Re: Sharp Aquos 80" TV ~ Model # LC-80LE844U ~ Not operational
I'm not sure how to measure this IC chip, but before I had to send it back to the garage for the night I took the following readings of of IC7102:
In this configuration, with the three pins on the top side and the four on the bottom:
1 x 2 3
4 5 6 7
AC Voltage (set to 200 on the DMM) on each pin was as follows:
1 = 12.4
2 = 13.4
3 = 13.4
4 = 13.4
5 = 13.4
6 = 13.4
7 = 13.4
DC Voltage (with the setting on 200m) simply fluctuated quickly and rather wildly between a + 5.0 and a - 5.0. It would change about 4 or 5 times per second, up and down that plus 5 to minus 5 spectrum, back and forth and back and forth on all 7 of the pins.
Does that help in any way? Please let me know if there is a better way to measure the functionality of this chip. Thanks.
