So my cheap/free HF voltmeter was working fine until last night. Today, I turned it on and display is all wonky and very dim, thought it's a battery. Tried 2 different new batteries, but no luck. Has anyone experienced anything similar? Yes, I can get a new one for free and do have a spare one too. But I rather not trash it if it'll work after a battery or some other minor fix. Thanks for the advice and help.
