hey friends need your help in this issue, i am new to this forum and i don have any knowledge in servicing electronic componets.
1. acer x193hq monitor is not working, after powering on it shows acer logo and then displays no signal msg with power light turns amber from blue.
sometimes is shows cable not conneted with blue power light.
2. i jus tried to tap on the backside of the monitor , display working sometimes. so i thought there may be a chance of loose wires or bad solder joints.
things tried so far-
totally disassembled the monitor and checked for blown capacitors visually on the main board , power board everything seems to be ok (jus checked visually, i don know how to test with multimeter and i don have one)
1. checked power cable, working fine.
2. vga cable working fine.
3. backlight glowing, shows acer logo and no signal or cable not connected msg.
4. power led working, sometimes blue when showing cable not connected msg or sometimes amber when showing no signal.
5. some solder joints in powerboard not seems to be ok. it looks really bad with holes in it. check the pics for details and let me know is that bad solder joints.
6.checked all the cables including cable from lcd for improper connection (with small led buld and AA battery). everything seems to be ok, no broken wires.
kindly check the image guys. looking for help.
