Sharp 9" Color TV Model 9H102 AC/DC TV Clicks ON But No tube (snow) or sound

Hello,

My first posting of this may have incorrectly been put in the Introductions so I've copied it to this section since this is a mid 1980s 9" CRT TV. The original posting link is here: http://www.videokarma.org/showthread.php?t=272920

I'm new to this forum and just learning my way around.

I'm the original owner of this Sharp Lyntron 9" Color TV 9H102 AC/DC TV. I have the original user guide, DC plug for running the TV from a car battery 12 V.

I purchased this unit new in about 1984. It ran for many years and then stopped.

I can't remember but I always wondered if it stopped because our house power went out and I seem to vaguely recall that's when it wouldn't turn back on again. But I'm almost certain I had the TV plugged into a Surge protector, so I was skeptical if it was a power surge that caused the problem.

I kept it all these years because I didn't want to get rid of it, thinking I might be able to get it working again some day. At the time I didn't take to a TV repair because I don't think there were any repair shops in my area that even worked tube TV's at that time...

But recently I found out about this forum and thought I should give it a try.

Please let me know if you can help me get it running. I have a very basic knowledge of electricity. I can use a multi-meter and can check voltages. I can also test diodes and transistors and do basic things like continuity checks.

The symptoms are:

The on/off switch clicks on and off with a distinct click, but the TV tube won't come on (light up) (it appears to stay dark, no snow and no sound through the speaker you typically get when you plug in a CRT TV without an antenna hooked up).

Any idea where I can find the service manual for this TV in case someone asks me to check some wiring? I'm wondering if the schematic diagram is inside on the case. Maybe I should carefully take case off to look, not touching the tube, though...
