For something like the AV receiver's three capacitors or the TV's convergence IC's, how did you track down the problem and source replacements?
Are there debugging manuals for that level of electronics failure, or was it just "hmmm, that capacitor probably shouldn't have all the goo around it"?
- ryandrake 10y agoForums + Youtube + Digikey for most electronics repair. The ICs were a little specialty, I think I got them on eBay. For most anything once you get a hold of the part number, you're good to go.
- protomok 10y agoMy approach as a learn-it-as-I-go-DIYer is basically: 1) Google part number and the symptoms, half the time somebody has blogged about the exact same issue. These consumer products often fail in the same way. 2) Google symptoms and look for issues with similar products. Faulty capacitors for example is a classic cause of problems for older electronics and can be observed by just looking at the PCB (see https://en.wikipedia.org/wiki/Capacitor_plague https://en.wikipedia.org/wiki/Capacitor_plague) 3) Debug using Service Manual (note the User Manuals are typically useless / not detailed enough). Again just googling your part number will typically get you a PDF. If you still can't find the Service Manual you can buy it at these sketchy sites online for $10US, or buy the manual from the OEM (typically closer to $50US from my experience). 4) If still not sure what's wrong, buy a new logic board 5) Buy new gadget Warning - depending on which appliance is broken irritation level of spouse may grow exponentially!
