Hitachi 62vs69A no picture no sound steady blue power light only

Checked the 3 fuses, bulb, connections, everything that I could get to by removing rear panels and pulling the board out as far as possible. Four months out of warranty.

    I just replaced the lamp and no change. The blue power light comes on if you hold the power button in. I does not flash and still no picture. The remote does not turn the power on or off either, new batteries in it too. I can hear the relay click on and off each time it is plugged in or unplugged but a single click only, does not click continuously.

    I read some where too that it could be a ballast. Does it sound that that could be a possibility?

    Thanks Fixyy and kevin0000. Looks like it may be this power board (for lack of a better name) and that I'll need to trouble shoot it at the component level. I'll down load a service manual and get back with you. Now the hard part, getting my big hands in there to unplug all of thos small connectors so that I can do the bench work.

    fixyy - It's been unplugged since the 14th untill tonight (18th) when I tried the new bulb.

    I'm still working on this as time and Hollidays allow. I did find the Service Manual online and downloaded it. I've got the Power Board out and just started to trobleshoot and have found nothing yet.

    As mentioned in another suggestion that someone would have to come in and read the codes and reset them. This would have to be by some kind of scan tool or device that could be plugged in some where because there is nothing that appears on the screen. Outside of forcing the blue light to come on by holding it in and hearing a relay click when it's plugged/unplugged, it's dead.

Unplug the device for some time then reconnect it and check out. if this does not solves your problem then on the main board check out for any loose capacitor or any faulty burned or leaked capacitor,that has to be replaced as because of that faulty capacitor the circuit is not able to complete and showing this problem.just get it checked and replace it properly. u can get new capacitors and other spares at radishack websites. thanks.

    Ok you have the steady blue then it seem issue with the light engine. There's a good chance that it's not the worst, like a light engine failure... Bad news is you'll need a tech to do it. It need to have a memory initialization done from the I2C menu. There
    are a list of codes the tech will write down from the I2C menu then
    perform the MI.. Then he goes back in and resets the codes from his
    notes.. That's the boiled down version, but there is a lot to it - take
    my word..

    When calling around to shops to find someone qualified ask how much
    they charge for performing a memory initialization per Hitachi bulletin
    and see what their comeback is - - ...

    And let me know how this turns out for you.

    I have had people on this forum that wanted the instructions and tried doing it themselves, but one ended in disaster

Tv turns on for a few seconds then the picture and sound turns off and the blue power light just blinks

It will do the same thing, until a repairman comes out, and services the TV set...

Symptom: No power / Dead Unit / Comes On and protects itself, Power LED may blink in 3 or 4 times cycles.

Cause: Check/Confirm SDR buffer ICs are not shorted, follow link to check. If so, replace affected SDR PWB.

I have a 50vs810 dlp. The blue and red lights flash in sequence when I turn it on.When they stop flashing the red light for the lamp is on. The yv has no volume and no picture. Is it just the bulb or does...

More than likely, it is the bulb. My hitachi 50v715 would come on(light up and show picture) 3 to 30 sec's with out the lamp indictor even lighting up. Put a new bulb in and works great. So I would try a new bulb. Look in your manual for the bulb number. Buy an original hitachi bulb they last a little longer.
