Re: This guy has an RCA 42PA30RQ

OK, you can use that but I recommend a fixed 10X probe. If you switch it to 1X you risk damaging the scope.
I use my 1102E to test plasmas too.

Re: This guy has an RCA 42PA30RQ

I have a good set of probes with 1x ref and 10x. way better than stock that came with my scope...It locks in the 10x setting

Re: This guy has an RCA 42PA30RQ

I don't have an Isolation transformer, can it be done without that???

Re: This guy has an RCA 42PA30RQ

On the Y-main and X-main, yes, they are isolated from the mains power.

Re: This guy has an RCA 42PA30RQ

Re: This guy has an RCA 42PA30RQ

Scope:
- CH1 ON, CH2 OFF
- DC coupled
- BW limit ON
- 10X probe
- 100V/div
- 10ms/div
- Acquire mode: Long Mem
- Set trigger to a few volts above VSCAN (will be indicated on PDP)

Probe:
- Set to 10X. Do not set to 1X.
- Probe topmost lead of C5035 on Y-main. It's a poly film cap near the outputs to the buffers. Topmost as installed in TV.

Use the Rigol's screenshot feature and upload a pic of what you see when TV is powered on.

here are soem pics... the fuse on the PSU on the lower left side on primary side is the fuse that doesn't have any voltage reading
