Is this a crt type? If so
I dont work on crt anymore...its been really
A l9ng time since the last time
Although some idea i can share
Is by trying to check presence of high voltage
From flyback..check for oscillation
From horizontal oscillator
By the way....is the osd is showing?
If so then no need to check for high voltage

this can be anything
if the unit is powering up
you can start floating loads
some other techs starts by unloading the horizontal section
like flyback maybe some shorted sa secondayr ng flyback
or maybe vertical ic, deflection, etc.
i have seen some guide by the thread starter, have you tried following those?

Re: ALL TECHNICIANS Show! Your accomplished job here!....

baka po may makatulong:

I have a line 6 30w spider guitar amp.
may power naman sya but there is no output sound.
All i get is parang pulsating na ugong.

note: walang issues sa guitar, sa cable or sa wiring to speaker.

 

[electrodan]

Re: ALL TECHNICIANS Show! Your accomplished job here!....

tried to do some research online
mukhang wala akong makitang complete schematic
is this a version IV?
Wala akong masyadong experience sa line 6
but most likely na nakita ko sa ibang brand
if using a smps most likely nandun ang sira
like bloated caps, no supply going sa amp.
