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.

"Y motor failed to home" error message on auto refractor/keratometer model 599

This means that there is a sensor in the unit that cannot detect the Y axis stepping motor location at startup. This unit is very delicate and needs to be serviced and recalibrated. It wont be cheap to have done.

IRC4080i printer. How do I correct error code E000007-0001?

Error Codes Relevant to Fixing/Pressure Belt Displacement Control

E007 Fixing belt displacement error

0001: Upper belt displacement fault. (Either the upper belt full displacement or the belt displacement sensor


0002: Lower belt displacement fault. (Either the lower belt full displacement or the belt displacement sensor


0101: Upper belt HP detection error.

0102: Lower belt HP detection error.


Adjust the fixing/pressure unit HP with the following service mode at the installation or when replacing the

fixing (pressure) belt.


Points to Note When Replacing Fixing Unit

By executing the service mode, the alarm code is closed and the total rotation time is cleared. Thus, this mode

must be executed when replacing the fixing unit.

If the mode is not executed, the following symptoms will occur.

-The alarm code is not closed.

06-0002: Fixing unit life alarm (Caused by the belt displacement)

06-0004: Fixing unit life alarm (Caused by the torque up)

-Although the total rotation time of the replaced fixing assemble does not reach to the message threshold, the

machine wrongly recognize that it reaches to the threshold and displays the message.

Be sure not to execute the mode except at the installation and the fixing unit replacement. If not, an error
message may not be displayed when the fixing unit reaches to its life.

Service required

This message is generated only after a Bel or Escort radar detector has repeatedly encountered problems while trying to self-calibrate its radar detection circuitry. The Service Required message literally means that you must send in your RD for service since there is nothing that can be done to fix whatever the problem is short of sending it in for factory service. At least it will come back working like brand new!

Auto Converge

If the message "sensor is unresponsive" crops up then the problem is definitely electronic and lies somewhere in a loop that starts near the tube base, goes to the main board and back to the tube base. However, you can try to do a manual converge by adjusting the ring permanent magnets on the neck of the tube (right behind the scanning coils) while something is being displayed. Normally these magnets are secured with a clear glue to minimize drift. Use a heat gun to soften the glue and then turn the ring magnets around until you are happy with the picture. As you know, this part of the TV has some pretty dangerous high voltages so try to keep your left hand in your back pocket while doing these adjustments with your right. Good luck.
