Question about Projection Televisions

TV shuts off

I have a Hitachi 55vf820 which I purchased 2 years ago. It was a good purchase until recently the television started to turn itself off automatically about every 15 to 25 minutes with no ryhme or reason. The lights on the front of the set for the power(blue), Temp Indicator(red) and Lamp indicator(red) in that order start blinking. The set then powers off for about 20 - 30 seconds and then turns itself back on again.

Please help...

Re: TV shuts off

I would suggest that you guys turn the unit off when this happens, unplug the unit for 30 seconds, plug it back in, and see if this helps. If this does not solve your problem, you should call 1-800-448-2244, so a service center in your local area can be found for further assistance.

well..the control board has this sort of issue. sometimes, if you turn if off long enough to reset itself, this may clear..otherwise, it's a replacement of a non inexpensive component..

what's your technical ability like?

Hitachi Lamp Light Came on

Good Day, CCooke;
Lamp Number for the 55V825 Model is; UX21516.
To replace LAMP remove Front Panel outwards until the quick snap disengages. There is small cover on the left hand side, using a philips screw driver; remove. Two more screws secure lamp, use handle to remove. ALWAYS, unplug TV from A/C power source first. Good Luck, big IRISH.

Problem with tv

Pretty typical for lamp life. Buy a new bulb (not the whole lamp assy) from us ( or one of the many bulb sources on the net, install it yourself and save a lot.

Hitachi 51f500

I would try throwing it in the trash and purchasing a new television. Just a hunch, but I think that would solve your problems. Good luck!

Hitachi Projection TV Model 46EX1B

 The most common problems I have found in this model is solder joints going out in the vertical and on the driver transformer.

 I would say the picture tubes are probably starting to go out by now and the technology is changing.

 Look at the new sets. LCD and DLP are using LEDs. 

 Manufactures are beginning to equip their sets with ATSC tuners that bring in High Def. stations by using a pair of rabbit ears.

 In a little over a year most signals must be High Definition and the government is supposed to send out checks for about 40.00 to help fray the costs of converter boxes to convert the older set.

 So, my thoughts are, the set is about 17 years old. The cost of repari and the repair itself would be like putting a bandaid on it.

 Capacitors by now are beginning to dry out and solder joints are starting to open up, not to mention that the picture tubes are getting weak and changing luminance and fading..

 Most sets I repair at this age have future repairs.

  Check out the new technology.
