Hi All
Thanks for the reply people
Apology again can someone please point / link to me which unit [TFT colour kit] that was mentioned? I',m happy to build it and add this to my arsenal of tools to figure out this GPU issue however its impossible to obtain the schematic, but I suspect something is causing the GPU not to post to display, I could try the "other" myth of baking it but for now happy to try my hand in trying to check a few caps /trans etc see if this leads me to the defect. If it ends up being the GPU MPU itself so being it.
I was going to try and build the CRO method of adding in a 100khz signal but my freq gen is somewhere in storage and hasn't been used in like 20 years! I'm trying to get back into some basic fault finding and hope I can have a crack and resurrecting this paper weight
A link to the latest Kit and FW I should grab from ebay or another source would be appreciated chaps,
PEACE
Kosti
