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. Orion T-2188MJ 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.
