The most common thing onthese Hitachi's is dusty or dirty CRT's sockets. All it takes is just for one to be dirty and it will effect the other 2 CRT's. The simple easy fix is to remove the speaker grille, then remove the access panel wich will expose the CRT boards. The CRT boards have to have a screw loose to get them to come off. Be careful as they are fragile boards and also make sure the screwdriver is not magetic and that the set is off. Just take a can of compressed air and blow out the sockets and the pins on the CRT's (again be careful as the pins are VERY fragile and will bend easy). Once this is done put the sockets back in place and you should have a normal bright picture again. If not you do have other issues but, I have fixed I would say 96% Hitachis with dark pictures this way.

We have a Hitachi 57XWX20B Rear Projection TV. We moved this week and now the TV picture is very dark. We have tried the magic focus and adjusted the brightness, yet the picture is still very dark. Any...


one of two things on this model==clean the lens on top of the chassis--the round large black ones.

Second: there is a resistor in the power supply that changes value and will cause this----also with set unplugged and back off since set was moved carefully look for any plugs not fully seated etc.

This is called image burn, or image retention. There is no cure for this. The image has been burned into your picture tubes from having the same image tuned in for too long.

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 picture


use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.

Brightness


If you want to attempt the repair the fix for most Hitachis going dark is to remove the front panel and get access to the 3 CRT's (picture tubes) Then one by one with the set off and unplugged, remove the CRT boards from the CRT's and blow out the sockets with compressed air. Once all three are done cover it all back up and reapply power and 99% of the time your picture will return to normal.
