Sorry, no. If a boot loot should be a mainboard in the theory, but, I've proven myself that not always. Try to disconnect backlight error pin on the backlight PCB if firmware upgrade won't work. Not always a customer is right. 😉

Thank you, will try :).

Thank you, but, I'd rather do a Frankenstein out of it if can find VGH, VGL, AVDD & VDD signals for this particular display ;). Can be a Panasonic or Samsung after, I don't care :D.

@@screen-protector lol

@@wisher21uk Not always I can do it, you know. But, if I can find all the signals from the T-con = why not ;).

Got the link please

Well, after trying a USB stick and no success with the update, I've decided to buy a 2nd mainboard which failed. I did not check any forum, if Polish you meant Elektroda by any chance? I try to cut the time of fix. That's why when possible I prefer to buy a board than fix those more complicated ones and waste my and the customer's time. I'm trying to keep my 5-star rating on Google :D. And, when having a good board, I can compare readings of voltages and even with an oscilloscope if have time to do so. I'd love to have tonnes of time to spend enough on those repairs, but, my turnover is too big to afford it ATM.

@@screen-protector yes I did; seems to occur after the last software update - seems downgrading it and disabling ota update seems to fix it for now

@@cheapasstech you were lucky then, that's nice :).

@@screen-protector have a Sony KD-49X8309C in that does exactly the same thing …

Do a Frankenstein ;) then. Why not?

@@screen-protector worth a try

How to put the firmware on the chip then tho or will the tv even do the install with a blank emmc?

@@seesikopter you need to buy a chip with firmware on it, BUT!! Some of the apps won’t work like Netflix

@@wisher21uk that’s not an issue to me, I just want my new broken tv working (I bought it as „for parts“ to repair but I had higher hopes than I seemingly knew what to do to repair)
