    Yeah, I tried that first thing. Nothing happens. Is there a seperate tuner for the pip than the main picture?

Try swapping the pip for the main picture...

    No, both the chroma and the luma circuits pass signal through the same tuner - through the PIP - and onto the large signal board. Without some signal tracing it would be impossible at best to determine where the video signal loss is happening...

    That is a V17 chassis, same unit as the WS-xx907 and WT-46807 and nothing on the ASC (Authorized Service Center) site has any tips or bulletins regarding this issue - so I think you'll probably have to bit the bullet on this one and take it in...

    It could be the signal processor, could be the DM, or more precisely the E2P module in the DM or it could just be poor regulation. It will sure give some tech a challenge and a welcome break from the routeen bandaide fixes... :)

    Hope this helps!

Can not get pip to work

Pip has its own tuner, try getting a cable splitter to split the signal into the tv. If you have digital cable you may need a second cable box to do this. If your cable provider still sends an analog signal the splitter will work.

Hi i have a 93 Mitsubishi model# ck35402. I was told that the pip had went out. was hoping someone could walk me through on how to remove and reroute

From the bottom of the main board locate IC 2004 between the PIP module and the tuner. Remove the jumper between pins 2 & 6, then jump pins 6 & 7. Next , pull the pip module from its socket and toss it. The symptom for a bad PIP module could be black screen, no picture, blue streaks, wavy or jittering picture.The audio will not be affected. Make sure the symptom fits the cure before you bypass the PIP. Good luck!

This is a common issue with HDMI. Try unplugging the TV for 2 monutes and also reset the cable box as well by inplugging.

No main picture, PIP ok

There is a repair kit, for the PIP module, as thats where your problem lies. if you know how to solder on and off surface mounted capacitors, its a breeze to do, but if you dont, you will most likly put to much heat on the board and the landings and printed circuit traces will come up, so if you decide to do this yourselfs, please be carefull. The kit is available at this link. If you do not feel comfortable do this, maybe you know someone whos an electronic hobbiest and can replace these for you .. Good Luck PS please do not forget to rate this thread.
