PLED module problem
2003-10-17 by roelp23
Hi, I've just installed the new PLED module, and at first sight all seemed to work exept for the PLED module. After turning the 'brightness' trimpot the opposite side the characters showed up. I found that a little strange because I had to turn the trimpot to the opposite side then with the LCD module. But what the hack, the display looked great. But after 5 min the P3 suddenly stopped operating, like the power went off. But it didn't. I tried to restart it, and it did but now the P3 broke off after the firmwarecheck. I got nervous and opened the machine again, and then got really frightened for there was a smell of burning electronics inside my machine. After some researche I found out that r19, the 10R resistor next to the trimpot, was burned out. So I soldered a new one in place, resarted the machine, and all seemed to work again. But I felt the resistor and it became really hot, and after some time the P3 stopped again. I checked the wiring, the PLED module (a PDC1602M), but I didn't see anything strange. I have a 10R resistor from lead 2 to point 2 on the module, and a 10uF cap between point 1 and 2(-to1) I hope someone got a suggestion, or that I did some little stupid thing, cause it looked great and I can't wait to play again!!!! Cheers, Roel
