# Misconvergence Specifically, how would someone go about doing a convergence setup on a RCA P56940 56" projection tv? There is problems with both vertical and horizontal alignment. The three colors and separated and the picture has a concave arch to it both top and bottom.

My picture appears to be concave.

The colors are misaligned and the picture has a convex shape,

Specifically, how would someone go about doing a convergence setup on a Panasonic 56" projection tv? There is problems with both vertical alignment. There is a blue color separated and the picture has a concave arch to the top.

It can be done without Chipper check. Go to Parameter 80 and it can be done .First correct any green geometery. Then work from there. All this is covered on the ptk 195 cd

Convergence on RCA P56940 chassis PTK195 can only be done by service center with RCA Chipper Check computer interface box. Sounds like possibly missing -15 volt or +15 volt supply to digital convergence circuit, bad i.c.'s U19503 or U19504. Supply voltages come from regulator supply transformer T19701 diodes CR19707 (-15 volts) and CR19709 (+15 volt)

### Hi, I own an RCA HD56W58 TV and just replaced the Deflection Board as well as the HV Block. Everything went well but, when I tried Auto Convergeance, I get message, "Sensor Unresponsive, trouble shoot...

jvalen3070,

This may not solve all your problems because the adjustment you are talking about is a course adjustment only and does not tweak the alignment across the entire screen so you could still have areas of misconvergence. It would be better to correct the problem. Your unit either has a problem with the sensors located around the perimeter of the screen or the convergence circuit. If no wires are disconnected from the sensors, and this is the most likely cause, I would change the convergence ICs. I have a tip at http://www.fixya.com/support/r4220499-change_projection_tv_convergence_ics which explains the process. If changing the convergence ICs does not solve your problem see my tip at http://www.fixya.com/support/r4273935-replace_digital_convergence_box for additional troubleshooting.

Thanks for usiing FixYa and for the great rating.

### I own a RCA d52w20 and the convergence is terribly bad. I set it up, used auto convergence and even went to the service menu for the 25 point setup. But my screen is still terribly bowed and i cannot find...

Try this with TV off Press and Hold CH- VOL- at same Time Hold untill TV comes on.
Then you should be in Factory setting menu, it will either corect the Problem its self or go straight to Service Menu for Techicians.

### I need a convergence kit for a rca 52 inch rear projection tv

what type of problem with convergence? no convergence at all? pitcure bowing? this in the setup menu do you have the convergence option? a convergence ki in a standad porojection has stk ic/s this model does not .you might have the fl231 fuse problem.. generally its board replacement. then the problem becomes alighnment.

### My RCA model P61929 picture is curved inward on the top and bottom

Is there also a misconvergence? If so you need to replace the convergence ICs. I have a tip at http://www.fixya.com/support/r4220499-change_projection_tv_convergence_ics which explains the problem, how to correct it and where to get the parts. Let me know if you need more help. Thanks for using FixYa and for the generous rating!!

### RCA 52" Convergence Problem

Replace the convergence power supply. You can get the ITC222A convergence power supply board at the following link under RCA circuit boards.

### D52W20 red convergence problem

Do you see in Menu go to setup look for convergence if it is not there you have a open fuse 400ma FL231. Try This place for Parts http://servicemanuals.vstore.ca Let me know if you need anymore help.

### Convergence problem on rca model d52w23

Replace convergence board or repair it. Try this with TV off Press and hold vol-and ch- at same time hold untill set comes on Now you should be in service menu Go to convergence Adjust the 16x9 mode.

### RCA HD52W59 Projection Big Screen TV

This problem is commonly refered to as a CONVERGENCE problem. Question 1 do you have convergence seting in setup menu...if you do NOT it could be a special small fuse. 2 if you go into setup then convergence. then can you move crosshairs in setup. Since you have a arcing picture this indicates convergence power supply problems....in which has to be replaced or repaired,

### My RCA Tv has a concave picture!!!

Convergence problems. FIrst try going into customer setup and seeing if convergence options are there and if adjustments can be made. unfortunately when the picture is bowed like that it idicates a complete loss of convergence which idicates one of three boards have gone bad.

### Television problem

The yellow is being caused by misconvergence of the red and green beams. Go into the menu and do a convergence setup. Should be under video or convergence heading. Your ops manual should tell you exactly how. If after setting the convergence you still have the problem your digital convergence box is bad and you will need a tech to replace it. About \$60 to \$100.
