There were no oscillations on the quartz

[shapanwwuopi]

Then, instead of a small diode at +11V, I soldered in "what I had": MBR1045 (Schottky, 45V/10A).
To prevent it from wobbling, I covered it with hot glue. Result: +10.4 to the stabilizer and the frame rate is stable
at any sound.

FUNAI — 2500A MK8 . ​​The TV does not turn on after a long period of standing in the off
state. It is in standby mode, does not enter the operating mode, after several
attempts the TV enters the operating mode. And if it was possible to start it in the operating mode, then
the TV works normally for a whole day or two. During the defect, the power supply to the
control processor was +5.8 V instead of +5 V. or they were
unstable. The defect did not respond to heating with a hair dryer. Solution: replace the
D101 5.6 V zener diode in the +5 V bus stabilizer.

FUNAI — 2100A MK11 . The TV does not turn on, the standby indicator blinks.
If you load the horizontal scanning power belgium telegram data bus with a 40 W bulb, the voltage in the
power bus is 70 V in operating and standby modes. Solution: replace VD681 — 6.2 V —
leakage (located in the backlight of the power supply optocoupler LED), install an imported
6.2 V zener diode! Because the domestic KS162 does not work, the voltage on it is 5 V.

FUNAI 2100A MK8 Very bright raster with return lines and dark
vertical columns. Brightness is slightly adjustable. The owner says that after 4 hours
of operation, the defect gradually disappears. Voltage on the cathodes is 70 V. The supply voltage
from the rectifier from the split transformer is also 70 V. with a large variable component.
Reason: the electrolyte of the capacitor of the VVU rectifier filter 5 μF 100 V has boiled away.
