    I'm a retired police officer/CET. Formerly repaired and installed communications equipment for DC Police and the Uniformed Division of the Secret Service. Is there a manual/schematic for this unit available anywhere other than the Library of Congress???

If you are using aerial reception, and the vertical roll is not on when watching DVDs , then just use a signal booster like this one, Motorola Signal Booster 1-Port BDA-S1 ..., that will stop vertical roll.

The rolling is caused by a distortion in the video signal somewhere in the signal path. This can be caused by a defective PIP board. These are known to have problems with surface mounted capacitors. There is a "repair kit" available for this from MATELECTONICS.COM for about $14. If you can solder surface mounted capacitors, you should be able to resolve this yourself. Try installing the repair kit onto the PIP board and update this if the problem is not resolved. Please note that ALL video signals pass through the PIP module whether or not PIP is activated.

Hi there.
The TV may just have to be reset, you will find the reset button on the left hand side of the TV's control panel, you may have to use a paperclip to push the button.

Good luck and thanks for using FixYa!!

Here are my two suggestions:

ONE: Do a hard reset. Maybe twice. Unplug the power cord and leave unplugged for 4 hours or overnight.

TWO: Give it the whacking test. This will tell you if you have loose connections or cold solder joints acting up.

http://www.neato.org/~page/mitsu/service.html

The above site is a procedure on entering into the service mode for Mitsubishi sets..... although yours is older, it may still have similar functionality. If not, there are other service mode sites on the internet - just do a goodle search for them.

I am sure the problem is related to convergence and/or deflection circuits, but I think a diagnosis with hands-on experts will be necessary.

If we knew what the exact problem was, you could probably fix it by yourself.... But I have not experienced this symptom before and I cannot find any reference to it in the outer world (internet).

All repairs on big screen sets are expensive. I would never recommend repairs on a set this old. If you want to fix it for the reasons you stated, go ahead, but statistically speaking you should expect other failures to follow soon thereafter - sorry to say...

Thanks.

    Horizontal lines means the vertical deflection system which is supposed to blank them out during retrace is not working.

    Various schemes are used to control this blanking functions in modern tvs. Years ago it was always the blanking capacitor and they were clearly labeled as such on the printed boards. However, nowdays the blanking if often a software function contained with in the workings of one of the IC chips.

    I cannot find a schematic of this unit so I cannot, therefore, give you a specific identification of the process used or the blanking components employed. However, a few Sony and Mitsubishi sets that I checked have the function integrated within the jungle chip; this is the one that processes the video signal and generates all the chroma signals within the tv prior to them being fed to the picture tube drivers.

    My suggestion is to have a tech do the job unless you want to spring for a service manual and try it yourself. The service manual will cost about $25 - unless you can buddy up with a local shop that will let you look at theirs and help identify the components on the board.

    Good Luck,
    Taran.

    Disregard the old one...



    The correct link would be

    The schematics would be the same for most of the models.

Hi, This is a vertical hold problem.
You can try connecting the Cable to directly the RF input jack on the TV.
If it doesnt work, there could be a problem with the power suppply unit which connects to the tuner section inside the TV. Probably replacing the filter capacity in it would work.
Good Luck :)

Hello,

This can mean that the vertical sync pulses are too low, hoever this is highly unlikely, so the other point could be that the vertical oscillator is malfunctioning.

    This model has vertical hold adjustments but I am not sure if they are on the front panel or the back panel or the on-screen menu.  Since the set is old, it could be anywhere.

    If you cannot find it, let me know.

    When you do find it, just adjust it when the set is first turned on until the picture locks in.

    Let me know if you need further help.

    Thanks,

The picture on my TS-4573 rear projection tv has started to roll vertically at a fast rate. How can I make this stop. On old tv's there was a vertical hold adjustment on the back that you could play with...


this fault is caused by defective electrolytic capacitors in the vertical deflection circuits, they need to be changed out, do this before it causes more problems, there are no adjustments for this anymore.

I cannot find vertical hold


The sync is automatic. There are no knobs to turn. If the picture is rolling, look first to the source connection and make sure your tv has a solid vertical sync connection. If you are using the RF input then the issue could be within your small signal board also known as the SSB. Good luck.

Picture rolling when I first turn on my tv


A rolling picture or loss of vertical sync can be caused by several components including a bad signal board or jack panel assy. You will not be able to resolve this yourself. contact a Mitsubishi authorized service center.

Vertical rolling of picture


If the picture rolls while both on cable as well as when you playback a tape or DVD, it could be caused by a bad filter capacitor in the power supply or vertical deflection circuits. If it only rolls while trying to view a picture from a cable/satellite box, then that component is likely at fault.

Picture flipping


The P52940 uses the 195 series chassis. The vert/hgt control is for vertical height. It adjusts the size of the picture from top to bottom. If your picture is flipping, it most likely means that something is wrong in the vertical circuits. I have seen fluid leak out of one of the CRTs and drip down on the vertical output IC, causeing the picture to go crazy vertically. The set should be serviced by a qualified tech experienced in the RCA 195 chassis.

Picture is Rolling..stops after some warm-up


I have seen this many times. There is a 9 volt regulator on the small signal board that causes this. The regulator goes bad and the 9 volts starts dropping, especially at start-up when the regulator is cold. If the voltage is below 8 volts then the picture gets dark and the vertical becomes unstable, with the picture squeezing down and/or rolling. As the regulator warms up the voltage starts rising back towards 9 volts and the symptoms start clearing up. There are 3 regulators in a row on the board and the regulator in the middle is always the bad one. Replacing that regulator should cure your problems but it should be replaced by someone experienced in servicing Mitsubishi projection TV's because pulling the chassis out is quite tricky.
