    My Mitsubishi CS-35601 has a bad PIP board. Replacing all the caps is beyond
    my level of incompetence, but I think I could handle making a bypass.
    Searching newsgroups and the web I found a few different configurations for
    the bypass and I would appreciate some help in making sure I get it right. I
    pulled the board and found the following identification information.

    The part number on the board is 930B552.
    There is a paper tag on the board with the ID P05010865

    Help in getting this right would be greatly appreciated.

    Thanks in advance - Joel

    The following is the "official" mod from MGA -

    1) Parts req'd - two [email protected] NP electrolytic caps
    2) Remove existing PIP module
    3) Install one cap from pin 5 to pin 11 on the VP connector
    4) Install the other cap from pin 7 to pin 9 on the VP connector

    I Found A Combination That Works To Bypass The Pip 05 Module. Hook Up A
    ..01 Cap Between Pins 7 And 9 Of Vp. Place A [email protected] Elec. Cap Positive
    Lead On Pin 5 Of Vp Plug. Solder The Neg Lead To A 4700 1/2 Watt Res &
    Solder The Other Res Lead To Pin11. Solder A 2700 Ohm 1/2 Watt Resistor
    Good Color & Sync On All Channels.


    Found This One The Sci.Electronics.Repair Forum....Did Not Try It Yet
    But May Be A Good Fix !

    What We'Ve Done For This Model Is To Put A 2.7k And 4.7k Resistor In
    Series With The (-) Leg Of The 47uf Cap To Ground And Tap The Junction
    Of The 2 Resistors And Run That To Pin 11. A Simple Voltage Divider.
    Did A Lot Of Experimenting With Potentiometers To Determine The Values
    Needed. You Could Always Use A 10k Pot To Do This And Would Have
    Something That Is Adjustable. You Will Need About 1.7v P-P At Pin 11
    When Done Instead Of Around 2.7v P-P That You Get When Simply Bypassing
    With That 47uf Cap

    here's another

    Change R7050 1.2k , R7024 1.8k , R7051 1.8k , R7002 1.5k R7034 Should
    Be 0 Ohm And May Already Be That Value R7011 Remove And Discard. R7029
    470k And May Already Be That Value

    Thanks Sidney for the reply. In my web and NG searches, I did find most of
    the references you cited. My problem is too much information. I am not a
    tech and rebuilding the board is clearly beyond my abilities. There are
    several references to different bypass configs that I could probably put
    together but I am not in a position to make a rational choice between them.

    Does anyone know of a bypass fix that WILL work well with the CS35601 with
    all video inputs?

    I've also seen a bypass kit on sale at eBay for $15 from TipsMaster color TV
    Repairs. Does anyone have any info on what this consists of and whether it
    will work on a CS35601? Other pre-made bypasses?

    Another option is to try to find someone to rebuild the board for me or find
    a rebuilt board. Any suggestions?

    I really don't want to put a lot of money into a 15+ year-old TV so am
    looking for low-cost options.

    Thanks in advance - Joel
     
  4. IIRC with the XX601 models you have to compensate for the different input
    and output levels of the video for the PIP module. It is a little more
    complex than a simple cap bypass. Look at the NESDA Ohio site links for the
    specific answers to your question.
