Peacock color television maintains example
From;    Author:Stand originally

This machine is core of machine of 3 foreign A3, discover V511/2SA1015 of power source part via checking, v512/2SC3807, VD515/PC817C, v553/2SC1815, VD514/IN4148, VD517/ES1Z, VD561/ uses 6V8, n551/AN7812, r569/4 Europe 7/1W, VD506/ERC05-10R, VD505ERC05-10R. V110/2SD400, VD110/10V, n101/LA7680. Shake path of scale down accusing a ministry changes tubal V01/2SA1015, v02/2SA1015, v03/2SA1015, shake accuse VD08/1N4007 of 12V power supply, l04/47 small go smoothly, high frequency head is bad. After changing, switch on the mobile phone burn a tubal V432 (2SD1651) , check discovery line frequency is exorbitant, change job of the television after X421/503KHZ is regular. But this machine does not switch on the mobile phone sometimes, check B to be 60V left and right sides, because this machine is used,close to drive power supply to shake all right accuse to close machine, because this runs V552 radical course in switch control,receive capacitance of 470-1000 small way to come defer switchs on the mobile phone can.

Peacock KQ51-38-4 color television

Some have color, some do not have color. Adjust intermediate frequency to disable via checking, measure color decipher piece LH3565 discovers 4 feet have color is 4.5V. 3.25V is when having color. 5 feet have color is 4.5V. 1.15V is when having color. Its at each foot voltage normal, transfer to other localities makes to be worth breakdown normally as before, w116 short wiring is pressed at the same time with the hand after (12V power supply) He Jingzhen inputs end (16 feet) color is normal, it is normal that color of this two places is received with 18PF capacitance after.
