This is a very nice tv very strong, but you have a problem on the convergence circuit or more likely on the power circuit for the convergence and this is the reason why the main processor it doesn't recognize this circuit. it need service not a mayor problem.

Picture not in focus


Devices: All projection TV's (HD or analog), especially Samsung

If its a Samsung HCN653W (or similar model), the first thing to try is the menu option named "Magic Focus", which tunes the set's focus.

Otherwise, it sounds like a job for a convergence. Perform a convergence procedure on your TV, and if the problem recurs within a few days/weeks, then your TV's 'convergence amplifier' board (aka "convergence amp board") is starting to fail.
This board may fail completely, in which case, your convergence procedure will fail to improve the picture.
A "convergence procedure" can be performed entirely by just using the appropriate setup menu option and your remote control.
This board may partially fail, in which case your convergence procedure will properly converge the Red, Blue, Green colors on just part of the screen, whereas a properly functioning convergence amp board will allow complete convergence of the colors across the entire screen.
Your TV's convergence procedure instructions will be found in your TV's Owners Manual.
At least one Projection TV manufacturer recommends that the consumer perform a convergence procedure every 30 days, but most TV owners find that excessive, and might only do one when (a) there's an evident color convergence problem in any part of the picture, or (b) once every 3-6 months.

How-to video: www.youtube.com/watch?v=esk4nYZKFcg
how-to instructions: www.ehow.com/how_2034880_perform-convergence--tv.html


cost to you: $zero
.

If the convergence amp board is bad, cost for a service call would be $300 (USD) plus $100 for a new board plus 50% markup on parts = about $450 (USD)
Cost to order a new board online: about $100 (USD) + shipping + sales tax.
Alternatively, if you can solder/desolder STK's (Power Amplifier Integrated Circuits), one can repair a convergence amp board for as little as $30 (USD) or so.

Mitsubishi rear projection picture that has a blue/green tint


Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as www.TvRepairKits.com

Common Problem #1) Convergence has gone out

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 yourconvergence 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. The power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

What you will need to do is convergence. You can get a repair kit fromTvRepairKits.com . It includes replacement parts,step by step instructions, support, etc.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from TvRepairKits.com . It includes replacement coolant,step by step instructions, support, etc.

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

Convergence


Have you tried to adjust the convergence in service mode yet?
If not here are the steps.
1) Turn the TV off with the System off (under flap of remote)
2) Press: Display, 5, Volume+, then Power. If successful, service text will appear on the screen.
3) Use 2 & 5 - to select the PJE category. Be careful, like your computer, you don't want to be adjusting the wrong screen.
4) Press 9 - to get to the convergence adjusting.
5) Press 6 several times to get the convergence screen of choice. (I like the grid)
6) Use the remotes arrow keys (joystick), move the brackets around until you have found the area to adjust. Press the center of the joystick to change the bracket from white to a color. Use the joystick to adjust the color(Push it sideways or up and down and hold). Press 3 to change color to adjust(red, green or blue). When done, press center of joystick again, this will turn it back to white.
Note: Try to keep the grid even and square.
7) Repeat step 6 for all parts of the screen that need it.
8) Once done, you need to save your settings. Press: Mute,Enter. Then on the T.V. press "Flash Focus" (it will set it self)
9) Turn off Power.

I have an RCA HD52w59 with a convergence problem. I've been told different things on this site. First I was told to change FL231, CL230, and DL231. I've also been told to replace both IC's (STK392-110)...


Your set doesnt have STK ICs. If the convergence adjustment option has disappeared from the on screen menu, then replace FL231, DL231 and CL230 If the adjustment option hasnt disappeared from the menu then you need to check the resistors on the convergence power supply board some of those will be open. The actual convergence Board will usually not develope problems just the Convergence power supply if the convergence adjustment option is still in the on screen menu.
