Samsung Model: SPN4235

[Lordlindsey]

Having a problem with this set. Hoping to fix it myself, with a some kind guidance from the great people around here.

No picture.
Power light either lights up red or flashes red but no picture whatsoever.
Can anyone guide me as to how to diagnose this?

Would be appreciated.
I've been laid off since April and would like to fix this as cheaply as possible.

also, anyone have a link or .pdf file for the service manual?
