    Finlux 32FLD760P Sound and backlighting but no picture

    Hello, I hope that one of you talented and knowledgeable guys or girls could help me.

    My telly screen suddenly went blank last night. The video source and HDMI inputs can still be selected as I can still hear the audio from each input and the LCD backlight is working. I cannot get any picture or screen prompts/graphics.

    I have trawled through the other two Finlux 32FLD760P threads in this forum and can confirm that all power supply rails are at their correct voltages and are stable. I've checked all connectors are secure and have done a search on all PWBs for any cold or dry joints.

    Any help or suggestions would be greatly appreciated.

    my guess is the fuse on the t con board can u supply pictures of the boards in your set? some/most times the t con is under a metal cover.

        Hi again. Please see the module pictures below.
        I assume the fuses on the T - Con board are F1 and F2 SMDs. I believe F1 is open circuit. Do you know the part number or rating?

            It has a P on it which is a stated in the post you provided the link to.
            Many thanks. I'll let you know if it's successful when I get the part and fit it.

                While I'm waiting for delivery of fuses I bridged the blown one with a 3A canister fuse and hey presto everything works. I'm leaving it soak testing now
                Thanks again

                  i use a 12 volt car fuse the plastic type with soldered wires on if it does blow maybe its a shorted smd capacitor can be hard to find the faulty one imo the price of t cons i just exchange them.

                    It's been running 4 1/2 hours now and no problems. Yes, I see you can get t cons for under a £10. The fuses were only £2 for ten but if it fails again I'll get a replacement t con
