Re: Half success on AL1716
From Power board is 5V, this 4V I send From other power supply. I tested 5V down regulated and all other supply for chip measurement. On 4V is Display aktivation on ACER Logo. Processor and EEPROM is OK.
If is Connected Power Board and Logic Board, LED Power still flashes green/red (1sec).
On 2 PIN +5V is 5,01Volts
On ON/OFF and Brightness PIN I cann not measurement.
Backlight have tested separated Power Board, 5V on ON/OFF PIN....Leave a comment:

Re: Half success on AL1716
Hi, sorry for my english.
I have the same Al1716 on "severach" Photos. P/N ET.1716P.014
I have Problem with TSU16AK. My chip U101 AS1117L-18 have only 1,2V.
If is Power not 5V, but only 4V is Logic OK. The Acer logo shows clear, unfortunately the VGA input is out of sync.
If Power is 5V, that LED Power still flashes green/red.
I need Schematics, but Elekrotrotanya have only other Models.
Can you help me?Leave a comment:
