I have a cheapy 19" Philips TV hanging on my office wall.
It's taken to making a popping noise, suspiciously sounding like a
spark gap.
I'm pretty sure this is CFL back-lit.
Anyone knowledgeable of what to do about this... adjustment to look
for, etc ?
Update: While on a phone call I noted that the muted TV has no pop,
and the screen never did "blink", so the popping noise must have
another cause.
