Question about RCA D52W20 52" Rear Projection HDTV-Ready Television

1 Answer

D52W20 circuit board

When I turn my TV on, the display is blurry red and blue. I can't even read the words when I press menu ( blurry green ). Until last week the picture got clear enough to view after about 20 minutes. Now it clears up enough to see a non converged picture. When I try a manual convergence the crosses line up but the cross is red, green and yellow. I heard a snapping ( electrical arc ) behind the lower panel. I took off the black plastic lower panel behind the outer panel and can tell the arcing noise is coming from the center circuit board. Is there anything behind the circuit board that could be making that sound, or is the center board bad?

The center circuit board is the green CRT drive circuit. that board could be bad or the green CRT could be faulty. I have access to both those parts for your model

The List & Labels part of the setup lets you edit your channel list and choose or create a

Note: Changing List and Labels can be time consuming. You can change these at a later time by accessing the

Setup menu.

1. Press the left or right arrow to scroll through the available channels and choose the

channel you want to edit.

2. Press the down arrow to highlight the In channel list option. Press the left or right arrow

button to add (the box is checked) or remove (the box is unchecked) the channel from the

3. Press the down arrow to highlight the Channel label option. Press the left or right arrow

Auto Convergence (for models D40W20 and D52W20 only)

move the red cross to overlap the green cross. Press OK when adjustments are complete.

3. The Blue center convergence menu appears with a cyan cross in the middle of the screen. If

it is not, use the arrow buttons to move the blue cross to overlap the green cross. Press OK

I have a Philips 51PW9303 Rear Projection TV that had blue shadows around the sides of the screen and now has a green and red bowed line at bottom. Does I need a convergence board to solve this?


If the following doesn't work the tubes could be at the end of life:
Adjusting convergence:
Note: For best results, the Projection TV needs to be turned on for 15 minutes or longer before adjusting the picture tubes (convergence).

To adjust the convergence of the picture tubes:
  1. Press the 'MENU/SELECT' button on the remote.
  2. Press CURSOR RIGHT to enter the PICTURE menu.
  3. Use CURSOR DOWN and RIGHT to select and enter MANUAL CONVERGE.
  4. Press CURSOR RIGHT to select CONVERGE RED or press CURSOR RIGHT and DOWN to select CONVERGE BLUE.
  5. A crosshair will be shown on the screen. If there is any red or blue fringe around the crosshair, use CURSOR RIGHT, LEFT, UP, DOWN to try and merge the fringe colors with the crosshair.
  6. Press the 'MENU/SELECT' button to return to MANUAL CONVERGE menu.
  7. Press the 'EXIT' button to exit the menu.
If you are satisfied with the convergence you may stop now. Otherwise, you can continue and adjust the convergence more using mult ipoint convergence.
To Adjust multipoint convergence:
  1. Press the 'MENU/SELECT' button on the remote.
  2. Use CURSOR RIGHT to enter the PICTURE menu.
  3. Use CURSOR DOWN and RIGHT on the cursor ring to select and enter MANUAL CONVERGE.
  4. Press CURSOR RIGHT and DOWN on the cursor ring to select MULTIPOINT RED or MULTIPOINT BLUE.
  5. A grid of crosshairs will appear on the screen. If there is any red or blue fringe around any of them, press CURSOR RIGHT to enter NAVIGATE mode.
  6. Use CURSOR RIGHT, LEFT, UP, and DOWN to move to a crosshair that has a color outline.
  7. Press the 'EXIT' button to enter ADJUST mode.
  8. Use CURSOR RIGHT, LEFT, UP, and DOWN to merge the color with the crosshair.
  9. Press the 'STATUS/EXIT' button to return to NAVIGATE mode. Repeat as necessary.
  10. Press the 'MENU' button to return to the MANUAL CONVERGE menu.
  11. Press CURSOR DOWN until SAVE MULTIPOINT is selected.
  12. Press CURSOR RIGHT to save the multipoint settings.
  13. Press the 'EXIT' button to exit the menu.

The picture started to get blurry, after being turned on for 10 minutes would clear up, now just stays blurry and almost no picture at all.


Hi

Thanks for using FixYa. To reset the picture you’ll need to reset all the Video menu options to their original factory setting for which you’ll need to follow this step-by-step procedure---

Press the Menu button and then use up or down arrow button to select the Video menu. Now press the right arrow button and then use up or down arrow button to select Video Reset then press the right arrow button to reset the Video menu options to original values.

If still the problem persists, then you’ll need to check for local interference such as an electrical appliance or power tool and also check the antenna. If required change the direction of the antenna.

To resolve the issue of Blurry Screen, first check whether all the cables from your dish network are fine and connected firmly. If yes then you'll need to pull off the front of the TV, behind the speaker grill there would be a panel. Remove the panel and check for a black box hanging over there. It has 6 controls on it, 3 are marked as focus and 3 as screen. You'll need to adjust the screen. If you turn these too high you can damage a tube. So we are doing real small adjustments. Turn the color off on the TV and adjust the red, blue & green controls up till you get a fine picture. Also adjust the focus until you get a clear picture.

And, if it doesn't resolve your issue then it is an intermittent blue picture tube, a bad blue driver transistor on the CRT board, a bad connection on the blue CRT board, or a problem in the RGB coming from the video jungle IC. A set this age, most likely will run about 300-500 bucks to have this problem fixed, unless it is the picture tube.

Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

I have a Zenith 65 in. TV model #R65W28 serial #271-33220211. The words are blurry and there is a green outline on images in the picture even if i reduce color to black and white. what can i do to fix it?...


It sounds like the convergence drive circuit has gone bad. When that circuit goes the red, blue and green don't line up properly. Have a repair shop check it out. While they are in there have the shop clean the lenses and mirror.

I was just given this t.v because friends couldn't figure out what is wrong with itl. The colors don't line up right,looks kinda blurry depending on the lighting of the program being watched. How do i fix...


According to the manual:
1) go to the "TV Main Menu"
2) Select "Screen"
3) Select Adjust Projection TV (obviously only if a projection TV).
This then allows you to adjust the TV's 3-colors. Selecting GREEN CENTERING brings up a control panel that lets you center the green projection tube on the screen. Selecting RED CONVERGENCE or BLUE CONVERGENCE lets you align the Red & Blue projector tubes. Centre the green projector tube 1st. Then adjust the red & blue until the test pattern on the TV screen appers white.
Good Luck!
