Samsung LN46A500T1F - slow power on - alternating static lines then ok

Troubleshooting TVs and Video Sources - Badcaps Forums - www.badcaps.net
Looking for help on my mom's Samsung LN46A500T1F. This was previously fixed with a replacement Tcon board in 2014.

Lately it has been getting slower to turn on, it goes through like 3 attempts to turn on after I push the power button on remote. When it does turn on, it goes through a period with alternating lines of static, then finally goes to to ok picture and works fine from that point on until the next time it is off for a period of time.

Here's a video of the power on symptoms: (upload still processing when making this post)

Disclaimer for the Fox News. It's my mom's tv and that's where it was set!

I'm thinking it is related to power supply warmup.

Any ideas on what the problem is?
