Vt-Voltage not want the road, damaged R734 33k.
-Contras did not function, damaged R345 220k, R436 10k (from abl).
-When the first on a normal image, then shrink the image then right-left horizontal lines or less, the voltage of 8V or less, check the circuit supply.
-Images sometimes do not catch the broadcast (TEG AGC 0), vertical fold lower, after a long time sometimes to normal, rather short 22nf C202 (52 pin IC TDA8361).
Color is lost, there TA8690AN IC pin21 r10k diseri then to GND with R10k, R10k is to replace the 5k GND.
-Did not catch the broadcast, Tr303, Tr309
Preview normal sound does not exist (kresek-kresek), but sometimes a normal voice, broken ZD STV2286 IC 8V at pin55.
No pictures, only horizontal line at the bottom of the screen, IC program is broken.
