Chosen Solution
Hello, I recently came into possession of an Emerson EWC 1301 TV which a friend was discarding. It turns on for about 1-2 seconds and then turns off but seems to be working perfectly for that time. I opened it up and after safely discharging it I disassembled it and checked the board for any component damage visually. The capacitors show no visual sign of damage and the fuse seemed good, so I reassembled it and the problem persisted (at least I didn’t make it worse lol). Does anyone have any idea on how to proceed from here? I was able to change channels and get about 2 seconds of FFIII going on my snes. My best idea would be to test each individual capacitor with my multimeter but I’m not 100% sure on how to do that safely so I thought I should get a second opinion from here.
Hi @when_suddenly , CRT TVs work at high voltage so be extremely careful when testing. The fuse must be good otherwise it wouldn’t start at all. To test the capacitors you need to remove them from the circuit board and test them with the capacitance test function of a DMM, if your meter has one, or a rough test is to use the DMM’s resistance test function, just to see if it is open circuit or short circuit. The actual capacitance value using the resistance test will be unknown. You can test them “in circuit” with an ESR meter though. Capacitors aren’t always the cause of problems in TVs. Unless it is obvious as to what component is faulty e.g. heat stressed, burnt out etc, the best option is to get hold of a service manual for it which has schematics and start testing using that otherwise you’re just going at it blind. I couldn’t find a service manual for your model but here’s the service manual for an Emerson EWC1303A which may help. Hopefully it is similar enough (has the same chassis number?) to yours to be of some help.
