Re: Samsung plasma PN51D550 "red mist" pixels
I realize that this is an old post but I have used this thread as a help in repairing my TV (PN51D550 with about 7000hrs) with the same issue. I replaced the X-Main board (The initial issue was "no power on"...)but it turned out to be a worse board than the original so I replaced the shorted components (mainly MosFETs) on the original X-Main board , but was left with the Red Sparkles issue. In the end I also raised the Vs voltage from the specified 203 V to 207 V. So far so good.
