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

RCA D52W136D blurry screen

Recently the screen started to go blurry, msaligned colors. It continued to worsen. Adjusting convergence helped a little only to misalign shortly after. The Picture has started to blink random hues of red, green, and Blue in the screen. The timing and color seem to be random. Convergence is still an option in the set-up menu which leads me to believe the fuse (referenced on this site many time) is fine.

Basically looking for a ballpark estimate would be. Had a repair guy scheduled to come out after the new year but don't want to pay the $105 charge to look at it if the repair is more than likely going to be more than $400. Thanks in advance.

This is a rear view projection television. Inside is a projector with three lenses (red, green, blue). The projector only has a fixed number of hours in it's lifespan and then it dies. You either need to replace the bulbs, or replace the projector. Both options will most likely be more than $400.

Your technician shouldn't have to come out to your house. The back panel can be removed from the TV, and the entire projection unit slides out on rails. You can put that in a car and drive it wherever you want to get it repaired. That might save you some money.

The colors are separated. Images are blurry and


Try adjusting the convergence. If it won't move see below- (or hitting Magic Focus for some Hitachi’s)
This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$400 Be sure to vote/rate me if this helped Thanks!

Hi there I've noticed youve been really helpful so...


The )( is indicating your loosing High voltage required to pull the raster across the screen. This can be tweaked but a short lived solution. I suggest it may be a good time to start shopping.

Samsung Rear Projection Problem (not convergence)


The tv has 2 focus adjustments for each tube, mechanical and electrical.

1. Mechanical focus is set by looking at screen from back (through inspection plate on back of most samsungs) and rotating the lens assembly on CRT. loosen wing nut and turn lens assembly to go through focus and back to best position.

Put convergence pattern on screen and manually misadjust bottom red and green lines convergence so they can be seen through inspection hole.

With back cover of TV off you can usually reach your hand up beside the lens assembly to loosen the wing nut then rotate to adjust. Green is in the middle. The focus will be obvious when you rotate and look

When you are finished make sure the foam dust protector is not over any of the lens assemblies and the wing nut is tight.

2. Electrical focus - located at front of unit. the front grille/speaker cover is removed and maybe a cover over the front crt inspection hole.

In the inspection hole there is a black plastic "Focus/screen adjust Assembly" with 2 rows of 3 controls.

One row is focus and the other is screen. The middle controls are for green with R/B on either side. Usually the controls are labelled as "focus" and "screen". You want to adjust the focus controls, one for each color. Look for the focus or screen label imprinted in the plastic. Don't play with the screen settings.

With the same misadjusted convergence pattern you can see a red, blue and green line. Adjust green focus and watch green line for best focus. Do same for other 2.

Screen adjustments are very exact and delicate. The easiest way to deal with them is to turn color off in Customer adjust menu. Put any color tone adjustments in the middle (low, med, high, put at med).

You should have a b/w picture if there are no crt or other color related faults. If it is close to B/W leave screens alone.

If the pix is too green, then the green screen setting must be reduced a small amount. Do not play with these adjustments as most TV repairrers have a difficult time adjusting them.

If focus adjustments don't help then focus control or CRT may be defective. Needs expert to determine.

Cant get convergence board settings


I suspect that the convergence board may be defective. If the convergence was okay before and then went out, this is a fault and not an adjustment! Adjusting only compounds the fault.
Look up the Sanyo home page on the net, and get their tech support. You can order a new convergence board, and the service manual to start.

It may be more practical for you to let their authorized service rep service the set for you. It is possible that you start buying the parts, and end up needing to troubleshoot for more faults. You will need the proper tools and training to get involved in troubleshooting your set.

Convergence Help please.....?


The collar adjustments on the top of the crt assembles are simply focus... If you have never removed the crt's it is HIGHLY unlikely you will need to rebalance the crt in your endeavor to set convergence....
Next - never, never, never use some intervention signal to set convergence... Did I get enough nevers in there... Hook up a dvd player or good vcr and start with that as a picture... Set yor collars if they need adjusting.. At this point, and from what you've described just readjust your blue collar back to what you had...
Next, go back into the multi-point convergence and check to make sure you have each quadrant set to as close as you want... Then bring the picture back up and re-check.. If there is any ghosting when you hook this back up to your sat box or cable guess where it's coming from.. You got it, garbage in - garbage out...
With the digital convergence on that unit there is no need to jig the set. (ie: use a string to find center...) Some set require an overlay but their multi-point isn't nearly as complex as that unit...
In short, if your colors align to a white cross you got it!!
