Re: Eprom dump versus firmware update

Firmware updates are different from the content on the 25Q32. It wouldnt work if you put the firmware directly on a 25Q32 or vice versa.

Re: UN65NU6900F - Backlight No Picture

Re: UN65NU6900F - Backlight No Picture

Remove all those diodes. As far as I remember those are for protection purposes. You can either replace them or leave the board without diodes.

Re: Sony KV-XJ29M31 CRT TV - Very dim image on turn on

Does the led flash 5 times when you turn it on? If so the crt screen might be dying. In my experience sony crt tvs had only 2 major faults: crt and flyback transformer.
