Re: Samsung PS51D550 51" Plasma - Issue? Any Help?

JRobinson your reading looks to be OK - I dont know what the actual value should be I no longer have access to he one I just fixed but 1.8K is not a short. If you flip the board over and check the resistance between each of the legs of the IGBt's if any of them are shorted your meter will display something like 0.00

I dont want to discourage you from having a go at fixing your tV but you will be fighting a loosing battle. The back of a plasma tV is not a good place to learn how to use a multimeter.

Re: Samsung PS51D550 51" Plasma - Issue? Any Help?

I just recent fixed one for a guy at work - similar symptoms to what you are describing the X main board was shorting the VS supply. I was unale to obtain genuine RJP30H and GT30G124's the ones on ebay were fake and blew straight away.

I enede up replacing them with IRG7IA3 which fixed the problem (6 IGBTs in all)
