Hello,
I have a Samsung LN40A550P3F 40" HDTV. Bought in 2008, so it's about 10 years old.
For the last couple of months, it's been slow to turn on in the morning. I've timed it, and
it's anywhere between 5 and 10 minutes. The TV has a red power light that continuously blinks
until the TV turns on.
I recently took the back off, and looked at the caps, but they all look ok to me. No bulging caps.
I'm the original owner, and the power board appears to be in pristine condition.
I didn't know what else to do, so I bought a "refurbished" power board from ShopJimmy for 50 bucks.
They sent me a beat up board, dusty and scratched, with the corner of the circuit board cracked and
hot-glued together. This was the first time I have ever used ShopJimmy, so I was shocked they
sent me a Frankenstein board.
Anyway, I replaced the power board, and after a day or so, nothing has changed.
The TV still takes several minutes to turn on in the morning.
If replacing the power board didn't solve the problem, what else can be done?
Another question, what exactly happens when the TV is turned off and is in standby mode?
Should the TV still maintain the charge on the caps, so the TV can turn on quickly for the
next time? Thanks.

This board has two large 450V 100uF caps, and some other smaller caps. It also has a small,
removable fuse, described as T6.3AH250V.
