Packard Bell 1015 monitor dead

[Bart Bervoets]

Customer came in with pc with monitor packard bell.
Hit by lightning.
Replaced blown modem and psu in pc, works fine, now
the monitor.
Symptoms, dead.
Fuse was blown.
I checked parts in primary power supply and found no
blown parts, so i replaced the fuse.
Now unit powers up, i can hear HV but no picture.
Led stays on, no suspicious sounds or smell.
Relay does not click, but maybe this model has no picture
on relay or solid state.
The graphic card in the pc was not blown, so i doubd
that the problem is in the rgb input.
Any suggestions?

Bart,

Check the secondary voltages of the power supply, including the CRT heating.
Various CRT grid voltages also should be there.

As for the video, you need a scope to follow an incoming signal from the
input pin to the video amplifier.
