ERISSON 2120 chassis 3S10
Do not set the channels. When auto-tuning to the station as there is no
synchronization of lines and for personnel, Picture-b / (channels do not
remember them, and simply skips).
On examination, turned out to be nepropay choke L301 and burnt parallel to the
R325. At first he thought that there was a failure of memory, but went into the
service (MENU-> AV-> ANAL) no deviation is not found.
Checking the circuitry and the video processor TDKSa STV2248C concluded that
the failure of the latter. After replacing the unit STV2248C earned. PS: put
the socket on the percent of the large number of marriages in the market (me
luck the second time). Who in the position of S009A is "lit" 100mkF -
change in 10mkF to prevent future failures of memory.

BP is in the dressing. Power + V = 180volt 110volt at a rate. Leakage of the
transistor Q904 = 2SC1815. After replacing it, and replace R915 = 1.5Om
standing on the chain + B - all returned to normal.

When you turn on the TV LED turns on, the screen is dark, no sound. BP + B at
the output is overstated by half. electrolytes S917, 922,924,403 inflated.
defective Q 406 2SB764. At 110 is connected to the lamp 220V 60W. When you turn
on power supply goes to the dressing after a while the voltage is stabilized.
In a GS 904 replaces Q 2SC1815, including a network of power supply is working
fine. Replaced IC 801 42 351 LA sound is. Thanks to people who share their
information on the site.

When working swims brightness, the appearance of very bright scenes goes into
the duty room. If you reduce usoryayuschee or decrease the brightness, works
fine. OTL circuit test results are not given. The reason turned out to be much
easier to break-filter capacitors of 112 in. After replacing the TV will
function normally.

Defect with an ideal image jitter performance info (menu, channel numbers,
etc., etc.) Change C432 (in personnel voltdobavka) resolved the issue.

Turns on green screen with ERISSON, slowly (5 sec) increases the brightness,
the screen fills with green without Lough. If you reduce the Screen - the
screen gets dark green label. No sound on channel change responds. At the
output of the EP - R - 2,2 B \ G - 4,3 B \ B - 2,5 B.
To eliminate the need to replace LA76810A.

CQ0765RT, TV has started everything worked fine, but after turning off the power
button again does not get started PD Litas checked. After a long break the TV
switched on, but after turning off the power button again, no run BP.Kogda he
did not run it nebylo voltage chip for running 18c, replaced the zener diode
D614 at 18c and it all went, although he had been a zener checked, and after

RF works by normalno.Po AV - no signala.Esli disable "blue
background" - a signal to the AV goes, but not synchronize.
Replacing the GPU STV2248C solved the problem.
As it turned out - the client connects to the hot Tricolor.

The power supply will start momentarily inflated with output voltages (instead
of 110v-140m, instead of 20v-25v, 5v normal), and immediately goes to the
defense (at the output = 0 v) - problem solved by replacing tattered resistor
R642 = 100 ohms in the circuit of optocoupler .

Flashed TDKC BSC29-3807B and dragged behind a chip kadruhi TDA4865AF. TDKS
mother was not. The client literally breathed into his head, so I had to
improvise from what it was. With success has been installed on BSC25-N0809A
AVEST 54TTS-04 c minor refinement, which was to domotke at the core of
auxiliary winding 10 turns connected to 7, and 9-pin TDKS. Instead, calmly
walked TDA4865AF TDA4863AJ.
Then read on the Internet that BSC29-3807B is a direct analog-6174V-6006M (n).
Means possible without altering the reverse replacement in Avesta.
