Question about Hitachi 50V715 50" Rear Projection HDTV-Ready Television

1 Answer

Lamp, power and temp light all blinking

I believe this means the fan has quit working. I am wondering if it is time to buy a new TV rather than put money in to this TV fixing the fan. What do you think?

Depends if you replace the lamp and clean the fans for bulb and pull apart projector on your own you could make it pretty cost effective. If you have someone else do it probably not worth the cost.

Check your color wheel. There is a DIY guide for replacing the color wheel. Mine did the same thing yours is and my color wheel was all busted up. Unfortunately after replacing the color wheel my set continues to do the same thing, but this could mean I need to replace the ballast as well.

Hitachi 50VF820 (LCD projection)randomly turns off, all three lights (temp,lamp,power)blink then the set turns back on after approx. 30-45 seconds. Lamp was changed approx. 4-5 months ago. Cleaned out all...


I believe I may have solved this problem by putting a small fan blowing on the intake of the Lamp fan. I put the fan in place and the TV has not turned off randomly since. That was only a day ago so I'll see if it is a permanent fix. If so I will probably try to mount the fan on the back of the TV out of sight.

TV will not power on 4 red blinks


I found the following suggestion on avsforum.com and it worked perfectly (going through the lamp door).

I'm a longtime lurker not much of a poster, but this happened to me to yesterday. I used civicsixxx's advice and this works. However you don't have to take anything apart. All I did was take out the lamp then put your hand in carefully to the right and you'l feel the fan just give it a spin and plug back in the light and the TV your good to go. Hope this helps.

Tv keeps turning off?


cutta, you will most often hear a click on boot then the fans start up and lamp will then fire. The picture will start to show up....at what point does it shut off? and do you hear a click when the tv is turning off? Is it the complete tv shutting down, fans and everything that turns off? Do you see any lights on the the front panel "POWER", "STATUS" or "LAMP", what are they doing? If you see a Power, Status or Lamp light after it shuts off the below are what they mean if there is an issue. POWER - STATUS - LAMP - CONDITION/ISSUE: Off - Yellow - Off - Temp. high/dirty filter/excess room temp Off - Off - Yellow - 4000 hrs. Lamp usage warning Off - Off - Blink Yellow - Lamp Cover open Off - Blink Yellow - Off - Air Filter Cover open Off - Off - Red - Lamp failure (failed to turn On or broken) Off - Blink Red - Off - Fan Has Stopped Off - Red - Off - Circuit failure (short) or DVI cable disconnected If you want to check for the last "Error Code", after you first turn the TV on, by pressing the front panel ?DEVICE? and ?MENU? buttons at the same time and holding them for 5 seconds, it activates the Error Code Mode. The ?Power LED Light? blinks/flashes (1/2 sec delay) and then flashes again denoting a two digit Error Code indicating no problem or an error has occured since the last Initalization. i.e. "Power light" blinks 3 times (1/2 second delay) and then blinks 4 times then 1 sec delay and repeats a few times. This would mean "Error 34 - Lamp abnormality". See below for error codes..... Error Code - Description or issue 12 - No Error detected, check Power Supply 32 - Lamp Cover is open 33 - Air Filter Cover is open 34 - Lamp abnormality 36 - Light Engine (DMD or LAMP Fan stopped) 37 - Exhaust or Lamp Ballast Fan stopped 38 - Lamp temperature high 39 - DMD temperature high 41 - Short is detected 44 - DVI cable between FMT & Engine disconnected. Sorry for the long answer but it was an open ended question.
