Question about Hitachi 43GX01B 43" Rear Projection Television

Blue screen I recently replaced the convergence ICs on my set. all was well until recently. After dusting the Red, Green, and Blue lenses and the rear mirror with an eyeglass cleaner (basically a barely moistened towelette), i turn on the tv the next day and there is a blue haze over everything when i use component cables. I have switced to composite cables to see if my component cables were the problem. With the composite cables, the blue haze is gone, but the blue barely registers. I have tried adjusting the color both from the OSD menu and from the individual knobs inside the set, both with no results. I'm not afraid of electronics, but i am not a TV repair person either. Is this something i can fix, or do i need to take it to a pro? Thanks.

I'm pretty sure my component cables are bad. i plugged them in and now i get a red haze. That mystery is solved but i still have a problem.

I connected my s-video cable, and i get the same problem i was getting with the composites. The blue is weak. the picture quality is good, but it is dominated by reds and greens. i have adjusted the blue knob inside the set and that puts a blue flush on everything.

Also, i forgot to mention this in my original post, but my rear projection mirror was broken when i got the set, but was fixed prior to this problem starting. (fixing the mirror was why the TV was open in the first place, and then i cleaned everything.)

I recently discovered by service menu. How do i go in there and adjust the colors so that the blue is stronger? Is there a table of recommended service menu settings somewhere that i can use?

I would look for something real simple here. The problem appears to be in your component cables (I would suspect one being bad or connected to a wrong jack). If they are connected properly, try moving them a bit to see if the blue haze comes and goes or try different cables.

My 52in hd tv wont show a picture and when you cut it on it just light up red but no picture and i cant get to adjust the convergence on the menu.

If the screen is a bright red its indicating an issue with the CRTs could be the red has shorted or the coolant in the blue and green is needing replacement which makes the red Dominate. Looking into the blue and green lenses will verify if its a coolant isssue or not. The convergence issue is most likley failed convergence ICs and the associated 6.8 ohm resistors need replacment.

Have You replaced the convergence ICs Yet? They are Big Black ICs and will have part number on them .

Unable to align cross hairs on the blue lense. Dose the lense need to be replaced?

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.
This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
•Screen looks 3D
•Colors don't line up
•One or more colors can't be adjusted when using the convergence menu.
•Screen is bowed or warped.
•TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.

Red, green and blue colors don't match up on screen.

Please replace convergence out ICs (usually two) in TV.
If it is Hitachi 43UWX10B then its convergence out ICs are available in Part Store
Thanks.

The Screen looks 3D & Colors don't line up on my big screen????

If the convergence is off more than 1/2 inch or so you can't adjust. you have a failure of hardware. most likely the output IC. This set has 2 outputs for convergence. Each output contains 3 circuits, Six circuits altogether 2 red ,2 blue and 2 green. The normal customer adjustment will only alow adjustment of blue and red. They should be converged onto the green. There is a much more complex adjustment in the service mode for Geometry and convergence. These adjustments are only needed when you replace a failed componnent like the output ic. These ICs have been upgraded several times since the production of this set. The latest and most powerfull version is STK394-160. If feel up to it I suggest changing both outputs and the corresponding output resistors. Then do a complete geometry and convergence alignment.

Convergence ICs

the green is half controlled by half of each of the convergence Ics meaning green horizontal is controled along with the red and green vertcal is controlled along with the blue Ics. So if you have replaced both Convergencs ICs the problem is most likely a resistor that is in the green circuit. You will need a schematic to locate which resistors are in the green vertical and horizontal convergence circuit

Unable to converge red/blue

youre convergence ICs need to be replaced. You will need two STK392-120 ICs . You can get new ones here with online free support to help you do the repair, plus they send step by step instructions with pics on how to do the repair. Here is the link.
