Novice trying to repair a Samsung plasma TV with the clicking non-start problem. I've replaced the visible blown/domed caps on the power board but the problem remains. I think I have identified the problem cap/s as I can start the tv after heating these 2 caps with hairdryer for 15 seconds, starts up and works perfect for the whole day no problem. I don't know which is the culprit so intend to replace both. I have sourced the aluminium cap 5v 22uf no problem but I cannot find an obvious replacement for the small brown one. The only markings are 1J with 104J underneath which I believe is 0.1uf 5% tolerance. The problem is I don't know what type of cap it is, presumably film type, and I cant find a similar looking one online.
1) can I change to a different cap of the same specs ? e.g. ceramic or ali.
2) is the voltage critical? it is on a 5V switching circuit but film caps seem to range from 50v upwards.
Any advice would be appreciated.
PS. the white gunk is mastic which I cut away to read the labels. the label on the can cap is cut as I tried to remove it to read. The brown cap in question is about 8mm square with inner kinked legs spaced 5mm
