hi i am a self taught repairer of basic electronic items and have been
doing it for about 4 years, as i buy faulty items repair them then
sell them on but i have a batch of about 25 PVRs i have repaired about
20 of them but there is one part on the last 4 that i need and cant
identify

It is on the power supply board

it is labelled RT1 and looks alot like a small capacitor

it has the marking 8S100L on it

it is one of the early components on the board (next after the fuse-
F1))

please help as i have repured the rest of the board but am sure that i
need to replace this aswell as it is showing scorch marks

It's a 'surgeguard' style NTC thermistor. Have you measured them ? They can run
quite hot btw.
