Picked up the ampro today. Turned it on.
Remote shows: sssssssssssssssssstrss
Device clicks.
Errors appear.
Device never turns on.
What causes this?
These are the errors

Error 08 at 5a
Error 08 at 56
Error 08 at 44
Error 08 at 4a
Error 08 at 72

It's a lot of them, opened up device no dust everything looks brand spanking new. Is it time to scrap it?

Opened the device at the power supply the - 20v doesn't light up.
I hear the cathode ray tube firing then it shuts down and kills power to the psu

There is a Lithium battery somewhere on the CPU board, you should check that how is holding up. I am not an ampro expert, but I seem to remember a weak battery can cause all kinds of problem, maybe a good point to start.

The f2 fuse is blown, hafta replace it first.
Where's the lithium located? I'll measure it, should be 3,7v rite?

Battery is on the CPU board. Black rectangle looking device.

Put in a lesser fuse, blows.
Put in slightly heavier fuse, magic smoke comes out of rgb cart....
I think I have a short there..
Can't see it by eye.
Still the same error, I've reseated every connection possible.
I hear the tubes firing up, but it shuts off.
What to do.? Magic smoke came from right side of cart, where there's an ic labeled c64 and where there are three transistors.

Error 08 at 56 is the first error

With the - 20 volt fuse blown, you'll get error codes, as I believe it sends voltage to the convergence board. If the RGB board has smoked, that's where your problem is. Give me the 5 digit board number and any revision after it.

Also, take out the RGB board, put a new fuse in, and turn the projector on. See if the fuse still blows.

I've got those boards in stock for cheap.

Took board out fuse doesn't blow, system says open interlock though. Nothing happens.

Battery on cpu board dead as well, is this thing salvageable?
The tubes are new, in fact the whole thing is brand new inside
A waste if it's not working

On the CPU board there are a row of switches. The 4th switch is to turn on the interlock detect. Flip it and try to start again.

Device reads memory failure. Because battery is dead.
However, I can turn it on, tubes get power but no fans run and smoke came from these two locations.
It does not smell burnt, it's different.

Makes me wonder if it was more then a demo for the importer, like a parts mule. I've had them before.

Fuse f5 also blew

I'm removing mains power now and stop trying until someone has any idea. I don't feel like setting the house on fire

Let's make it less confusing.
I switched dip 4 on cpu card to down position.
Removed rgb card.
Power up.
Remote says memory failure.
No fans run, tubes get power.
Red light on back of psu does not light up.
-20 light stays off.
Tubes don't light.
Because fans don't run, psu overheats system shuts off.
System turns back on again, the +40 fuse blows.
System gives rgb channel 1 error
System gives 8 at 54 error.
