Son's Sony TV dead KV24fv300...

[john smith]

My son's KV24fv300 is 2-3 years old, but the picture has suddenly failed to
come on (black screen). The audio, remote, etc. is normal. I can hear a
relay click on, then another that then perhaps seems to open.

An led on the front blinks several times then stops.

No smoke or smell.

Opened the back, but unsure where to discharge the coating on the screen,
etc., whether necessary to try to d/c the high voltage (red line to tube
from flyback) after many days of no power connex. Built discharge devices
to do it safely, but need instrux or diagram.

Located info indicating similar symptoms repaired by replacement of an open
resistor and an adjacent killed ic, but I'm afraid to grab board and pull it
out without discharging caps, hv, tube etc. Not sure what holds board
in...appears to just
slide from slot (no metal chassis whatever).

I could really use some advice- if this IS the problem, repair will be
simple, but I need some discharge advice/diagram
info before charging in. I am not capable of or interested in working on a
live chassis.

Thank you.

Reply with the blink sequence from the front led. Other posters can
interrupt what this may mean as a basic diagnostic. Really, however, if you
do not have experience servicing SONY products you may be much further ahead
in contacting a SONY authorized service centre.
