Konica 4345 with 43-1 code

[nmfaxman]

I have replace thermistor.
Lamps and thermal fuses check.
Wiriing checks.
I can run 50 copies no problem.
New heat roller.
All lamps light.
It sits for 5 minutes then it codes out.
This is a church that has little money.
I am going to take a massive loss if I can't make it work.
Any input??????
I have the manual and schematics just at a loss as to what it is.

You have probably already this but here it is:

Description:
F43 displayed shortly after power up or during an optics scan.

Solution:
PROBABLE CAUSES:
1. Damaged L1 (projection lamp) lamp cord. Refer to 4345/4355 Technical Bulletin #11. Check for continuity between CN380-1 and CN380-6 on DCPS2. The lamp cord may become damaged if the wire clamp is not at a 90 angle in relation to the wire. The distance between the clamp and CN384 should be less than 5mm.
Replace the lamp cord with (p/n 25BA90163).
Note: Affected s/n range: 45FE02396 through 45FE03851.

2. DCPS2 has failed. The L1 CONT signal is received at CN29-2 on the power supply. The lamp cord, lamp, and F1 are good. The fuser lamps come on at power up, and disconnecting the RADF and sorter from the power supply does not change the symptom. No L1 DRIVE to the lamp. Replace DCPS2 (p/n 45AA84520).

3. CN29 is (mistakenly) plugged into the main CB at CN135. CN29 should be connected to the DCPS2
