After which it worked for a month and the fault

[shapanqqcceqd]

appeared again. In the workshop, nothing was done to the TV, apparently as a result of shaking
or random movements, the contact was restored for a while, and after a while
it disappeared again. Therefore, I have long made it a rule for myself, after a general inspection of the installation, I conduct
a thorough inspection of the soldering points with a magnifying glass, since many faults are hidden
here.

FUNAI TVR-2000A-MK7 . Monoblock. Poor TV start (sometimes does not turn on).
The malfunction progresses until it finally does not turn on. The fault lies with the electrolyte in
the power supply C08 100x25V, connected to the 6 pin. regulating microcircuit IC01 and the hot
ground of the power supply.

FUNAI MK — 8 periodically switched to standby belgium telegram data mode. Managed to notice a change
in voltage on the 16th leg of the TMP…R584 processor. Zener diode D283
(connected to the 3rd leg of the TDKC) was under leakage.

FUNAI 2000 MK10 . Does not turn on, the key transistor is intact, no short circuit in the secondary circuits.
The reason is a leak between the K-E Q621. It controls the LED in the optocoupler.

FUNAI 2000 MK 8 C3979 burned out. The installed one suffered the same fate after 2-3 seconds.
Installed KT838A. It heated up more than usual. Under load (bright scene or 150 W bulb)
the voltage from the power supply dropped to the standby mode. The reason is that R609 increased
the nominal value to 100 kΩ.

FUNAI 2000MK10 . Defects: the frame rate "twitches" when the volume is increased, the brightness
is reduced. The frame rate is powered by a 9V stabilizer, which for some reason
only received 9.5V from the power module at the input, while the 11V indicated on the diagram. Moreover, all other voltages
are normal. I replaced all the electrolytic capacitors in the power supply, at its outputs, in the stabilizer.
