Hi, guys!
By the way. I have the issue with Thump TH-15A - woofer doesn't work at all. HF speaker works.
What happend before. Power supply was broken and on the CON3 was +50V and -50V instead +28V and -28V. As a result blowed up C227 (47uF 63V). After fix power supply (replaced U102 TL431) on CON3 appeared normal +28V and -28V. HF cpeker start work but woofer doesn't. I replaced C227 and TDA8950TH - still no sound in woofer. I found that on woofer connector CON2 two pins are shorted between each other but not shorted to ground. Also on both pins is -28V. I don't know is it normal. When I switch on whole speaker I can hear click sound in woofer.
Can some one advice me how to fix woofer sound, please?
