Question about Hitachi 43UWX10B 43" Rear Projection Television

1 Answer

Black Screen, No Sound

About a week ago I noticed that the picture would go to brown tones and then fade to no picture, after the TV had been on for about 30 minutes. Then, all failed - i.e., I still have power, but have no picture and no sound. Help!

Re: Black Screen, No Sound

There are numerous problems that can make this TV set to be dead. The most common is the coolant fluid between the picture tubes and the lens leaks out onto the boards below the picture tubes. You can verify this by looking at the boards. you will see a small puddle of oiley liquid or an indication of moisture damage. If that is not the case. You can get the service manual and look up the trouble shooting flow chart that Hitachi puts into their service manuals. I happen to have a copy I could share with you if you wish. You will of course need to know what to look for and understand how these solid state circuits work inside of this TV set. If you do not understand about this TV set's circuits, play it safe and call in a pro to assist you with this repair, as this is not a place to be experimenting around inside of. Good Luck

No Raster, but sound works

sounds like vertical deflection has caused the tubes to go into blanking. Do you still have on screen displays? Try resoldering the vertical output IC. If that doesnt help the vertical output may be defective.

46" Rear Projection Hitachi - Green / Yellowish Screen

daveT29 - I had my brightness cranked, too. The picture went dark and off-color after moving the TV from one corner of the living room to another.

After waiting for the TV repairman for about 4 weeks, I "fixed" it myself. Take the front panel off (4 screws, then a black panel) and blow out all the dust. I was afraid to use a swiffer duster because of the static electricity, so i just used with my mouth blowing powers.

That's it. Seriously.

I have the exact same problem with my tv. Unfortunately, I'm not sure what is wrong or how to fix it either. I notice your post is from July. Have you found a solution since then? - Sarah
