I'll tell you what I tran into and how it got resolved...
I experienced the same problem , with the blinking light...
Purchased a replacement lamp..
It didn't work(After market Universal supposably)..
Well..Come to find out.The Replacement lamp's housing looks similar, but the connecters that come out the back of the housing weren't quite long enough to trigger the microbe that activates the lamp in the Television.
Luckily I had the original lamp and it's housing that came with the television..
Took the bulb out of the new replacement lamp
Placed it in the original housing , and BINGO..It worked and is still working...

    I had the exact same problem - replaced the lamp housing with the new but when I turned the TV on again, the solid lamp light became a blinking light. I thought the replacement lamp housing connectors were a little short so I, too, took apart the housings, exchanged bulbs, put the old housing back into the TV with the new bulb and the TV works FINE! Thanks for your comment - I never would have thought to just exchange the bulbs, because the housing looked identical!!!! Happy Holidays! 12-11-10.

I found a solution to some of these problems. I too have a Hitachi 50V715 which started to become dim. I changed out the lamp(using the same enclosure ), installed it and the cover, only to find out the TV clicked once and clicked twice only to turn off leaving "lamp" light flashing. Getting frustrated I installed the old lamp only to find out it still would not turn on. I then knew it was an installation problem. Looking inside the housing of the TV ,in the upper right hand corner there is a small metal tap I noticed that pushes a blue"dip" switch. The metal tab was bent. I straightened out the tab .Also I took a small piece of scotch tape and used it to hold up the tab in an upright position. If you look at the back of your lamp enclosure you'll notice a plastic tab portruding in the upper right corner. This must push the metal tab which engages the blue switch behind it. Installed the enclosure and it "worked like a charm" ! I major problem was the tab was curved and just needed staightening. Hope this helps somebody else.

Ours was still under warranty when that happened and we had a tech come out who installed a larger fan from the original. We haven't had the problem since.

Hitachi 50v500a: Lamp blew, oredered a replacement. Just installed it, and I still get the "lamp" light on and it wont power up.


Remove lamp and look to see the socket the lamp plugs into did not get bent out of position---just check to see if it went in right and after that you put the door back(set will of course not operate if door or cover removed).

If we assume New lamp good and installed correctly the next possible issue is the Ballast which powers the lamp--Not easy on this set to check voltages---should have a plug with over 200-300 volts from power supply going to--the two wire plug from the lamp goes directly to it.

My Hitachi 50V500A has a large area where the color is turning out to red. Is this a lamp or a complete light engine replacement job?


not the lamp. hitachi knowingly had a defect with the fan not allowing enough air to cool the lamp which has burned the red color lense resulting in the red on your screen. enjoy your new brick thanks to hitachi!

Replaced projection lamp and also cleaned out most of the dust inside the tv. will power on but shuts off before picture comes on tgen three red light blinks. please help asap. thank you.


Three red light blinks shows that lamp cover is not properly closed after lamp replacement. Make sure that the lamp cover is in its proper position. Try to reset the lamp cover and turn it on clockwise direction until you heard a click sound of a micro switch activated by the lamp cover, then put the set on..

TV will not turn on. Lights Blink and hear noise


Have you replaced the lamp ? Make sure the door cover is closed good because there is a switch that is made when the door cover is put back on. Also you could have a bad ballast board or bad power unit board. Just a thought...... Hope this is helpful.
