Question about Hitachi 51UWX20B 51" Rear Projection Television

1 Answer

No Sound or Picture

I have a 5 year old Hitachi 51UWX20B when turned on there is no picture or sound. We've turned the TV on and pushed the menu button on the TV and remote, but no picture appears. We do know during the night before TV stopped working there was a power outage, but do not know if this effected the TV.

    I have similar problem. Power is on, nothing on screen and no sound remote and manual input attemps do nothing. All inputs transfered to another tv pluged into same power supply works just fine. It appears the projection system may have failed or maybe a fuse if there is one, but why no sound, unless the two are somehow conncted? Unusual to get two different problems simultaneously.

No picture, no sound, but TV will power up


Average life on all brands and models is 3 to 5 years. Average repair on this size and type of set varies but is usually from 150 to 250 parts and labor. I see very few sets of this type (any brand) that are more than 6 years old.

The bulk of sets in our shop (over a hundred sets on average) that have failed are under 2 years of age.

Hitachi 51UWX20B no sound, no picture, blinking green LED


The 392-150 is a higher current device then the 110---you can use either--this is normal in the hitachi sets---I usually replace both with 150's---check the led that does not light---should indicate which voltage source is bad---if it is one of the 2 voltages for the convergence ic's(one is a positive and the other a negative voltage) then the convergence Ic's may be bad---look for any discolored resistors around the ic's---one way to tell if it is a convergence ic is to de-solder both ic's and see if the set turns on(the convergence will be out the window) but if it comes on change both and do the alignments with the Hitachi remote. By the way----the led should have a location number printed on the top of the circuit board.

Double image/ out of focus with green and blue seperation


Your tv is crt-based and is out of convergence. In other words, the settings for keeping the Red, Green and Blue images aligned have drifted and must be reset. This is common with CRT projectors and CRT rear projection tvs.

Refer to your owners manual for instructions on re-aligning it.

No picture


Can you repeatedly get the picture to come back when you push on the back of the set? If so, yes, its sounds like a bad connection.

What happens when you use the tuner of the TV and with it connected to cable? Do you get a picture?

Hitachi 53 fdx 20b pojection tv


If you lost the picture and even the menu does not show up on screen, then I will bet that your high voltage has shut down or the computer has stopped the picture because it has detected a fault in the vertical circuit. In either case this is something that cannot be reset with the buttons or remote and should be handled by a qualified tech.
