Re: Sony KDL-46EX402 firmware and restarting problem
Nope. Cause a soon as i plug in the AC cord the TV starts by it self. And if i try turning it off (into standby mode) it will turn on by it self again.
That is one of the big problems. I would suggest reading the first post and even maybe the rest. Othervise i haft to go back and copy the whole thing.
But thanks for your time.Comment

Diagnosed this TV as having a failed main board which I've replaced with one from a KDL 55HX850. They are (supposedly) the same board.
Being 'Smart TV' it requires a firmware reboot when you swap out boards such as T-Con or main board. It starts with a black screen and flashing yellow and green LEDS, indicating it needs that firmware boot. The procedure described all over the web is to put the software into the root directory of a FAT32 formatted USB drive and it should load that up once plugged into USB1 port. But not for me. I can see the LED on the USB chip flash for about... -
Hello again everyone,
This is my latest mission, to try getting this Sony tv back to normal working order…
I've only just got it today, when you power it up everything is as should be, in fact it works perfectly for a few minutes then the screen starts getting horizontal lines on & eventually the full screen goes back, I will upload photos of the problem & also some photos of the board etc. You might notice that I'm busy trying the tape method, I'm not sure exactly where the clock lines are so I'm just guessing & hoping for the best lol . I've already tried... -

Hello
Help is much appreciated. I have a Sony XBR-70X850B with bad main board. I got a mainboard for it, but as you know I have to update the firmware on this TV for the main board to work.
I went to the Sony website, and I can't seem to find the Firmware file. Sony is no longer making this available.
Does any of you have firmware / software files for this TV that I can put on USB for update to make this main board work?
Much appreciated. -
I have a strange fault on a Sony amplifier. The volume control varies the display from MIN, then 1 up to 30 and then MAX as expected. At MIN there is no sound. However, at 1 it is quite loud and increasing above 1 does not change the sound level.
I have tried a Cold Reset as per the service manual.
I have looked at the I2C clock and data to volume control chip IC501 (BD3499FV). Data is only sent to IC501 when the volume is set to MIN or 1. At any other setting no data is sent to IC501.
I have looked all the way through the service manual and tried many online...
