John,
From Tech Repair CD:
Mitsubishi\CS35707\NO VIDEO\\\\1. CHECK IC6F01 PIN 8 (BLUE)* PIN 6 GREEN* AND
PIN 5 (RED) FOR 3VPP SIGNAL
IF MISSING CONFIRM 3 VPP INPUTS AT PINS 1*2 AND 3\IF PRESENT. REPLACE IC6F01
PART # 272P027010. AND ADD A
DIODE (1S2471M) PART # 264P045040.\INSTALLED WITH THE ANODE CONNECTED TO THE
ANODE OF D6XA1 AND THE
CATHODE CONNECTED TO THE CATHODE OF D6F04\\\\\\
MITSUBISHI \CS35607\No Green {Possible Other Two Primary Colors}\\\\Ic6f01or
Ic6h01 Both An5862k\Then
add this mod to prevent recurring failures. Add A Diode (1N4148) Installed
With The Anode Connected To
The Anode Of D6xa1 And The\Cathode Connected To The Cathode Of D6f04. You may
want to look closely for a
lifted trace or pad....the connections on these IC's are small\\\\\\
