Techwood 22FHD Combi - power surge / lightening strike damage ?
DenisM:
Attached is a PDF of the PSU - found on the net :)
Gives me a place to start ?

DenisM:
The component that is obviously damaged is a STR-W6253 -
described as a "230 Vac Input PWM Switching Regulator"
Perhaps there is a repair kit for this PCB ?

This is a pic of the PCB.
IC 800 has a hole blown in it :(

DenisM:
Would this boards be a suitable substitue ?

only 17IPS17-2 I have seen
Fault Symptoms: Set dead
The Cure: The T3.15A wickman fuse (F800) was o/c caused by two of the bridge rectifier diodes having gone s/c, I replaced all four with BY133 diodes (D800-D803).
