Question about Hitachi 43UWX10B 43" Rear Projection Television

1 Answer

Brightness I have a Hitachi 43UWX10B and noticed suddenly that the picture looks dark. The default setting is '50' so I increased it to '100' and the picture looks normal now. Am I looking at an expensive future fix or is there something I can try to alleviate the brightness issue?

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.

What's a Hitachi TV model 50v715 worth looks in good shape but dark screen and will thus be a major problem owner asking 100.00 for it


I would not pay 100 for it. maybe 20. If the screen is dark that would mean there is something going wrong with it. It will most likely cost more than 100 to repair. Unless you find parts on ebay and fix it yourself.

I have the same problem. I took the back cover off of the TV and blew all of the dust out and the TV started working again. But this only lasted 2 days. Now the TV is dark again.

Yes, you will need to replace the 2 convergence IC's. Hitachi part # CZ01341 generic part # STK394-160. These are the upgraded Hitachi parts for your set. Also, look for any burnt resistors near these IC's

try this

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.

Dark , blurry picture


MTNESTR, My guess would be the FBT loc.TH01(flyback transformer) Hitachi p/n#BW03004 which would be far less expensive than replacing the entire deflection board... A shop could ring test the FBT to confirm the failure. I do know the FBT in this unit has an internal resistor that is prone to failure. It is in-line with the focus block and if it's open it would explain the blur and lack of screen voltage to light the crts properly. The deflection board is about $290-$350 plus shipping and a FBT is somewhere between $60 - $90 depending on the supplier. Hope this helps! Bill
