Re: eax64905001 No Pfc Help ?

One more thing is after cca 10minutes of measuring is hard to touch heatsink on Q101 because of temp I think about 60°C.

Re: eax64905001 No Pfc Help ?

Please for advice. Voltage on P801 - led output is between 0 - 0.6V (oscilating). TV is operating (with headlamp directed on LCD panel I can see MENU). Testpoints P802 (43-45V), P803 same. P203 11.9V, P202 23.3V, P204 23.3V
Q801 - DRAIN 44V source and gate 0V
Q802 - DRAIN 0.130V source and gate 0.020V
Main voltages are 3.45V, 23.4V, 12V, on con. to Mainboard PDIN 1.12V and DRVON is 3,0V
On IC801 pin 9 PWMO (to Q802) is 0,02V. Vcc is 12V and REF is 4,96V. But gate pin 3 is only 0,02V. Thank you for any advice. What voltage...

Thank you, I'll do some measurements.

Hi, I have similiar problem with EAX64905001. I have no output voltage on con P801 with unconnected LED panel. Is there any protective when there's not load on output ? Or should be there 80V ? Thank you.
