The following is the "official" mod from MGA -

1) Parts req'd - two 22uf@50V 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 47uf@50v 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
>>From Pin 11 To Pin 9 Along With The .01 Cap. This Combo Produces Very
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
