    Sony 40S20LI Success Story

    Ironically enough, no question here.

    Just wanted to pass on a success story..

    Got in a Sony 40S20LI. When powered up, there was a high-pitched whine. There was a picture (analog snow) but the upper half of the screen was darker.. After a few seconds, the system would shut off...

    Figured it was the side boards (buffers??) that were shorted or bad. I pulled off the "blast shield" to see if I could see where the problem was...

    Lo and behold, the TV powered up and worked fine..

    So, I can only assume that the shield was shorting the upper board in some manner..

    Just passing it on, since I see a LOT of comment threads regarding Sonys...

          I had a sony a while back that the backlight board was arcing to the chassis because that 'blast-shield' was a little bent somehow.

          Bent it back out and made sure the board had some clearance to the chassis, the set was fine then....

                              Whirlpool PACF212HP W portable air conditioner, upper fan only turns slowly.
                              by spleenharvester
                              I just acquired this portable aircon, history unknown. Its behaviour is quite strange:
                              • When turned on and placed into cooling mode, the upper fan (cold air out) just spins slowly. The compressor and lower fan do not run.
                              • If the device is then placed into heating mode and then back into cooling mode, the lower fan and compressor kick in and start cooling, but the upper fan still only spins slowly.
                              • If the device is placed into fan-only mode, the upper fan does not respond to low/medium/high speed toggles - just keeps running slowly.
                              • Display and buttons all behave normally aside from the
                              ...

                              Sony KDL-46HX850 Can't upgrade/update firmware
                              by dkneyle
                              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...
