Hitachi 50HYT62U/Vestel Turd

[synaesthesia]

Have picked up a 50" Hitachi/Vestel thingy recently with a screen that turns on grey then fades out to black. Backlight appears to be working and PSU is OK (had a spare, both with the same result).

Looks like a firmware issue after a little googling around. Would anyone happen to have the firmware for it? The board is a 17MB95M with sticker 10090755 23193499

Failing that, is there anything else I should be looking for on this?

Cheers

i have just dumped the same tv, but it was PANASONIC/VESTEL, i had the same problem as you, all turns on ok, with back lights working, and it turns out i had a shorted screen tab, so check the fuse on the T-CON first, and if that ok, check the screen tabs for heat,

Cheers. Unfortunately now too late Managed to drop the bloody panel
All is not lost though, the LED's were mostly good and I'll be using them as lights in my new mancave

It's my first I usually work on my snooker table however I'm currently clearing out my shed, so my work area is significantly reduced. People call me intelligent, but I often doubt that when I'm resting a 50" panel on a small box and then go to pick it up by each end.
What a plum! Lesson learned!

Lol you wont do it again, Im a jammy bugger as sometimes I do get rough handed but not had one crack yet.. But I did have a 60" Samsung Plasma which was a customers repair job that cracked on me due to a panel short if you want to find out why I can link the video on the repair I did cry over that I tell you

no backlight showing voltages seem ok on psu
backlight legend connection + 156 volts steady - connection 36 volts but fluctuating from 36 volts to 37 volts im suspecting bad LED
