Question about Hitachi 43UWX10B 43" Rear Projection Television

1 Answer

I hit the accept key without resolution after paying for online assistance

Hello I am having problems with the white green and pink or red not lining up properly. I opened the back and found a resistor rk58 that measures .5214 Mega Ohms. The resistor is discolored so I can not tell the rating of it. I would also need to know the ratings of the other associated resistors. Any help would be great.

    I did the same thing I tried to line up the lines for color. Then hit the resolution button it lined up for a few minutes. Then it messed up again what needs to be done.

Hi

>>Does the chip STK392-120, looks burned.
if yes, replace it.That will fix the problem.

>>There are two IC's, a 392-150 will be the best replacement, and if there are any large burned resistors on that board (should be pretty obvious), then they need to be replaced, too. If there are , let me know the board designator number (it will be "RK-XXX")

Thanks

Riz

Double image from red bulb


Hello,

It's a convergence issue. Go into the main TV menu under video settings and look for convergence. If it has an auto convergence select that and wait a minute the TV will adjust itself and give you a clear picture.
If the TV does not have an auto convergence and just regular convergence than select this. It will give you a grid pattern on your TV and you have to move the cursor (using TV remote) and adjust each "point" so that each line is perfectly white. If you notice red or blue anywhere on that "line" then you have to adjust using the up, down, left and right arrow keys to "line up the red and blue lines with the nearest white line. It takes time and patience to do, but when completed, all lines on the grid pattern should be pure white and you will have a great looking picture.
You have to do this will all TV inputs (Video1, Video2 and so on) the reason Zoom looks good, is because you never used that screen as much and so the lenses didn't have a chance to get out of synchronizing.
RP TV's are made of the three lenses (red, Blue and Green) and as you watch TV, these lenses slowly get out of alignment. So you should do a convergence about twice a year to make sure nothing is out of whack.

You can pay somebody to do it, but may cost you like 100.00 or do it yourself, it is very easy just tedious and time consuming. If you have the auto convergence than your golden because this is the easiest way to "reset" the TV.

Hope this will help in solving the problem....

Since it is 4-5 years old it's a 50-50 chance that the TV has the auto feature. Good luck and if you still have the owners manual, I would read up on the convergence section in the manual.


Take in solving the problem.....

Good Afternoon, i have a Mitsu Projection TV 1080 HD series and cant seem to find a place to plug in the HDMI line..any suggestions?


You can use an HDMI-to-DVI cable for the TV's DVI input and this would give you video at full HD 1080p resolution but you need to route the audio via standard red & white RCA. It would be better if it has digital audio inputs such as optical or coaxial to get Dolby Digital and other digital formats from your source.

If in the unlikely scenario that it does not have a DVI input (which looks similar to your PC's blue VGA only wider and is white) you can hook it up to your component video-in (which is the red/blue/green RCA inputs). For this you need a cable that has HDMI on one end and red/blue/green for video RCA's +red/white RCA's audio.

This would give you 1080i resolution with stereo audio.

Hope that helps.

Pink and green with double writing


Are you able to do a multipoint convergence adjustment in the convergence menu? Do the red and blue adjustments move in all four directions/ Let me know and I will try to assist you.If the anser is no to either problem you will need new convergence ICs and convergence resistors.

Arched pink lines across screen. Now green and pink double stacked wording.


Projection sets have two very common problems.

The first common problem is convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

My rca d61130 projection tv has red/pink faint lines


It sounds as thought he convergance needs to be adjusted. You will need to push the auto adjust button or go into the menu and do a manuel adjust. Any adjusting instructions should be listed in your Operator Manuel. If you require more assistance in this matter, please write back. Good Luck
