3636 color television send panda easily breakdown
Breakdown of of phenomenon of serial number breakdown may produce place crux to choose account of test data breakdown
1 smooth canopy just appeared to involve Electromechanical cause automatically namely, line scanning circuit measures voltage stability, and IC801 (31) crural voltage rises everywhere. 5V R641 invalidation
2 brightness out of control, shine too and have full a flyback line picture tube and inspect discharge road to measure Q851~Q853C extremely voltage controls C806 leakage of electricity for 12V only, l851 opens circuit
It is normal that 3 searches show but without TV signal high frequency tuning or circuit of intermediate frequency enlarge measure end of VT of high frequency head not to have voltage IC101 puncture
4 image shake up and down oscillating circuit measures a scanning or field IC501 each foot and IC801 (24) ~ (29) crural voltage stabilizes C501 capacity decrescent
Clavier of diving tower of sex of 5 random laws is controlled, demodulation is put in or VT controls voltage of VT of undesirable and high frequency head fluctuant XS09 is undesirable
The interference of occurrence horizontal stroke of mid and random law takes 6 picture a scanning output or power supply are undesirable measure IC501 (2) (7) crural voltage beats substantially leakage of electricity of time capacitance C501
Indicator light of 7 power source is bright, switch on the mobile phone show 3 be controlled without CPU or N1101 of circuit of lead plane power source (9) crural 0V damages for 0 N1101 to terrestrial electricity block
8 audio are normal and measure XS10 without grating picture tube and line scanning circuit (4) the foot does not have voltage R648 sealing off
9 black and white and normal but matrix demodulation is not had sometimes when color or hue spends control to measure IC801 (10) ~(15) normal X801 of each foot voltage is undesirable
Indicator light of 10 power source is bright, switch on the mobile phone show 3 be controlled without CPU or it is normal that circuit of lead plane power source measures D709 voltage, and Q701E extremely output without voltage
R725 open a way
11 audio are normal, and image blurs and power source of periodic contractive switch or scanning output circuit measure B voltage to control wave motion in 90V, and other square normal D707 are undesirable
Indicator light of 12 power source is not bright, show 3 measure XP11 each foot not to have voltage T1201 primary open a way without power source part
Indicator light of 13 power source is bright, switch on the mobile phone show 3 without, close machine power source of squeak lead plane or line scanning place measure circuit of lead plane power source not to have voltage D708 puncture each
14 have audio and measure about circuit without image line scanning drive tubal Q604C all right extremely open circuit without voltage R635
15TV, sound frequency result all is not had when AV inputs signal discharge road measures IC301 (3) the foot opens circuit without voltage R15
