Sorry for writting in english, but polish is not my native language and i don't understand it.
Problem is, when turning TV ON, led blinks few times fast, then relay click, after that led blinks 8 times constantly. Im noticing this because I don't know its 2 errors, or just one.
I have opened the unit, made few measurements, R6666 0.1ohm is open and IC6604 MX0842 is short in almost all legs.
I have also checked R6614 and R6615, these are fine. Also checked Q6805 and Q6806, which are not in short.
Read suggestion somewhere in forums to check 135V rail and GND resistance. Its about 850-900ohm.
Thst's pretty much all what I tested. I will buy MX0842 and 0.1 ohm fusible resistor tomorrow (monday).
As this is my first CRT TV for servicing, and I'm pretty newb when it comes to CRT television, I'm asking here for help what to look next, before I replace MX0842 and R6666. Can the MX0842 alone be the only reason for this failure? Or there must me something more burned, which caused MX0842 to failure?
Im not new when it comes to schematics, electronics, soldering just never dig into CRT world. I don't have oscilloscope, just regular multimeter and soldering station.
Thanks in advance for any suggestion for fixing my first crt tv
