Vs-45607 Vertical Hold Problem

Big Irish,
Thx for all your postings.
I inherited this 45607 and it takes 10 minutes to stop vertical rolling.
Should I change all 3 regulators and caps or just IC2P01 ?
Can you please give me the part numbers of all 3 regulators?

One of your posts, you say resolder the convergence IC's and the Vertical Output IC. Can you please list the IC Number and location of the Vertical Output IC ?

Thx,
Andy

    Soldering some of the connections stopped the vertical roll.



    Now when I turn the TV on, It seems the screen is slightly squished at top at bottom, about an inch,

    and the colors at the very edge of the band seem to be out of phase. As time goes on, the space gets smaller and smaller, then disappears.

    Is this related to IC2P01/C2P05 ?

    I see IC2P02 is also 9V, Should I change it ? Is it Cap C2P03 or C2P04 or C2P0? ?

    Should I change IC2P03 and its related cap (C2P08?) while I'm at it ?



    Appreciate your Help

    My mitsubishi vs-45607 television rolls all the time. After being on for several hours it will reveal a great picture yet behind what seems like slower rolling. I love the tv and it has a great picture if I could just stop all the rolling. How do I fix this problem?

Bill;

Cause 1
1. VERTICAL ROLLING, VERTICAL BLANKING BAR LOCKING IN THE MIDDLE OF THE PICTURE, ALSO MAY HAVE HORIZONTAL PULLING OR TEARING. CHECK C2C52 10 UFD @ 50 V OFF THE BASE OF Q2C51 ON THE SIGNAL PCB.

2. CHECK C2P05 100 UFD 16 V OFF PIN 3 OF IC2P01 AND IC2P01 PART # 270P466020 (9-VOLT REGULATOR). BOTH ARE ON THE SIGNAL PCB.
Replace all these if they look bad or not. If you can't do it yourself call a service Company and get an estimate, it should cost about $450 if they know what they are doing.
Thanks using FixYa, Big Irish.

GOOD DAY; THE VS-45607 Model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input/device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source) 1. MAY BE INTERMITTENT, SELF-DIAGNOSIS ERROR 23 OR 24. CHECK SOLDER CONNECTIONS AT CONNECTOR "DY" ON THE YOKES. 2. SHUTDOWN AT POWER WITH SELF-DIAGNOSIS ERROR 23 OR 24. CHECK C411 2200 UFD 35 V AND C412 10 UFD 50 V, BOTH LOCATED ON THE MAIN PCB. GOOD LUCK, big IRISH.

Good Day, Delano1981;

It may cure the problem but I would suspect the 9 Volt source
CHECK C2P05 100 UFD 16 V OFF PIN 3 OF IC2P01 AND
IC2P01 PART # 270P466020 (9-VOLT REGULATOR). BOTH
ARE ON THE SIGNAL PCB.

This should resolve your TV"s condition.

Good Luck, big IRISH.

Mitsubishi projection TV VS-4561 Vertical Hold issue


Good Day, Maybeitstime:

Joe the cheapest way is to repair it yourself and this is what you need to do:

VERTICAL 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 ELECTROLYTIC's (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). As you can see this might be over you head but for a 1994 model you did get 14 years of watching TV enjoyment. 'Might think about replacement. Good Luck, big IRISH.

TV screen jumps and rolls, sometimes won't stay on


Try Re-soldering the vertical yoke connection and the vertical output IC. Thats a common problem in that model.
