Sencore LC102 Continues Beep

[glicos]

I have an LC102 that is previously working perfectly. Stored it and never been use for almost 1 year. But when I turn it ON, there is a continues beep. Readings are all ok, can run short and open test and passing. The beep is very annoying. Any help will be appreciated..

schematics are there

not suppose to beep continously for sure ... unless some bad contacts or humidity

Thanks for the inputs. Yup, I thought it was just an open input fuse. But fuse is ok. Will update this post once i identify the problem
