The boost regulator is on the BACK of the control board - there are 2 look for the one with the large chip capacitor beside it... that chip cap is the problem...replace it... you don't need a chip cap so you can use any tantalum with leads 10 uf with voltage rating greater than 10 V ... works...

With my 46 inch Samsung, I found that the "boost regulator" on the main control board had a bad chip capacitor. I changed it using a small 10 uf 50 V tantalum capacitor (watch the polarity)...and all is fine. The boost regulator is a MP2363DN and the large chip cap is immediately beside it. The...

The boost regulator chip is on the back of the control board by the way. On the front there are 2 ferrite coils and the chip is directly behind... on the back there are 2 but the one has a large chip cap beside it with a band on it... that is the little culprit that causes all the grief....
