Question about RCA D52W19 52" Rear Projection Television

Blue curves up on the ends and red down

This is for model D52W15 RCA tv. I replaced to blue tube and when I powered it back on the picture looks 3d now. The picture was fine before I replaced the bulb would just blue out and the service man said that it was the blue tube bad. When I use the convergence the crosses line up perfectly. But on the outside edge the blue curves up and the red is curving down. When I take the lenses off the picture is fine. It just shows up as only purple. Any Ideas?

Your going to need to hook up a cross hatch generator to adjust the internal convergence alighnments. Anytime, a tube is replaced, there is alot of alighnment involved with the convergence, and it cannot be alighned from the customers convergence controls. I suggest first you get a service manual, and follow the alighnment to the letter for the convergence. If you do not have a cross hatch generator, then your going to need a test disc(DVD) that has a cross hatch on it. If you do not have access to those two things(cross hatch generator or the test disc) you will need to call out a tech to do this alighnment to the set. They (service tech) don't tell you when you get an estimate for a picture tube that there is some alighnment involved that reguires special test equipment. Thats why they charge what they do. I wish I had better news for you, but without proper test equipment, this is going to be a tough battle. Good Luck Please do not forget to rate this thread.

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both. Repair kits with instructions are also avail from 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 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.

Here are some pics of convergence problems.

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.

Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

Letters and numbers are 3d and curved picture

Hello

red, green, and blue lines curve across the top of tv is cause by defective convergence STK IC or you have open resistor at convergence section. if you have defective RGB Color vertical ramp probably you have defective STK IC..
