Worth buying faulty Hantek DSO5202B?

[szevlin]

Is it worth buying a Hantek DSO5202B scope as faulty or is there little to no hope in fixing these?
The seller says that the scope displays a trace but the trace doesn't change when a signal is connected. (like as if it was always coupled to ground when its not)
Thanks

That's up to you....  and depends on how much money you are willing to loose.

My personal experience has been that modern cheap crap like this is generally not repairable or not worth repairing, unlike older gear that you can at least get a schematic for.

Also, I find that with the asking prices on used, often ancient and clapped out test gear, it may actually be cheaper and better to buy a NEW piece that has a warranty and is IN SPEC.

It's fun to repair old Hewlett Packard, Tektronix, etc.  But Stuff Like already cheap Hantek, etc....

Really depends.  For under $100 I MIGHT try it.... but only because I can afford to loose $100.  Not really, but it won't kill me if it's junk.

A few years ago Hantek DSO5xxxB scopes have been reverse engineered by people on this forum, at least HW revisions up to 1007.
One crazy even upgraded the analog frontend to 300MHz.

Download the schematic and decide if you feel like messing with it. The analog frontend is right on the first page.

How much are they asking for it? If the price is right I would buy it given the opportunity, anything like this is a gamble but overall I've done very well in the casino of broken electronics. YMMV.

my bet is on "no"
but if you like challenge and you can use another scope to diagnose the dead one, it's your call
