Default Re: Fujitsu-Siemens P17-2, likely bad transformer but cant find specific model

That component is likely a power mosfet, Looks like AP4511GM , It may be the only failed component or it could be the high voltage transformer that it drives.
You can usually compair the resistance of the secondaries of the two transformers, if this transformer measures quite a bit different it might be bad also

Also have a close look at C147, it looks like there may be a dark mark on it, It might be bad, if it is bad I suspect it might just be the cap and fet defective
