Color is not alligned

it will be ure convergance chips they are about $30 each and u need 2 also dont try and realign settings as it will stuff settings and when u put new chips in it is a very long process to realign, open the back and you will see the ICs they have about 40pins and screwed to an alloy heatsink, if its pretty old its not worth fixing for the price of these units these days second hand on ebay

Green & Blue Ghosting Convergance problem

Odds are real good that the cooling fluid in the green and blue picture tube assemblies has become contaminated. You can tell by looking down into the lenses with a flash light. Funny thing is the red never gets contaminated because whatever organism is causing the problem can't survive in red light. BTW this may still not solve all of your convergence problems but when the colors are so badly diffused the convergence sensors for flash focus can't lock onto the beam landing.

Color ghosts out of allignment

This is a convergence problem that can be as simple as poor connections on the pins of the convergence ICs or defective ICs. If you can solder and are comfortable working inside the set where there are potentially dangerous high voltages even when unplugged, you can fix this yourself.

Let me know if you wish to attempt the repair and I will post additional details and instructions.

Rca r52wh74 - no auto convergance

Go to menu then setup look for convergence if it is missing on menu then you have a open FUSE/ FL231, But if you have convergence on menu then go into service mode turnTV off then PRESS and hold at same time ch- and vol- wait for set to come on then release TV should now be in Factory settings.

My red convergence is out, and it will not change

when thes tvs get around 4 to 5 years old the convergence go's out on them there are 2 stb's or someting like that it may be stc's i can't remember what they call them it's been so long sence mine did 1 has probbly went bad i chould control the red but not the blue and sometimes when this happens it will also blow green fuses as well in my books they should put cooling fans in these tvs to help cool them there is to much heat inside the tv thats why they only last a few years before having that problem i have 3 of them and all three of them did the same thing you can check the remote eye on the front of your tv sometimes when there is a problem the green remote eye will flash acode but you will have to have the service manual to find out what what the code means

Blue Convergence just went out?

High Voltage Capacitor? Leave the set unplugged for 1/2 hour most components will selfdischarge, as for your problem, being a Magnavox, you have one of two problems, the convergence I suspect is what is blown out, this unit probably uses STK392-110 Ic's, I would suggest replacing with STK394-160e chips as they are probably shorted, some of the big resistors (1 or 2) may be opened up also, usually they change color. The only other thing that would cause usually a yellow color in the corners is the CRT Fluid, it changes from clear to Orange in color and clamps off the blue color from the fringes, I suspect the chips need replacement, dont forget to put some heatsink dope behind them, they are usually on the left in the front of the set (from the back) Big long heatsink that is fairly tall (probably the biggest heatsink in the set.) Good luck, and the repair usually runs around $350.

Is it my Convergance??

Do not try to align the colors with the remote. One of your convergence IC's has gone bad and needs to be replaced, possible burning one of the 3 low value resistors next to it. If you change the convergence settings now then they will have to be reset when the new IC is installed.
