Resolder the fingers on the edge of the power supply where it goes into the main board edge connector.

How do I adjust the convergence properties on an RCA rear projection tv?


Normally on the RCA rear projection TV's you would bring up your menu and choose the Setup menu, then press OK on the remote. That menu would then have Convergence as a choice. Once that was chosen the next menu would give you the choice of either letting the TV run it's own Autoconvergence program, or you would select either Red or Blue convergence.

Choosing Red Convergence would bring up a Yellow cross-hair in the middle of the screen. If the Convergence was not correct you would see separate Green and Red cross-hairs. Once they were perfectly aligned you would again see one Yellow cross-hair.

Choosing Blue Convergence would bring up a Blue cross-hair in the center of the screen. If the alignment was out you would see 2 Blue cross-hairs. Using the Up and Down and Left and Right cursor keys you would adjust the alignment until a single solid Blue cross-hair was in the center of the screen.

Tried to auto adjust the guns, will not come within range


Hi Tod,

If colors do not align correctly, most likely you have a convergence failure. This requires replacement of the 2 STK ICs and possibly some low ohm resistors.

Some Toshiba have a Horizontal oscillator/Drive IC failure that results in a small or shrunk picture (2-3" border on all sides). The 3 colors do not align properly because of the reduced Hor drive signal. The convergence adjust controls will work but not allow good adjustment. Convergence is ok, Hor Drive signal is incorrect.

Many do-it-yourselfers mistake the Hor Drive problem in Toshiba RPTV with convergence failure. Too much adjustment of the convergence controls may cause the saved data to be really messed up and require more difficult alignment in the service mode.

If minor or simple adjustments in the customer convergence adjust menu do not fix your problem, there is a fault. Stop adjusting until fault is repaired

Convergence failure can be accurately identified with the Convergence Gallery on our website. Service in Toronto, Ottawa, Calgary, Edmonton and other Canada cities.

All colors are out of alignment. It is fine but after watching it for about 20 min. It will fall out of alignment


The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

GE 60in Big Screen(Convergence won't Align)


do you know how to solder? If you do you can redolder the two convergence IC's on the convergence board and it will probably cure your problem. These IC's usually are against a large metal heat sink they stand up and have quite a few pins on them. If you try this you need a pencil solder iron and solder and do not solder any of the pins together.

Red arching lines


is this that you are adjusting called convergence? If so then if it's really bad you can try to reset convergence, if not then the red needs to be aligned up with green first then blue on green. Can you provide a picture of what it looks like?

RCA P46159 Convergence


Why would the set go out of adjustments? I highly doubt if the set needs only alignment. These adjustments are for small drifts only. If anything is way out more then what the on screen can adjust, you have a problem with the convergence correction circuit. There is a convergence power supply in this set that goes bad a lot in these TV sets. There is also a convergence driver board. These RCA sets do not have the integrated IC's like most sets do. Each convergence yoke, horizontal as well as the vertical, has two independent power amp circuits driving them. And that's for all there tubes. So there are 6 separate amps controlling the convergence in these TV sets. You really should call in an RCA authorized repair shop to assist you in this repair. Good Luck

Convergence setup menu gone


No rest on this model other than unplugging to let it return to factory default. If your a tech .. Check R19722 and R19703 for open. Both 750 K. these open make the convergence menu to be gone.
