panasonic viera tcp60st30 SC board Transistors type or Kind ????

[Rudyrude]

Hi guys
I need a little help from experts
My 60 inch 3D tv recently started acting up
Till it died
So I found the problem it was very easy to identified
And it was SC board ( TNPA5399) transistor that went bad
Now my Big question is
How do I identify or how do I buy this transistors (see attached pics)
I Know nothing about transistor world
Hope you guys can help me out

Are you sure that's the only transistor that is bad? I cant imagine only one is bad.

Did you measure all of them?

Can you post pictures of the whole board?

Thnks Moreno83 for reply
Like I said
I'm new in all this boards caps transistor etc etc
I have a multimeter but I have no ideó how to use it
And then if I figure it out , do I have to the transistor out, in order to measure them ?

Well , these 2011 models all have the same problem.

What you see on the boards ( unless you soldered ) is flux/fluid from the factory when the board was made. Nothing special although the solder looks like its gone.

Meter in diode mode and measure the outer pins on every IGBT ( Q )
For the DIODES ( D ). black prope on middle pin and red on 1 of the outer pins , again beep is usually bad.
First picture , measure the 6 fets around the white prong connector. Cant see it clearly but will be something like Q422.

Ps , set blinks 7 times?

Also , what happened with the tv and how are you sure its the SC board?

Measure Q401/402/403 on outer pins in diode mode. Same for Q421/422/423.

Thank You for reply
So the way I figure it out
Light was blinking 6 times
I saw shopjimmy code explanation video

After I followed their steps
It turned out to be that the SC board was the problem by the light code

So now
I measure all the Q And D
And all seems to be good
Except
Those 2 burned transistor Q451 and D461
You think one of this transitory will fix it ? (See pic attached)
If not how can I get them ?
Thnks again

You are not going to find any of them in the Radio Shack bins.
You should do A LOT of reading from previous posts on this site.
I took electronics for two years in high school, 28 years ago. I knew nothing about tv repair, or troubleshooting.
I have spent the last two and a half years reading and learning from people around the world, ranging from 88 years old down to 17.
You have got to do the research, read every thread for your tv, and watch every youtube video for your tv. Then watch every video on how to use the tools you have, how to test the parts in your tv, and tips on how to repair your tv.
Radio shack ! I guess they are good for buying solder.

As Tvtimmy says.

You could order the part from mouser or on ebay. If you are 100% sure the SC board is bad then you could also buy a new one on Ebay. They are being sold for $40/50
