The malfunction is in the power supply

Having disconnected the frame, the TV turns on, the commands execute everything. When replacing AN5512,
it is necessary to replace the 100mk-35v capacitors in the harness.

FUNAY MK10 Replaced the L7PAL-3RD processor, and also Q621, Q106, R121, R122, C633 failed.After replacing all these elements, the result is that it does not start from standby mode. There is no starting pulse on the 13th leg of the processor. Reason: faulty memory IC102 (24LC02BP).

The malfunction of the Funaj 2000A MK8 TV is as follows: after switching on,
after 5 minutes and sometimes earlier, the TV goes into standby mode, although in fact
this is not a standby mode because the voltage on the processor is less than 5 volts, then after
some time the TV can spontaneously turn on, etc.
After replacing the diode D616, the operability
was restored, when ringing, the soldered diode belgium telegram data is completely serviceable, but if you drop alcohol or acetone on it
in the state of the TV malfunction described above,
the operability of the TV is restored for some time and then when warming up,
the TV again goes into hang-up. Replacing the diode solved this problem (KD522).

FUNAI MK-10 Brought in with a malfunction, did not turn on (the power supply died), after
restoring the primary (transistor, zener diode) worked for about 5 days, then the fuse burned
out.and everything all over again. My friend has the same case (also
changed transistor 3). The trick turned out to be simple in the power supply in the primary parallel to the transistor
(collector - emitter) the capacitance of 180 pF * 1 kV played a cruel joke, after the replacement everything is OK. TVs
have never returned, neither mine nor his.

When the TV is turned on, the line trigger pulses on pin 27 of the CXA 1213BS video processor disappear after 1 second. When the
Q219 transistor (line scan pre-stage) is disconnected, the line trigger pulses on pin 27 of
the video processor reappear. Do not rush to change the video processor. The defect is in
the line winding (interturn short circuit) of the deflection system.
