Re: Samsung LN46A550 Power Cycling
Really appreciate this post. I had the power reset cycle issue with my LN46A550P3F, for about 5 min before it would eventually come on. Replaced C102 and 131 and I am good to go!Saved - Element 24" LCD TV, Spectre x22wg-Gamer, LG Plasma DU-42PX12XC, Pioneer Plasma PDP-42A3HD, SONY KDL-55EX501Comment

Re: Samsung LN46A550 Power Cycling
I also just had success getting an LN46A550P3F working again by replacing C102. Thanks for this helpful post, budm!
I noticed there is a kit on Ebay (see attachment) for repairing these Samsung boards and it includes a replacement C102, C131, IC101, and a resistor. I wonder which resistor may need replacement?Attached FilesComment

Re: Samsung LN46A550 Power Cycling
Read the advice here from @bdum and several others and added a 47uF 16V eBay tantalum capacitor in parallel with the existing one on C102. Now, my old LN40a550 fires up immediately. The retirees I'd given it to were leaving it on 24/7 to keep it from turning green/screaming because it's their only form of entertainment, and iirc the TV is rated at 200W.
I didn't do any scraping, just soldered positive to positive and negative to the big ol' hemispherical chunk emerging from the PCB nearby as suggested on the forum. I have one new capacitor from my purchase remaining in case I need to add it to C131 on the other side.
I read this thread through at least twice, so thank you to all that posted before me.

Hello everybody, I could use some help on this one... It's got me guessing...
I took pictures of all the boards and the pin out of the connector on the power supply that goes to the main board... I measured all the pins in relation to chassis ground, here are the result.
