Hello,
I'm new here. Maybe someone would help me. I have Robotron A5120 which cann't turn on by front green switch or by the green one on keyboard. No reaction at power plug.

Open the computer.
Are two red LEDs shining in the basement below the CRT?

 First of all: check the fuses spread all over the computer. In almost all cases the fuse holders are heavily corroded. There are some at the pc-boards in the "foot" of the A5120, some in the power supply units at the back. To get to the boards in the foot, You have to disassemble the whole computer. But this is anyway a good idea, because there is always a lot of collected dust to remove.

Thank you for your answers.

@Rudiger
Will check that but after removing some parts of case and looked inside I have not seen anything that might work (no lights and no "working sound").

@TTL-Grab
Yes you are right. First I have to check all fuses on boards. Disassembling is not complicated because I have experience in PC repairs and here this item was assembled in some kind of scheme but from first look it will take me a half of day

I have very small room and have to get rid of many things to get space for work with Robotron.

Will be back soon. Thanks a lot for quick response.

Search for two lonely fuses (the primary fuses of the computer) in the basement.
Therefore you must remove a side blank from the basement.
You need to release two screws. Only release, but do not remove the screws completely.
Measure these fuses. Result?
