I'll try to give the readers digest version of the question so I do not put anyone to sleep...

I was given a big screen tv, a really nice one about three months ago and it worked without fault until I tried to move it downstairs in my apartment. Once in it's new home in my living room it worked for about 3 hours, flickered, then went out. I herd a high pitch sound and smelled something like a component overheating. I use to work on electrical components about 10 years ago and am picking this up as a hobby again. I have voltage testers bench style and signal generators still but my Oscilloscope didn't make it through hurricane katrina. If I'm going to be working on this TV or really any other tv and so fourth, what frequency range that I need? I would hate to purchase one that goes up to 75mHz when I need one that goes up to 80mHz

the mfg website might have some info.

It's been years since I even thought about TV's, but I bet that the all the RF stuff these days is inside a $20 module that you would replace anyway. Something capable of probing video ought to suffice.

Maybe the first thing is to see if a schematic or shop manual for the TV is available.

The TV is a 1996 model so I'm lucky in that sense.. It's a Zenith rear projection and all of the boards are not stamped but workable. All of the resistors cap's and transistors are solderable and removable... It's a big mess of boards and wires and alot of high voltage... The schematics are almost impossible to find. I have email zenith and no go, and have even tried on alot of other forums... I figured it would be a hunt and peck job for me but something to tinker with...

Thanks everyone for the responses... Wish me luck!!!!

If you get a 100mhz dual trace scope, it'll do anything you'd need to do on a TV repair, or most other common household electronics. There are good deals on used equipment to be had in many places if you can't justify the price for a new piece of equipment.
