it's weird . technicians are kinda like doctors . they should be good at diagnosing the problems , so try to approach more than one technician
@NeedToKnow .
I once had problem with my washing machine , one guy said it was motor problem and need to be replaced (6k estimated cost) when he replaced it , it didnt work .. got the money returned . But then another guy came out and said it was a sensor issue , replaced , worked .
my vendor never charged for any repairs of my personal systems as he was earning lot more from my referrals as he provided excellent service. actually the monitor was pretty old, repaired twice but as it was working, i didn't upgrade to a LCD / led one though asked about various models, once even brought a 24 inch dell but immediately returned as it was a different model. the CRT was used extensively for almost 10 years and i too was fed up. the person / employee who used to do the repairing said this after second repair though he was scolded by the owner when he came to know. thanks.
in 1991, head light of my kinetic honda was extremely dim for which the engineer from the factory asked me to get the magnet replaced which used to cost around rs.800. i said do it but refund me if it doesn't work even after this. he said sir we need to check after changing it. i said my condition remains the same. he slowly walked inside on the pretext of talking to someone.
later a mechanic tied two wires from battery and frame and it started shining like anything. no money charged for it.
