So, these 4 parts have been replaced

[shapanqqccb]

We go with this part to the Mitinsky radio market in Moscow (at that time there were still stalls on the street) and the guy-seller in one of the stalls said that it is necessary to change 4 parts, because most likely not only this one burned out. And he sold a repair kit for 250 rubles, and advised to screw the SMR 40200 part to the radiator without a heat-conducting gasket, because because of it a parasitic capacitance is formed.

and the TV started working (and still works in this place - May 2020).

A few years later, an idea arose to test these parts for integrity. It turned out that all 4 died. The capacitor has zero capacity. The R2K diode is an avalanche diode, the task of which is to die with a short circuit and burn out the fuse when some part in the circuit dies. This is like fire protection. The SMR 40200 part also died: it has a field-effect transistor usa telegram data with an insulated gate (G) on the 2nd, 3rd and 4th legs, but in fact a short circuit is ringing between G (Gate) and D (Drain). That is, the transistor inside this assembly died, and people on the Internet even suggest fixing this by sawing this part in a certain place reby sawing off the internal transistor) and soldering it externally IRFBE30:

In general, here's what's inside HIS0169 and SMR40200 and what their meaning is: SMR40200&his0169.pdf

Repair 2
Problem: immediately after switching on the picture is very pale, then, after a long (2-3 minutes) warming up, the picture becomes richer to normal.

Solution: dead electrolyte was found in the space between the TDKS and the BP:

zero capacity. Replacement - the picture is juicy immediately after switching on.

Repair 3
While the TV is working, the picture vibrates at the edges, and a vibrating sound, like a cricket chirping, is mixed into the speakers.
