Re: Samsung PN50A510 P3FXZA Plasma Cycling On/Off

A friend had a PN50A510P3FXZA that was not working. A quick look showed that the RTE 801 and 802 (NTC's) were burnt. Closer examination showed cold solder joints on the nearby relay, which left the NTC in circuit all the time, thereby burning them out. I replaced the NTC's and also replaced both relays. I figured I was all set, powered the TV up and it started cycling on and off.

Found this forum, and replaced C102 with a big honking 47uF 30V leaded axial that I happened to have. There is plenty of room under the board...
