>>Something to save money---we found a fix for the ballast power supply in
>>Samsung DLP projection TVs, these seem to be same chassis---HLM4365W,
>>HLM5065W,
>>HLM437W, HLN437W, HLN4365W, ST43L2HK, HLM507W, HLN507W, HLN5065W,
>>ST50L2K,HLM617W, HLN617W, & ST61L2K.
>>On the ballast supply there is a vertical mounted board with four TO220
>>transistors soldered on it numbered 2SK3294. We found one of them
>>shorted
>>(10 ohms-all leads) out of circuit. You may be able to repair the board
>>while still connected to the main board, little tricky to remove it (we
>>did). The 2SK3294 does not cross to anything we could find, but found a
>>cross in Mouser web site. We ordered 3, put in one and the TV is working
>>great! The replacement transistor cost less than $1.00!
>>Note: You have to grind or cut off all but 3/8 in. of the metal tab of the
>>new part and solder it to the vertical mouted board. This ballast board
>>cost about $120 with shipping new, $1.00 for a part and little time to
>>fix.
>>Note: We were told that these ballast supplies are lethal, don't put your
>>finger in there when on!
