My brother gave me this oscilloscope.I not sure if it will work for testing on tvs such as for bad tcon board or panel.I know it is 20mhz.It is not in best physical condition but looks like it works.

A tad rough but it looks mostly complete sans a knob.

Based on the age and looks like not too ideal storage conditions before you might have to pop it open and give the front switches a cleaning with your favorite electronics cleaner (I have deoxit myself).

If the line jumps around when you bump switches it's almost always dirty switches, or if it's unstable at certain switch positions.

Will 20mhz be enough for tv repair.

OK for Checking switching power supply, audio, but the LVDS signal can be >100 Mhz.

I've heard good things about the Rigol units if you want new.

If you look used it's easier to just look around to see what there actually is then go based on what you find. Looking on what I assume is your local craigslist (Dallas, TX) I don't see a whole lot but something might turn up.

Why don' t you clean up the switches and controls and then use it just to get use to how to use the scope before spending more money, it will more than good enough for troubleshooting power supplies.
