Re: Help identify varistor
Thanks.
The previous converter failed so maybe took this on the way.
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Re: Help identify varistor
It is from Galmet wood pellet boiler controller.
Apparently it was left switched on all summer in tripped state. When it trips the LED backlight is not visible so looks switched off. Wood pellet boilers this year are very popular in our region.

Re: Help identify varistor
Seems it is not the problem. I got voltage drop on input so the converter shuts off after some 5 minutes looking for cause.

Re: Help identify varistor
Double checked yes it is parallel to AC.

Re: Help identify varistor
So this is not inrush current limiter?
How to verify if it is not bad?

around 7mm yes
looking for replacement.
I have SCK 053 as spare or it is not VDR.

Re: Bosch AL 1830 CV(AL1830CV) blown fuse
Replaced FET, R7 resistor, fuse and it is still short. Blew fuse and R1 thermistor(8S150L).
Need to look further.
You where right it was not so easy.
edit: two of IN4007R(or 1N4007 ?) diodes are shorted. Should I replace them all with UF4007?...Last edited by otoluk; 10-10-2022, 12:19 PM.

Did you find a replacement FET or analog?

Re: Bosch AL 1830 CV(AL1830CV) blown fuse
V5 Mosfet(ST P6NK90Z)is short on all pins.
Mains cap(C2) is ok but while others are FZE, FZK and GF series this is noname Acon.
Inrush limiter has same pcb coating which is cracked but part is ok.
Thanks this was unusual as also it is isolated from V5 by
plastic gasket. What for as it limits heat transfer?...Last edited by otoluk; 06-09-2021, 01:31 PM.

Have to also decode resistor near V5

Fuse blew with nice sound effects. Seems need to replace fuse and resistor. No schematic is available.
Not sure what have caused this will try to replace 400v cap, resistor and fuse.Another victim of planned obsolescence.

Re: [Philips TV] 47PFL5604H backlight/inverter
Where did you find element values?
I am looking also for D303 and D908 values. D303 has marking "5D" that is all i know.
