Falcon - NO VIDEO SIGNAL

Post by marss »

Hi,
The Falcon is powered (LED shines, Fan of the CT060 turning, HDD working) but NO VIDEO SIGNAL ;(
What could be wrong?
Please help.

What happens if you push the reset button?

You really should do some troubleshooting yourself before asking on the forum. The first thing is a no brainer, remove the ct60 and any add on cards then try.

Tried RGB & scart ? was it ever working ?

Mostly machines end up coming to me for repair when this happens otherwise, either blown 12V line somewhere, or blown videl/codec chip.

Tried RGB and SCART... no luck
Could it be that the orange thread from the PSU touching the inside of one of the white plastic connection be the cause? if so, what could be the consequence. If still problem, so Exxos will be happy to repair it ;)

Check your PSU has 12V output.. you should also check you have 12V power to the video DAC chip. I have seen a lot of power issues on a lot of falcons.. seems like tracks burn out :roll: I've seen a lot of blown videl's in Falcons over the past 2 years, I can't really prove it yet, but I think its bad PSU's blowing the chip up. Its why I suggest people re-cap their PSU's and don't use picos.

Posible I could repair it, but I send off to another company to change chips now, I'm to old for all that stuff.. but I have that much repair work to get though and no time to do it all.. probably be next year before I can catch up.

I must ask:

Why to not use Pico PSU?!


@marss
If you have black screen maybe RAM is problem.
