Question about Hitachi 53UDX10B 53" Rear Projection Television

Open Question

Where is the "little blue button" on Hitachi rear projection TV?

I have an Hitachi 53UDX10 rear projection TV that is stuck in the screen that consists of 9 cross hairs (I got there after a ROM save error trying to adjust color convergence misalignment from the service menu). The 52" screen of this TV sits on a "pedestal" that houses the speakers. I read some other threads here that for some Hitachi models I should remove the front panel to access a "little blue" reset button that gets me out of the cross-hairs mode and back to the service menu, but there are no screws in the base of the front of this TV that would let me remove it. Does anyone know where that reset button would be on this model? Is it behind one of the back panels?

    To answer my own question, the "little blue" reset button on the
    53UDX10 is on the convergence board which theoretically should be
    accessable from the front left side behind the speaker panel, as it is
    on other Hitachi sets. I reached it from the rear of the set while I
    had the back cover off and the set unplugged. But I still don't know
    how to get the front panel speaker cover off to access this reset
    button while the set is on. There are no screws visible. Is this panel
    clipped on? I've tried tugging at it without success. Any help would be
    appreciated because I'm still stuck in the service screen with the 9
    cross hairs.

    More answer(s) to my question: The entire front panel (including the
    L&R speaker covers) of the 53UDX10B is held on by plastic clips. I
    tugged on the upper left hand corner of the speaker cover with my
    fingertips, and it came loose. Then I pried off the rest of it with my
    fingers. That revealed a plywood panel that served as a front cover for
    the circuit board area and that was held by 5 screws. I removed those,
    and that plywood panel came off, giving access to the insides of the TV
    from the front. Hope this helps someone down the line. BTW, the "little
    blue button" is on the front side of the convergence board which sits
    to the far left as viewed from the front of this TV set.

If you mean that one of the colors has suddenly drooped toward the center, creating a curve along the side where the colors no longer line up, it means that one of your convergence IC's has burned out and needs to be replaced. You should not play with the convergence settings when this happens because when the IC is replaced, the settings will be all out and have to be reset. It is a good idea to replace both STK392-110 IC's with the newer improved STK392-150's. If you have never replaced convergence IC's or realigned convergence circuits then allow a qualified tech to handle it for you.

it sounds like your blue convergence ic is getting weak you need to replace the ic's STK392-110 and you should replace both because when 1 is bad the other will go real soon. They are inexspensive at the sight I posted and you will also get free tech online support if you purchase them there.

How do you access the convergence calibration menu on a RCA P52926 Rear Projection TV


Hello
To access the convergence calibration:

Press the MENU button on the remote.

2. Press 3 to select the Screen option.

3. Press 4 to select the Adjust Projection TV option.

4. Press 4 to select the Advanced Convergence option (the
Advanced Convergence screen appears).

The green pattern is fixed. The red and blue patterns are adjusted to

the green pattern. The Red Convergence appears first by default.

5. Colored cross-hairs show the current adjustment position on the

grid. To move the cross-hairs to a different position, use the

CH+/- buttons on the remote to move the cross-hair highlight up

and down, and the VOL+/- buttons to move it right and left.

6. Use the arrow buttons to adjust the red pattern. Each press of

the arrow button makes a slight adjustment from the center of

the cross-hairs - you can press and hold the desired arrow

button to make a faster adjustment, and then make fine

adjustments with single presses of the arrow button.

7. Press the INFO button to switch to Blue convergence and follow

the steps above to adjust the blue pattern.

8. Press OK to exit. You will be asked if you want to save the
adjustments

Yes Saves adjustments.

No Returns to the Advanced Convergence screen allowing

further adjustments.
Clear Exits screen without making any changes

Note: Before you use the advanced convergence feature, you must
complete the previous steps to align the tubes

How do I adjust the convergence properties on an RCA rear projection tv?


Normally on the RCA rear projection TV's you would bring up your menu and choose the Setup menu, then press OK on the remote. That menu would then have Convergence as a choice. Once that was chosen the next menu would give you the choice of either letting the TV run it's own Autoconvergence program, or you would select either Red or Blue convergence.

Choosing Red Convergence would bring up a Yellow cross-hair in the middle of the screen. If the Convergence was not correct you would see separate Green and Red cross-hairs. Once they were perfectly aligned you would again see one Yellow cross-hair.

Choosing Blue Convergence would bring up a Blue cross-hair in the center of the screen. If the alignment was out you would see 2 Blue cross-hairs. Using the Up and Down and Left and Right cursor keys you would adjust the alignment until a single solid Blue cross-hair was in the center of the screen.

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.

Does it take some type of gel under the lights, the colors are a little blurry


i also have this tv. i removed backcleaned mirrior, back of screen and lenses VERY GOOD. Then turned on tv go to convergence, sepaerate cross hairs then adjust focus on lenses. Then lenses rotate maybe about a 1/3 turn total by hand. Grab ring that houses lenses and turn until cross hairs are as clear as possible. This can be done with out help by watching inside of screen. red and green are adjustable, the blue is adjustablealso but i couldnt find blue cross hairs, maybe by covering red and green lenses the blue will show on screen. anyway when done and cross hairs are clear,lenses, mirror and screen are clean, you can adjust covergence and get a very clear screencleaning will also brighten pic.

Toshiba tp50h60 convergence


Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs. To get fixed either call in a local TV repair company or goto sites such as Tv Repair Kits to get a repair kit with instructions. Here is there link.

They have put together complete kits for most models that include the parts, step by step photo instructions, repair assistance, etc.

My hitachi 53udx10b tv is out of focus.


rojamon,

That #4 error is listed as "overflow," and I got a"ROM overflow" errorwhen I tried to save my adjusted convergence data.I don't know whatthat all means yet, but if I figure out my problem,I'll post backhere. I've read here and elsewhere that the out-of-focusproblem comesfrom bad resistors or amps on the convergence board. Youcan tryservice mode to adjust convergence. Press the Magic Focusbutton, andthen press it again to stop it, and then press the Statusbutton onyour remote. Here's a link to the manual convergence procedure (scroll down).
