Rca d40w20 tv convergence and power on problems

Am unsure if my comment made it to you. you answered my convergence question but i live in nowhere arkansas and wanted to know if replacing both of the fuses you spoke of was a possibility. i only ask because i am sure it would cost me more to find and use a tv repair man than to buy i new tv. thank you for you help

It is possible, if you do not have experience in fixing tvs is better replaceing the whole convergence board.

You should be able to find parts here.

I have an RCA D40W20 HDtv with the same 3d looking convergence problem. Is mine as easy to do as the Sony KP-51HW40 solution from 2 mnths ago?


All projection TV sets have two very common problems. One is convergence ( 3D/Warped video or dead set) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

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. In some cases the TV will also not show any video. 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, wavy, or has a shadow or shadows
  • 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.

The coaxial cable antenna broke on my RCA tv


The part is called a Female Belling-Lee Socket. Radio Shack, or anywhere that sells antennas, CB radios, repairs TV sets, should have one. Soldering it in, is another matter. Be careful.

Rca d40w20 tv convergence and power on problems


The problem is most likely due to a defective convergence IC.

There are two convergence STK ICs located on the convergence board.

You need first to test the ICS, by checking for continuity the pico fuses at the base of the ICs, then replace the faulty STK.

You should trying doing it yourself only if you are a proven electronic repairer.

Problem


This is a terrible thing to tell you, but, what you describe is called dijitizing then the light engine failed Now it gets real bad ,,, This part 261589 is about $590.00 and is on factory backorder with no ETA in site. We have been waiting for one of these at our shop now for over 5 months. RCA knows about this problem and you might want to give them a call and see if they will do anything

No convergence


Usually when that happens it is related to problems on the deflection board a diode or fusible link has opened making the set act like its a direct view thereby having no convergence option. It will take an experienced tech to properly diagnose that problem.
