BUSH LED40127FHDCNTD - HDMI Inputs Malfunctioning

[Dakno]

Hello,

I have a BUSH (Vestel) LED40127FHDCNTD TV with mainboard 17MB95S-1, about a month ago the TV had issues with a flickering backlight on any brightness setting except the highest, i just kept it at the highest from that point.

For the past couple days however this is completely fine, but HDMI inputs only show black screens (If they sense an input at all). All other services such as netflix and iplayer are fine, and the controller works at all points, however i am yet to try the VGA input or any other (Dont have any at hand right now, will edit later if i find something)

I have tried factory resetting the TV, but have not been able to find any software/firmware online to try reinstalling or downgrading.

I will post pictures of the mainboard and PSU.
Any ideas?

Thanks!

Sorry for bump, cant find the edit post button?

I've found a few replacement boards just in case nothing can be done for the TV, however they do not have the same serial on the Bar code (Mine is 23164325) other then one £70 or so one... My question is wether they would theoretically work still? And if the board was for less than 40 inch and less than 1080p, would it still function fully?

Hi there,
vestel boards are notorious for matching up with the panel,(screen) and even the power supply.for example,there are around seven different versions of any psu,and,comfusingly,they all have the same part number,example 17ips19..Possibly a firmware glitch you have,but as you have found,support is non existent in realiity..also the service menu may as well not exist-nothing can be changed on it..Probably the only road to go down is replacement.The barcode number is ever-important,for pcb replacement.Grab a cheap smashed screen one from ebay would be my choice!...Tom66 may chime in with a different solution however.Good luck!

Yeah im mainly just searching for either broken tv's or maybe someone selling spares for the board but no luck so far... I did manage to find an update file for TV's with mostly the same board and tried to install it, however i think it may have lacked the Power button my TV had and can now not turn it on! The controller also doesnt respond, is it possible for the software to change the Remote code it responds to?

yes you are correct, if you look in the service mode there is more than one type of remote control code used but in the service menu these are read only and cant be user changed, some makers such as sharp and toshiba use there own remote control code, I have worked on a set which came with a toshiba remote and after I played about with the software would now only work with a vestel remote.
