Get the professional, although this won't be an expensive fix... You likely have one or more caps in the vertical circuit that are going bad... A cap acts like a battery in a circuit taking on voltage and releasing it at an even rate. When they go bad their ESR (equivilent series resistance) rises and the cap takes longer to reach it's op temp and work properly...
A tech with an ESR meter will easily find and repair this one...
no other issues only a minor problem..

it isnt the Y-SUS board, it is the Power supply, iv fixed this exact problem twice in the last month, try turning the tv on, and when it turns green, unplug it real fast, while light is still green, after 15 seconds plug it back in, then hit the power button, if it dont come on, hit the power button again, this time, as soon as it turns off, hit the power button again to turn back on, sometimes you can trick the tv and it will turn on, at least i was able to do it, and once it comes on, it should work fine, untill you turn it off again.

Normally, this happens when the TV detects a bad circuit board and goes into " Protection Mode ". The blinking red light should be a error trouble code. I don't have the Service Manual on hand for your model number to tell you what the code means.
Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.
You have a few choices:
1. You can try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route.
3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you red light blinking codes, circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.
4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.
I hope I shed some light on the subject for you.

Oh yeah, you can most certainly change the power supply by yourself.
It's easy to locate - just follow the power cable - and easy to replace.
Only make sure to let it discharge before you operate it. 10-15 minutes disconnected from power should do.
However, there's no guarantee that the problem is in the power board.
There is a very good chance it is, in fact, not there.
There's another board which commonly fails on many plasma TVs and the effect is exactly as you describe. It's called Y-Sustain board and you can tell which one it is by looking at the side of your TV and seeing which large board has manny plastic connections that enter the display on the side.
That board often has one or two fuses on it - I'd check those first.
