Question about Proscan PS52800 52" Rear Projection Television

1 Answer

Auto Convergence failed becuase PS52800 failed to detect one of my Sensors?

Hello~ That is the message I get when I try to execute auto-convergence. It fails to detect one of my sensors whatever that means. It also recommends making the room darker and trying again. That's not it. I don't notice a color problem though, if that's what convergence is. The model is RCA MM52100 from 2001. It has a serious overscan problem (top and bottom), the picture has always been too dark, and it's out of focus at the perimeter. Otherwise it's wonderful. Can someone point me in the right direction? The set is watchable, so I don't think it's too major. I'd like to get a picture that someone might buy so I don't have to pay to have it hauled away. Anybody? Thanks.

The overscan would certainly cause auto convergence failures since the beam the CRT's shoot out are on the corners and upper center and lower center. Being too dark can also cause issues since one of the CRT beams might not be bright enough for the sensors to register. I would first have someone adjust the vertical size if the top and bottom of the frame are somewhat cutoff.

I can't adjust my convergence LG RU56nz23

If you have already tried auto convergence under special in the tv menu and still cant get it i had your problem.

One of your convergence sensors is dead and you have to replace it if you have no experience with this kind of problems call lg and tell them your model and that one of your convergence sensors is out ask them for a tecnician they will charge around 30$ for the tecnical visit and some extra for the repair

P.S your model has to have this line in it (-) (ru-56nz23)

Screen is pinching

you may still have a fl231 fuse type problem. I would first suggest resoldering the flyback connections. dince this happen ever so often it possible a connection problem. If i had it in the shop i woould chek the flat ribbon connectors also. convergence is controled by three board, convergence power, convergence amp and small signal board. since it pinches this is indication of interuption of convergence power supply. the auto convergence not working. is a symptom of small signal board issues. the small signal board requires specal interface equipment to download data off to place on new board. or the sensors arond the screen has failed.

Convergence prob for d52w26 rear projection tv 52"

If the auto-convergence is not working then the convergence amp ICs are starting to fail. If you can solder, try resoldering the pins on these ICs. If that fails to resolve the problem, replace the ICs. These are large black ICs attached to a heatsink and should be marked STKxxx.

Keep us posted.

Sensor not reading problem is due there is some obstruct between sensor and projected light beam. Check any disturbance are there and clean the sensors. Cleaning work is done by the technical persons only since it is sensitive area. Try another method also by changing the TV aspect ratio is 16:9 and then select auto convergence method. This is the one chance is there before you call the technical person
