You can do it with a multimeter (ohmmeter).Thanks a million I will do that! You probably just saved me $80. Do you have any tips on checking components with a multimeter or a link I can check out. I find it hard to check things like capacitors since sometimes they can be in parallel with another capacitor or situations like that.
No, the tolerance of electrolytics is very wide - and the larger the better in this case.Alright, I also checked the caps they seem fine. The two larger ones are in good condition. One reads around 5,000 uF when it's rated 4,700 uF is this an issue?
Alright I'll test that.check the speaker too make sure it's not shorted or open circuit. with a shorted chip, a bad speaker is also likely
Alright, will do.Did you check the TDA7294 for any internal short? Just measure the pins 13 and 15 those are the Vs- and Vs+ (if short then your ohmmeter should show ~0 Ohms)
You can also measure the 13th and 15th pins on the pcb while the TDA7294 is not soldered to check if the short is coming from that IC or if it's still available.
Or might be that the IC burnt something else there also
I know, I guess I was holding on to the hope that it wouldn't be the ic. Also with school and such time has been a little issue. Also I did not actually get them until Jan 6.Your original post was Dec 2nd - you should have changed the chip on Dec 3rd
As a professional service engineer the first thing you would do with something like this is replace the chip - the odds are high that that's what's wrong, and it saves time and money to replace it first thing.
