Hi
I have a Samsung QE55Q65B with a seemingly common problem: it turn off and back on after a few seconds, (sometimes more, and in rare instances works for hours). D001 on the left side of the panel is very hot. I may be able to remove it with a very fine iron, but i don't have the equipment to re-solder such small parts.
Is there a risk to run the tv without this diodes diodes? And is it worth to pay someone else to replace it. I read many people who ended up with bad lines after trying to remove/replace them, , or the panel failing in another way, so i want to weight...

Re: Sony KDL60w685a need firmware update
Sorry for the late answer, i hadn't much time to take care of this. The firmware worked fine, another TV saved from the landfill -
Re: Sony KDL60w685a need firmware update
Thank you. The mainboard in my tv was dead, so, i bought one on ebay. It now gives me a red and yellow light, from what i understand it needs to have the firmware updated to recognize the panel.
Ps: i can't edit the first post, maybe a moderator can fix the model number, in case someone needs this firmwareLast edited by madyoyo; 01-06-2023, 04:29 PM.Leave a comment:

Sony KDL60w685a need firmware update
Hello everyone.
I replaced the mainboard on a KDL60w685a, and now it blinks green and yellow. I think i need to update the firmware. But it's not available from Sony website.
Does anyone have the firmware for this TV? -

Samsung UE43J5500: Replacing main board by another model or screen size
Hi everybody;
The main board (bn94-09121q) on my UE43J5500 is dead. I can't find the exact same board for a reasonable price, but some other part numbers are pretty cheap, they are physically identical, and based on the bn41-0235 board
Can i swap the bn94-09121q by another "letter", like a bn94-09121N, or even from anoter screen size? -
Re: Samsung UE43J5500 No red light despite PSU testing good
i've found a schematics for this main board: [url]https://www.electronica-pt.com/esquema/func-fileinfo/82533/[/url]
Everything is done inside the microcontroller, so it's basically dead
Its more than likely it was killed by a power surge, being powered on all the timeRe: Samsung UE43J5500 No red light d...ything is doneLeave a comment:

Samsung UE43J5500 No red light despite PSU testing good
Hi everybody.
I have a Samsung UE43J5500 with a bad main board: No red light, and zero reaction from the remote or the power button. The PSU seems ok: 8.6V when plugged in, 12V and the backlight turning on when disconnected from main board. I also found 3.3v at the ir receiver, the power button also seems ok (i get 1.8v at the key_input1 test point, and it drops to zero when the button is pressed.
Is there anything i can try before tossing this board? I'm running out of ideas -
