Phillips LCD Tv no power, blowing fuses

[Spankers]

Hello all,

I need help repairing my Phillips LCD tv that was damaged from a lightening strike. It shows no sign of life. I opened up the back and noticed the fuse was blown so I got an exact replacement and as soon as I plugged it in it blew instantly. I noticed some burn marks on the green side of the board. I am attaching pictures. Is this TV done for?
Thanks

The burn marks look like solder resin, nothing to worry about.

If the power supply is popping fuses, this means you have a short somewhere. Possibly a shorted transistor, maybe more.

The TV repair board is a better place for this post as it will likely get more attention there. Maybe a mod will be nice enough to move it there.

You most likely have one or more shorted components on the hot side of the power supply (or "PSU" - board with the bad fuse). If you look at your PSU, there's a dashed line that divides the hot side from the cold side. You may also have damage to the main board, but the PSU should be examined first. Sometimes, it's as simple as the large cap needing to be replaced.

Questions: What is the model number? Also, can you post a pic of the circuit board layout and pics specifically of the front and back of the PSU?
