Here is the link for the manual if you need it http://merchant.satisfusion.com/library/manuals/owners/50_60V500.pdf check page 57 - see if there is a timer lock activated somehow or a ratings lock check that the button on the remote is not malfuntioning by taking the batteries out and see if the problem persists check page 63 about screensavers !!!check page 67 about the on-off timer check page 75 - power issue troubleshooting check that there is not a problem with the bulb or the cooling fan - maybe an overheat safety device switching your screen off and then back on again. Hope this helps :)

SOURCE: Hitachi 50v500 blueing problem

I am not expert but before you go to a lot of trouble, read all of the post on the infamous "red cloud", "red blob" and "blue streaking". In evey case, it appeared that the light engine was the problem. We just had our light engine replaced and the TV looks perfect. We dealt only with Hitachis Customer Relations Department 800-654-7013. You will have to have a certified tech come out and diagnos the problem. Hitachi will then call and verify, with the dealer, that the problem is a defective light engine and will send out a brand new one.

We were told the part cost around $1500 (Hitachi covers that) however, they will ask you to pay for the install. Our install cost $400. Worth is to us as we paid $3600 for this set 3+ years ago and we have loved this TV. When you first call Hitchi, they will act like they've never heard of this problem but they will give you names of certified techs in your area. Once the tech confirms that it's the light engine, Hitachi will own up to the problem and send out the part.

You really should only deal with Customer Relations ( I listed their 800 number above as you will be chasing your tail so to speak with their regular customer service department. Good Luck!

If the light engine goes out call Hitachi and they will supply the part for free but you will have to pay for the service of installation around $300

I have one of these units, if the light is blinking and no picture as you have stated then you will need to replace the bulb in the unit. it is contained in the front of the unit behind the front panel on the right, you would remove the front panel after unplugging the unit, remove the single screw and pull out the box. replace it and then reverse the proces. the bulbs can be obtained for about $130.00 to $200.00 depending on where you get it from. Shop around.
