Hello Circuitbenders Uk
I’m sitting with a Peavey PC1600, which has some LCD issue and I’m actually not sure how I should manage to fix this problem.
• There is not much help to get by Peavey as company.
The former owner sold the unit as “defect”. He tried to replace the old LCD with a new LCD and ran into a problem. The LCD is flashing but only showing some “Black” squares on the top part of the LCD.
I have tried taken some pictures:
1. The unit

6. LCD backside

Any tips? Tricks? Hints?
I would greatly appreciate any kind of help! ;)

not sure if this will help or not...
i have a kenton control freak which was doing the same thing
it turned out for mine that the power supply brick was faulty...
i would try another power supply if you've not already and see if that makes any difference
mine also had bulging caps at the power input socket which i replaced, although that didnt make any difference to the lcd

i hadn't noticed this thread when it was posted, or i would have pointed out that the backup battery is missing from your board.
My PC1600 wouldn't start up properly with a dead backup battery, but i don't recall any blocks on the screen.
