Voltage of the LEDs at 67v, causing premature burning.Replace the rr08 of 2r20 for one of 7r5 and the rr09 of 3r30 for one of 5r10.By exchanging the rr08 and rr09 the voltage from 67v dropped to 60v, as each LED works between 6 and 6.4v the voltage remained within normal limits for the component.Gabriel G.T.

Missing the green color: after solving another problem already mentioned in another tip that was already shared sound, the TV turned on, however, with the image missing the green color in the image.On the kinescope plate (tube), I found the resistor r522 (22Ω) open... and the 3 transistors I resolved the es of this line (q507(bf422), q508(bf423) and q509(bf422) short or open, I changed the transistors and the resistor, I resoldered the board and it failed.Eletroboy

The standby LED would come on, when pressing the on button it would turn off, the LED would go out, the relay kept beating and would not turn on; I noticed that the power supply that feeds the horizontal output went up to 170 volts.I replaced the photo coupler, tl431, and the transistor q606 and it didn't solve the problem. After researching for a while, I found the c634 capacitor (in the second part of the chopper) dry, (without capacitance) I replaced the damn thing and it solved the problem.I took advantage and replaced the filter capacitors on the chopper transformer secondary... and those on the horizontal output, they were all with low capacitance... they were still the original ones from the factory.Eletroboy

Does not turn on - stand by led on but does not oscillate horizontally +b with 82vHorizontal output transistor shorted between base and emitterMeasuring the horizontal output transistor in the circuit leads to the wrong conclusion due to the low resistance it normally presents.Matões A. Técnica
