Hi ALL,
I have a weird problem 3 PVRs have the same issue after a power cut, before this happened all 3 been working fine for years. After home mains power was restored HDMI no longer works and will produce the same error on Screen - N0 Signal. All TV has been tested with other devices and HDMI work fine.
All 3 are genuine and out of warranty, models are SOLO 2 X 2 and 1 ZERO.
The Solo2 works fine on Scart.
A fresh image did not fix the problem.
I have checked the inside these have never been repaired however they came to me to be fixed.
The HDMI port under the microscope looks brand new.
From openwebif I can see that all 3 are working fine.
Before I attempt anything I would like your suggestion on why this may have happened and what steps I should take, settings re HDMI in PVR are FINE.
I am an electronics engineer with 20 + years of experience and have never seen anything like this before, does anyone have a schematic for these models or a link where I can match resistance value and diodes in circuits, please? I have tested for short to ground however found nothing so far.
Any help & ideas are welcome thanks.
