Hi guys,

I'm looking for a good London based lighting repair person, someone who works at component level on pcb's really. I am happy working on the wiring, looms, switches, motors and most internal moving parts but my electronic component level knowledge is lacking.

I have a problem with the main PCB on a Martin MAC250+ and am looking for someone competent to take on the job :) I have been recommended http://www.lightserve.co.uk/ but they didn't get back to me yet.

Cheers

There seem to be plenty of spares on eBay atm, might be cheaper than repair? There was a main PCB on there the other day for £40, and a display one for £35.

Where was the Main PCB for £40, i've been searching every day and haven't seen a MAC250 main pcb yet!

Only one i've seen is this:

http://cgi.ebay.co.uk/Martin-Mac-250-250-300-CPU-Untested-Part-code-62000049_W0QQitemZ300315479634

And that's untested!

What's it doing/not doing?
Have you checked the driver chips?

The problem is in the sensor circuit, when I remove the Hall Sensor connector from the main PCB and start the light up, it doesn't pan or tilt, but it starts to rotate the gobo wheel and rotate the gobo's.

2 separate Martin engineers have both told me this is down to the sensor not terminating during the RESET stage of the boot up.

The fact that the gobo's continue spinning when I remove the sensor cable from the PCB shows the fault is on the PCB and not with the actual sensor (magnetic based sensor).

Therefore I need someone who can work on PCB's to check it out for me :)
