Dear all !
Two weeks ago I had the idea to re-invoke my vintage StyleWriter bought 1991.
But after pressing the "power" key none of the LED lights up.
Voltage from the external power supply was present (13.5V).
So I opened the printer and found that at least 4 capacitors
had been leaked (C4, C410, C8 and C9).
During further restoration I found that all electolytic capacitors
(except C2 and C3) leaked and lost its capacity.
The PCB is damaged. Below C10 is a small cavity in the PCB.
Some PCB vias and PCB wires are destroyed.
One pin of transistor D33 was completely etched by the leaked C8.
I'm not sure if the PCB can be restored.
Can anybody provide the schematic of the board ?
Knows anybody the type of the transistors D31, D32 and D33 marked "M.C." ? | Posted by: RV066 on 2023-06-23 09:25:24
I forgot to upload some pictures of the logic board | | 1 |
