Horizon (HORIZONT) 655,
656.

And similar to the video on ILA8362A.
Another reason for the lack of serviceable Vertical video processor and
personnel mikruhoy:
31 In the absence of voltage, which is to configure the tuner. This voltage is
applied to stabilize the circuit size screen (43 foot ILA8362) through resistor
100k.




HORIZONT 21AF4 SHTST-739M1-6
There was no food. Replacement:
VT800 - STR4NK60Z, R811 - 4.7 - 7W, R812 - 100 - SMD, DA800 - UC3842.
The reason for failure is unknown, but in this model, there was no capacitor
S823-470, 140 volt circuit is installed.

No staff. Dried S607 100 * 50V, replace the effect of zero. Replaced tda3654Q,
appeared personnel, there is no OSD, picture and sound. 470 * 25 S831 (R = 2nd)
and 470 * 25 S833 (R = 3,8 ohm), 100 * passing S701 50V drain. Replaced
capacities, including a OSD, picture and sound. After a 20-30sekund care
settings. Found burnt R127, replaced with the corresponding face value and
power of 2W 15kOm. Worked for 1 minute and again care settings, found a cold
solder on 31B. In the MCR-656 adjusted the size and geometry. 2:00 run. All
clear.

ITeko 21A21, clone HORIZONT ch. SHTST-739M1
Ingredients: TDA9351/PS/N3/2/1855, 24C08WP, KS-H-148 EA.
TV sound is switched on and white screen. C827 100mkf (ESR-3Om) replaced,
initialize memory, set accelerating and geometry. It's OK.

problem manifested itself with progrevom.Iznachalno TV works
no questions asked after 10-min began to lighten the screen and in the future

If you lost a rare or color, and the replacement of transistors on a computer
does not help to replace the glass in their trim Dida KD522.Bylo several cases.
Continuity diodes gave nothing, they are nipped in the raboty.I telly worked
fine for weeks.

After the storm. Was replaced by the processor, TDKS, memory, TDA8362A.
Is not included with the keyboard, although there are pulses of the survey.
With remote control included - black screen, no graphics, no reaction either to
the control or the keyboard.
Malfunction caused by VD408 - leak in the circuit 20 O PCA 84S641/068.
Able to check only after watering of the board.

Fault on the line, turned out to FBT.
Replaced BFC22-23 in PET22-23, so you can put TDKS-31-05, 154-177B
Info mainly for beginners.
