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.

My TV is the Hitachi model 51UWX20B and tried using magic focus to line up red color. Picture looks like 3D with red off center. When using magic focus it gets to the red phase and it shows the number 5...


You need to replace the STK ICs which are Convergence ICs STK392-110 use 120s or 150s
also check the small ohm resistors around ICs . They are Big Black ICs and will have part number on them ,should be located on the Right hand side of Chassis .

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.

Hitachi 55FX20B 55 in. Rear Projection - no picture or sound


TV always has high voltage shock risk while repair. As you said you are not familiar with TV repair so better to handle repair person this issue.

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.

Sound but no picture


loss of picture with sound ..loss of picture could one of many problems.. these units have serval specal fuses that a tech would need to check. loss of high voltage is a possibility. i would think this would be worth getting a tech to check out, the fact you still have sound may be a positive,

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.
