No color in SECAM. As an additional symptom, it does not diminish to zero at
saturation PALe.Parazitnaya conductivity between the printed conductors going
to the 7 (saturation) and 11 (color system), the legs of the video processor
TA8659 AN, which arose
on leaked capacitor 1mkf 50V (6noga m / s TA8659 AN).
The problem may manifest itself in a spontaneous change
saturation, especially noticeable in SECAM.
No picture, the screen is dark, the sound is.
Loss of R560 (56k) on the food chain of contrast (26n IC 201).
ORION TV3782 TXSI ch. CTS-AA
Ingredients vidio percent - STV2246, mean percent SAA5531PS.S Phillips,
Phillips remote tadpole, although the scheme and manual appear under Orion.
Defect: TV can be switched on after 5 minutes if you keep on the remote or the
Start button lokalke. Checked all the litas, the replacement transistors for
running and eating, not what did not work. Bus is present then randomly
disappears. The same thing happens with food videoprotsa, then there is
something lost. Cured very simply changed the firmware. Firmware is taken from
the site. The service adjusted the size and switched to meters.
ORION TV2195MJ chassis
TM7397B Ingredients: OEC6047B; 24C04;
TB1226CN; LA7565; TA8403; FBT - FCM20B042
Typical fault for the chassis: The inclusion of a white screen. OSD is.
Gradually a few minutes starts clapping appear remarks image. Replacing the
capacitor in the circuit 470h25volt 5 volt regulator.
The image appeared only in the meter range with 1po Channel 5 with a few barely
perceptible noise in the form of fine horizontal stripes. From 6 through 12 and
UHF absent (solid noise and disruption of synchronization). Replacing the
capacitor S415 (470h16v) in the chain 9voltovogo regulator solved the problem.
