Hello,
I was given a 19" Jensen JE1907DC TV. It came out of an RV and is powered by a 12v DC power brick.
When you press the power button the standby light goes from red to blue and the Jensen logo shows on the screen for a couple seconds then the TV turns back off and the standby light goes back to red.
The last pic shows the connectors where I measured voltages.
The readings I got @ the connector in the top left in standby and power on are
12v 12.2 - 12.2
12v 12.2 - 12.2
PWM 0 - 2.9
ON 0 3.2
GND
@ the connector at the bottom of the pic
NC 0 - 0
NC 0 - 0
CN2 1 - 0
PWM 0 - 3.2 (when pwr button first pressed) - 3.6 (when jensen logo is shown)
ON 0 - 2.9
GND
GND
12v 12.2 - 12.1
12v 12.2 - 12.1
GND
3.3v 3.3 - 3.3
GND
5v 0 - 4.8
GND
Unless I am missing something those voltages seem about right..what do you all think?
I don't see any obvious signs of any bulging or leaking caps on any of the boards.
thanks for any help
