Dave & David2 replace the bad caps in the old LG 50PF3DF 50" plasma TV found in the dumpster here: https://www.youtube.com/watch?v=FPK1_hy4KMU Will it fix the problems? Also an impromptu tutorial on how to replace bad/leaking/bulging capacitors, and measuring capacitor ESR in-circuit. Plus bonus banter.
NEW screencast type tutorial!
Let me know what you think.
NOTE: The plan is at least several of these tutorial videos per week consistently. So on my main channel that frequency could swamp the other content, hence considering a new channel.
An introduction to digital logic, digital vs analog, logic gates, logical operators, truth tables, timing diagrams, and the dreaded boolean algebra.

Part teardown, part repair, Dave looks at an Australian designed and manufactured Ness D16X alarm panel that has failed.
What's that smell?
Can it be fixed?
How do you repair solder mask on a PCB?, or add solder mask to your own home etched PCB's?
And another look at PCB spark gaps.
