SOURCE: Dark Picture

The procedure for correcting dark picture is EXTREMELY dangerous.. If you're not sure about what you're doing call a qualified technician or you could seriously hurt yourself or get killed!

Picture Dark, abnormal, Changing Color Temperature

  • Clean the Spark Gaps on each CRT PWB. Remove the Cap, clean the contacts with thin fine sand paper, blow out, reseal.
  • Remove the CRT Sockets, clean the pins on the CRT. Push the CRT socket on and off several times.
Make really sure before you sttart this process that the Tv has been unplugged for several hours and that you discharge the crt as you remove the anode. There is some extremely high voltage present for hours after the Tv has been off...
Or get a reputable shop to come out and do the procedure for you - - might just save picking yourself up of the opposite wall.

SOURCE: problems with brightness on the hitachi 50v810

Yes, they dim as they age, and you've done well to get 3 years out of one.
Projection TV makers charge an arm and a leg for their replacement lamps. They make it easy to do but as a result the custom lamp assy is expensive. The trick is to just buy the bulb for your model TV from any number of us aftermarket sources at a fraction of the lamp price and install it in the old lamp yourself. really easy.

SOURCE: Pictures very dark, Brightness all the way up. Contrast does not adjust

I have the same problem. I was able to temorarily fix the issue by taking the back cover off and blowing all of the dust out. But this only worked for two days. Now the problem is back. Did you fix the issue with your tv? Thanks.

Dark picture after changing bulb


If not bright again and not a generic bulb-possible problem with the lamp ballast that powers the lamp.

PICTURE NOT AS BRIGHT AS I WANT HAVE TRIED ALL . TV IS HD REAR PROJECTION . I HAVE TRIED ALL AJUSTMENTS,COLOR,TINT,FORMAT,SHARPNESS, BRIGHTNESS ETC. LAMP ONLY ONE YEAR OLD.


Unfortunately there are 2 IC's and a capacitor that can cause this set to be really dark. Without proper troubleshooting it is impossible to diagnose. Have a shop check it out for you. Thanks

Dark Color on TV. Can't adjust the color correctly


Having same problem now for a second time on a 57T500. First time was a bad green bulb that was covered under warranty. Only lasted 2 years....currently debating wether to fix or buy a new set. Bulbs cost about $300. Set is only 5 years old, so very dissapointed with quality.
