You are still lucky
@Optimus_Prime bro. My Videocon 42 iinch DDB LED TV developed issue in motherboard / PCB, i registered request for replacement of motherboard back in Feb 2021 and 2 days later even part request was approved . Then came the sad part, part was unavailable and i kept continuosly following up directly with videocon, their service center and made hundreds of phone calls /sent around 50 mails ..... Kept waiting n waiting. First due to corona lockdown all things were shutdown then part was unavailable as videocon was reportedly being acquired by Vedanta at that point but it did not happen hence factory remained shut and later i requested service centre head to arrange the part from open market which also resulted in no solution. Even registered complaint with Urban Company, technician came and told that this part is not available.
At present using the faulty TV, it does switch on but backlight from 3 corners r not lit properly. Fortunately bcoz of the kind of person i am, instead of giving i tried to find a way by which this issue can b resolved. So i understood that PCB is unable to deliver required power to the Panel Board and hence reduced backlight to 0 then toggled between modes and switched on and off to see if TV starts working properly in either modes/source. It did not yield any positive results so then i tried out combinations of switching off/on and toggling between sources and finally i found the right combination. Now i switch on the tv, select AV1 mode then go to TV/RF mode, switch the tv off from remote then switch it on and then go to AV1 mode and switch off/on the tv and finally backlight issue gets resolved and then i select HDMI mode to watch channels. All modes except HDMI have backlight set to 0 as this solution only works if same is done. Even TV speakers not working hence connected external speakers directly to AV out port on the stb
