Question about RCA P46924 46" Rear Projection Television

1 Answer

Convergence problems We can not get the convergence to line up at all. When we try the problem keeps getting worse. The grid looks bowed. Is this a problem that can be fixed? Do I need a part to fix it and is it expensive?? Thanks, Linda

This set might have a convergence power supply that could be out, might have another issue, I suspect something in the power supply on these.

There are 3 distinct color lines and the picture looks 3d. The lines are bowed and trying to adjust using the convergence grid doesn't work- the grid is bowed


Mitsubishis are notorious for bad solder connections on the convergence IC's. These are located on the big heat sinks on the main board. It's an easy fix if you know how to solder. Check for any play on the IC's when "wiggled".

I have a Mitsubishi WS-65809 Rear projection TV the fisheyes or bent screen.


Try to describe problem better----is picture concave or bowed with colors out of place or is is just not straight?

If in doubt go into customer menu and select convergence and then advanced(instructions will be on screen) it will bring up a grid of lines--what you are looking for and I need to know is is the grid not square or are there red or blue lines with or without a bow in them?

The more you can tell me the better the chance I can help you--I am in California and will be here for the next few hours.

Our hitachi has horizontal lines across the screen first it was just a small area now it half of the screen what could be causing this?


I have a suggestion that will tell you and me exactly what your problem is--Does set have small button on front that says MAGIC FOCUS? If it does press it and after it starts press it again--it will stop the magic focus and bring up the convergence grid on the screen----you will see a grid of lines and just need to look at them----if red or blue is out of place you have a convergence problem--very common on this kind of set.

If set does not have MAGIC FOCUS BUTTON (IT IS ON THE RIGHT OF THE KEYBOARD AND MAY BE RECESSED) You can remove the front speaker grill and the inspection plate behind it----there is a tiny small push button switch on the left front of the circuit boards--it will have blue button--us something not metal (I use a eraser end of a pencil) this will engage the set into the same convergence mode.

You just need to see what the grid looks like--if it is skewed etc--YOU KNOW YOU HAVE A CONVERGENCE PROBLEM.

If it is a convergence problem I CAN TELL YOU WHAT IS INVOLVED TO REPAIR THE SET---it will depend if you can do it yourself or need to have someone do it for you--most of this repair is just getting at a few parts and being able to do good soldering etc.


Try to check to see if you actually have a Convergence trouble or something else--if the lines on the grid are not white--red or blue bowed or out of place anywhere--it is convergence problem.

Seeing is believing and if you see the grid looks bad.


let me know--I am here to help people---I HAVE FIXED HUNDREDS OF HITACHI SETS WITH ALL KINDS OF TROUBLES--CONVERGENCE IS THE MOST COMMON PROBLEM--BY THE WAY: CONFIRM THAT ACTUAL MODEL NUMBER IS 51F500.

Problem #1 - CONVERGENCE PROBLEM

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 projeciton 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 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

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

Mitsubishi ws-65809 Convergence will not align correctly


You may also have a resistor burnt out for the convergence ICs.. They are all right in front of the ICs and will usually show browninsh if burnt up. If bad, replace the pair and maybe the ICs as well if they've failed again. If your new ICs fixed the lines so they'll move, then you may have problems with the centering magnets on the yokes of the crts. Dont move the yokes or magnets if you can help it, but look to see if some of the manufacturers glue broke free and let the magnet spin around the neck of the tube. If so, try to put it back where it was and then re-converge.

Sudden discoloration, ghosting, bowed horizontal lines in top and bottom of picture


The convergence ICs probably have a cracked solder joint on the foil side of the circuit board. Re-flowing the the solder would help. I will always replace the convergence ICs when doing this job. The labor remains the same and you will have to pay a few extra bucks for the parts. To fix this yourself, you will need to be able to identify the two convergence ICs, have a basic knowledge of electronics and be able to use a soldering iron. You will also have to do an alignment through the service menu.
