; check the sites linked here. It has set-up code list & set-up procedure to many popular brand remote controls. One among it has general set-up codes to check with TVs and other devices are given, in the order of the 'device's brand name list' in alphabetical order. Pull up older posts. Search the sites by type in the brand name to your device in its search box at the top right part of the display window. It will help you to find the document easily.

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.

I'm having the same problem with the same TV and am on the exact same timeline. Anyone know how to set up a class action?

there is no tube in a projection tv it will be the conversion chips if picture colours aer distorted

1. Switch on the television
2. Hold down the mute key and red light starts blinking
3. Continue holding down the mute key while pointing the remote on the television
4. Once red light stops blinking try switching television off by pressing the red turn off key

Tested and method worked on Ferguson tv

If you provide model number I can suggest correct remote control to buy.

Replace batteries of your LG remote.
