Here is the sketch with the IC. Injecting 3.3V to 0V pins, i have 0.03A drawn from the power supply. for me is a litle high curent.
Also, injecting 5V to 7 and 8 pins, the IC is getting hot instantly. with a lower voltage the IC still get hot, but not so much
Any ideas? Thanks​

Bose soundtouch 30 no power on
Hi guys, I have a Bose Soundtouch 30 to repair and I am stuck. I have 320V from the PSU to the mainboard, 24V on the amplifier, 5V and 3.2V, but pushing the power button, It is not powering on. I found a chip that it is heating when i plug the speaker in the outlet, but i can not find anything about the chip - C4E smd 8pin chip. It is anyone with some experience on this type of Bose to help me with some ways to find the problem? Thanks -
To me it looks to be a screen problem. Try to start the TV with the left ribbon cable from the Tcon out, and see if half of the image is correct. If it not correct, put back the ribbon cable, and take out the other one. Power up the tv, and see the picture. If the picture is ok, you know now what half of the screen has problems....Leave a comment:
