capacitor markings ?

9505 is the component designation, and is typical of the way Philips do it. Their board ID's tell you nothing about what the component actually is, unlike other manufacturers who call their components " C " and " R " and " Q " . 9R0 is not a marking that I have ever seen on any disc ceramic cap. Are you sure that the device is not a thermistor or VDR ? What makes you suspect that this component is faulty ?

Replace all the electrolytic capacitors before you bother with the ceramics. (Unless you have tested the ceramic and found it bad.)

hi there Chaps thanks for the quick reply

more information , on furhter inspections, the silk screen printing always shows a symbol for a capacitor where a cap goes , but where this component goes it just shows 5 tiny squares although it looks like a ceramic cap .. it now seems it may not be .

and the reason i suspect its gone, it there was a large crack across the width of it , and when touched half of it fell off.

the faulty component is located near the front right hand side of the board , looking from the back and is very close to the on-board fuse.and very close to a red connector and one leg of this faulty component appears to connect to the deguasuing coil around the tube,

hope this explained a bit more ..

Oh yes ps i have changed a majority of the electrolytics on the PSU..

its probably a thermistor. 9R0 means 9 ohms. But if its part of the degauss cct it will usually have no noticeable effect on operation.

NT

Could be to reduce the inrush current, in which case the set will be dead if it fails.

Since the location of the device is in the front end of the mains input supply portion of the circuit this component is a NTC inrush current limiter, probably a nominal 9 ohms resistance at 25C.
