Question about Samsung HL-S6168WX DLP TV
SAMSUNG DLP SOLUTION. this will fix your problem. I fix a similar model to Samsung HLS4666w model. Chasis number bp41-00278a as printed on pc board. I added capacitors to each of the three dc to dc converters on the main board. You can download the data sheet for ic212 (MP1583dn). Main board is where all the external connections are made from outside). Remove the metal cover which covers one third of the main PC board. To test this fix, only one of the dc to dc converter needs a capacitor. Location IC 212 is the dc to dc converter of major interest and will fix all problems. Add a capacitor on top of capacitor presently located at location c217 as printed on the pc board. Do not remove any old capacitors at these locations. Be careful with polarity of capacitors. Do not place this capacitor on the ic pins of MP1583dn. The voltage at location c217 should be STB 3.3 volt. You could also place the capacitor at location BD212 (+3.3) and ground, instead of on top of capacitor, if you need more clearance. BD214 and ground for converter ic 213 or on top of capacitor C236. At capacitor C212 for ic211 or at BD210 to ground. The value should be 33 uf or more, anything less will have limited fix. I would not pass 60 uf. I place a 33 uf capacitor with a working voltage of 35. This fix not only work for popping noises from speaker, but it also improve the colors. Solder with caution, leave no speck of solder behind. good luck. search the web for free service manual. Just solder the wires on that hatch door switch.

I would check the speakers see if the anything is getting hot, take back cover off make sure you dont look at lamp. Tape down switch to lamp door and see whats making noise.
