Hi D, At the risk of sounding patronising (not intended, honest) have you eliminated all the other possibilities? - Was the Iici working before it was recapped? - If yes, were there any particular symptoms such as odd images on screen? Checkerboard? vertical lines? - Have you checked there are no dry solder joints? Magnifying glass is good (personal experience) - Check ALL joints, not just the ones you did. - Have you checked there are no bridged solder joints? Again magnifying glass is good (personal experience) - Are the brightness and contrast controls turned up on the monitor? (I swear this is a thing, personal experience) - Are you getting all the correct voltages from the PSU rails? - When you recapped the mainboard, did you recap the power supply as well? I do this as a matter of course. All those heat up cool down cycles will eventually throw the voltages off. - After recapping the mainboard, the board was cleaned to remove any residue of battery and old cap electrolyte? Electrolyte will causes shorts. I use isopropanol/isopropyl alcohol but I have run a dishwasher cycle or six on Analog/PSU boards as well as mainboards (remove chips from sockets before washing). - Can you check the monitor works with something else? I know it sounds like I'm covering the obvious but it's all meant in good faith. Cheers, Keith

The boots with a normal chime and the 13” RBG monitor powers up, although the display remains blank. The PRAM battery is new as well. I have read through some posts on similar problems and I’m looking for suggestions on isolating the problem; could this be a problem with the onboard video or has the monitor finally died? -- -- ----- You received this message because you are a member of the Vintage Macs group.
