Question about Mitsubishi VS-45607 45" Rear Projection Television

1 Answer

Hi, Vs-4561 MItsubishi rolling picture

HI, I have the same problem as you do with the mitsubishi vs-4561 and was wondering if you got it fixed or discovered a solution. From what I can see online its the filtering cap that does it (either c7001,c7014,c7026 or c7036) a comb filter to be exact. I would appreciate any more info though! Thanks!

Good Day, pleasehelptv;

Those caps may be the problem but try this:

VERT JITTER/HORZ UNSTABLE-CHECK 'GE' CONNECTOR PIN 5 FOR 1VPP Y SIGNAL INTO PIP PCB THEN CHECK 'GE' CONNECTOR PIN 11 FOR 1VPP Y SIGNAL FROM PIP PCB. IF SIGNAL AT PIN 5 IS GOOD AND PIN 11 IS CLIPPED OR REDUCED. CHECK ALL ELECTROLYTICS (I.E.C7001, C7014, C7026, C7036) AND ALL CONNECTING TRACES TO THESE CAPS FOR CONTINUITY 2. HORIZONTAL TEARING,VERTICAL JITTER. SIGNAL RELATED CONDITION. APPLY FOLLOWING CIRCUIT CHANGES ON PCB-SIGNAL: A. REPLACE R2K8 WITH A 1K RESISTOR (BASE OF Q2B2). B. REPLACE R2K3 WITH A 47 OHM RESISTOR (IC201 PIN 50). C. ADD A 100PF CAPACITOR FROM BASE OF Q2B2 TO JUNCTION OF R2L0 AND R2K6 (GROUND).

HOPE THIS WAS HELPFUL.

Good Luck, big IRISH.

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.

check for swollen capacitors- bad capacitors will cause the screen to roll. If the top of a capacitor even looks SLIGHTLY puffed up, replace it!

I am trying to remove the screen on my Mitsubishi VS-4561 rear projection tv to clean it, how do I remove it? I know it slides up, anyone have a manual???


For my VS-45607 I had to first take off the speaker grill. Then there is a panel just below the screen that can be removed with screws; I removed this just for wire clearance. Then there are a few screws that are along the bottom of the screen that you take off and you should be able to slide the screen up and off. Good luck.

Vs 4561 weak picture


Good Day, Techwanab;

Look for this to be your problem: CHECK FOR OPEN L2C50 PART #325C146030 ON THE SIGNAL PCB, OR BAD CONNECTIONS AND LEAKY CAPS IN THAT AREA.

Hope this was helpful and not too late.

Good Luck, big IRISH.
