Hello,
First off my apologies, I'm in the USA and I only speak English.
A long time ago I bought a BK-0010 and a Vector-06c off of Ebay. The BK-0010 works fine but the Vector has lots of problems. I've already replaced the CPU and two flipflop chips so at least it boots, but now I'm stuck.
As you can see the colors are very washed out. I followed svofski's modifications to get a good sync signal, but when I tried to wire resistors R16-R29 directly to the inverter I only get a white screen. So I reverted it.
When I turn on the computer I hear a buzzing noise, the "rus" LED is on, and I see this checker pattern on the screen. When I hit "vvod" and "blk" the screen goes blank, the LED turns off, and the buzzing stops. I also hear a "click" noise.
I hooked the cassette port up to my PC and played back a wav file. I can hear it on the Vector-06c's speaker but nothing else happens.
I'm not sure what to check next. I think the computer is running but it won't load a program and I can't get a good picture out of it. Any help would be greatly appreciated. Thank you!
