Hi,

I fixed a 53h71 with a new stk 392-150. All works fine but now the tv turn off and on by itself. I found a service bulletin for the same problem but it's for a 50hx70 model... I must add a 47uF from QA01 pin 54 to gnd. Is it the same fix for a 53h71 ? Any idea ?

Thanks

Yanmar

Solder the jumpers on the signal board. IE the ones around L7711. Try that first.
