Stap 5
With selected FAN I used the TV's  original heatsink again. FAN housing fits flawlessly over the heatsink and inside the TV's rear housing. First trials I did with tape(photo), later I glued the FAN housing with hot glue to the mainboard. without rear housing temperature on heat sink surface dropped down to incredible 29degC (ambient temperature 21degC), however, with rear housing it rose up again to about 44 degC. First I thought about drilling additional holes in the housing, but finally I decided just to remove the lateral and bottom output interface covers of the rear housing.  This might be  ok for you as well, as these covers are distal to the HOT area, so there is no risk of direct contact to high voltage. This way I now get 39 degC after several hours

  • Margin to shut-off temperature is about 10 deg., so I probably need ambient temperature of 30 degC until I will run into trouble again. That seems to be ok for me for now., 30degC in my room would be pretty tough, but let's wait for next summer...

  • Be aware, removing lateral covers from rear housing might not be dangerous for direct contact but violates any standards to prevent you from inserting any metal object. So if you have a kid that could even think about, better keep the covers and accept the higher temperature and smaller margin.

  • Or add small holes in the cover, where no one can insert objects. .

  • Additionally, without the covers you have to be more careful, not to damage the interfaces mechanically when inserting USB stick, antenna cable, etc.
