Problems Solved Using ESR Meter


SONY 29" TV the complaint was picture came out after about 30 seconds. I start checking all the electrolytic capacitors first and found 2 caps that have a high esr. One is in the power section-220uf 25v, the esr increased to 5.1 ohm while the other cap was 10uf 250v located at the horizontal driver transformer area. Replacing the two capacitors solved the problem as now the tv only takes around 4-5 seconds for the picture to appear. The esr meter is a real gem to me as it already solved quite a lot of capacitors problems and it already paid itself back many many times. For those of you who still haven't invest any ESR meter I suggest you to do so as it can speed up your repair work and no guessing game.
