Mistubishi tv vertical hold not working

Hi, my husband and I tried to follow some previously posted advice pertaining to mistubishi tvs, vert hold and pip circut boards. We opened our tv only to discover... we don't even know where or what the pip circuit board looks like.

We don't care about the pip feature and simply would like to just remove the pip circuit board to solve the vert. hold problem. Our tv is model # cs-3115r. I'm afraid to clip the wrong brown wire. We are totally amature and just hope NOT to get electricuted when we plug it back in, thanks marnie

I have a mistubishi tv model wd-65737 with bad picture. I replaced the video chip and color wheel but that didn't work....is it possibly that dmd board?..thx


Hi, can you tell me what you see on the screen? It could be a bad cable. Are you using an HDMI cable or the color cables (RCA cables)?

Top of screen disappeared...cant see score of game


The Height adjustment is off... look in the back of the TV set, it has some knobs in the back, one should be vert.lin for Vertical Linearity adjustment, and there is another call Vert.Hgt. for Vertical Height adjustment. try adjusting the Vertical Height first with someone watching in the front of the big TV to see if the top comes back into view, you might have to adjust the knob very slowly one way then the other way, to make this adjustment. If it doesnot adjust take it to a TV shop to get it repaired.
Good Luck.

I have a WS 55859 and after power outage i got the green POWER light blinking. I replaced all seven capacitors 1000uf but i still can't switch it in? Any other advice? Rgds FM


If replacing the 7 caps doesn't work I then try to re-solder the small 8 pin ICs. Be very careful and try to avoid cooking it or leaving a solder bridge. If that doesn't work either you'll have to replace the DM-POWER board. You'll beed a Mits authorized service center to order the part. Goodluck.

Our tv worked fine last night and now at first it was really dark and now it is flipping. What do I do?


The loss of brightness is probably caused by degraded high-voltage internal to the set. This can be caused by an electrical "brownout" that will correct itself.
The flipping problem is due to a degraded vertical synchronization signal. First make sure you have a strong signal - no loose antenna/cable connections, etc. Assuming you have a strong signal (i.e., no "snow"), analog TVs sometimes have a so-called "secondary control" (labelled "Vertical Hold", "VH", "Vert", etc.)located on the rear of the set. If you are lucky you may have one and be able to adjust it and regain stability.
Old sets used analog components (which age with time and are somewhat heat-sensitive) to control the vertical sync. Modern TVs use digital signal processing techniques that need no such controls.
Probably need to take the set to a repairman, if you can find one.

Intermittent vertical jitter on mistubishi tv 65000


Good Day, sdkhanmd; Replace C2P05 100 UFD 16 VOLT off pin 3 IC2P01 and IC2P01 part #270P466020 (9 volt regulator). Both are on the signal PCB. Also, check other caps in area for leakage. Hope this was helpful, this common for this model. Good Luck, big IRISH.

Vertical adjustment


I got your previous post. normally, the adjustments are toward the back following the back side of the main board, if they are not there, then they are sprayed all around the main board itself. things to look for are:

vert.
vadj.

I'm looking for a service manual for your tv 27pt9015d. still not having any joy finding this manual. the problem you are experiencing is technically called "vertical fold over", if there is no adjustments, then it's circuit controlled and will probably need servicing.

Rolling screen


This may be a vertical hold control problem I'm not sure where the Vert. Hold potentiometer is on the mainboard. I would see if you can find someone who can locate it and adjust it.
