The number of televisions in use of all kinds

FUNAI MK10 HIPER The TV does not turn on from standby mode, R579 2.2 Ohm is
broken, after replacement it turned on, the screen is dark green, the raster is shifted to the left by 3-4 cm,
the capacity in the same circuit 4.7x100V is faulty, it is checked with a C-meter as working, after
replacement everything is fine.

FUNAI MK8 . ​​Malfunction - after turning off the TV with the remote control or the button on the face (switching to STBY mode), it does not turn back on.
When measuring the voltage of the power supply, they are greatly underestimated. Instead of 5V on the controller 2-3V. The diodes of the power supply D616, D615 turned out to be defective. It is better to change both at once.

FUNAI MK8 . ​​When the TV was running, the supply voltage increased sharply to 180V and
higher, which led to the failure of the high-voltage belgium telegram data capacitor line transistor .
Moreover, the TV could spontaneously switch from standby mode to working mode with
subsequent repetition of malfunctions.After 4 repairs of the power supply and line scan,
the resistor R 616 –2.2 MΩ turned out to be defective.

FUNAI MK8 . ​​When first turned on, it starts and works normally, but if you turn it off,
it will turn on only the next day. After washing the power supply with alcohol (
it was dirty), it turns on normally for an hour.
It turned out that the nominal value of the 10 mOhm resistor had gone down to ~20 mOhm on the gate of the field-effect transistor.

Schemes of pulse power supplies of TVs Funai 2000 MK7 and Philips 2021 their typical faults and repair
It is still too early to write off televisions on cathode-ray tubes (kinescopes). of models and different manufacturers is still huge and their repair remains relevant for many owners.
