Definetly a PIP issue then .  What was your bypass method?    Try this to be 
sure :

MITSUBISHI   #PIP MOD BYPASS

Bypass Method Revised And Simplified!!!!

Jeff Stielau : 3/4/04 : Shoreline Electronics

Remove The Pip Module.

On The Bottom Of The Pc Board , On The Vp Connector

Install A .01uf 50v Disc Cap From Pin 7 To Pin 9 Then Install 4.7uf 35v 
Electrolytic ;Pos.To Pin 5,Neg. To Pin 11

You Can Also Use 22uf 16v Non Polarity Cap For Both..................Many 
Variations In Value Will Work With Reason.

Do Not Re-Install The Pip Module

Some Have Had Luck Just Inserting The Leads Into The Socket...I Would Not 
Trust That Fix In The Long Term...Solder Them To The Bottom Of The Board.
