mitsubishi CS-27303 PIP disable
I have this 27" Mitsubishi Tv and I read about the PIP board and have
heard a couple different things. I am interested in trying what this post at the end of the thread here says about disabling the PIP board. If I am reading it correctly I can get rid of the stupid pip board by removing it and soldering a single cap to the mainboard. I don't know why I haven't seen more posts stating this and wanted to make sure it was correct. Also does anyone know where I can get the specific capacitor the guy mentions there? ################################################## ##################### # These are the caps that are known to go bad (some will go bad before others). They are all surface mount types & they a C7001, 7003, 7011, 7014, 7015, 7016, 7020, 7021, 7023, 7026 & 7036. You can usually see where the bad ones are because they will be leaking. Make sure to clean up the leakage because sometimes it will eat away the trace under the cap (which is known to happen under C7001). These surface mount caps can be tricky to remove & if you're not careful you can pull up a trace & break it. If you (or your customer) don't use the PIP feature then you can bypass it by removing the PIP module & soldering a 47mfd 50v bi-polar electrolytic cap between pins 5 & 11 of the VP male connector on the main PCB (I usually remove the VP male connector & then install the cap in holes 5 & 11). Do not just push the leads of the cap into the holes of the VP connecter because it won't hold up long term. Mark # ################################################## ######################## |

Do a Google search on this and you should beable to bypass the PIP altogether.

I just did a PIP bypass today. You need to use 2 capacitors because just
using the one bipolar cap doesn't always work. Desolder the blue VP connector & remove. Solder a .01 disc cap in holes 7 & 9. =A0 Then solder a 4.7/35v electrolytic cap in holes 5 & 11 with the negative lead going in hole 11. While you're at it also ESR the VOUT electrolytics especially the 100uf & 220uf. I usually just replace (unless they've recently been replaced) these because even if they read good they could be on their way out "I have this 27" Mitsubishi Tv and I read about the PIP board and have heard a couple different things.
