The vertical only opens the bottom | 3465 smd resistor (it is connected between the + of the 2463 capacitor and the base of the 7465 transistor) | The schematic shows 2 330r in parallel, but I found one with just 150r (you can use just one with 150r), remember that 1/reqv= 1/r1+1/r2+1/rn. | Ailson |

Doesn't start. power supply does not oscillate. the defect was the 30k r801 that was measuring 100k. After swapping for 2 15k in series, it worked normally again. | Gilcimar Rocha Pereira | ||

No sound and no image with horizontal output transistor shorted q501 | When replacing the horizontal output transistor q501 burns out immediately. | In my case I had to replace q501(2sd1632), c511(peak capacitor) 8200pf and also the flyback(tlf15564) simultaneously as they were all burnt out. It is good to check all capacitors and diodes of the horizontal output and also the 180v line and finally check the +b 140volts. | Otacilio |

Sound coming and going depending on turning on and off and sometimes no sound during programming. normal video. | Replaced capacitor 805-10ufx160v. | It was open, causing replaces in the voltages of some circuits, I replaced it with 33μFx160v, because I didn't have the 47μF one, as they said to replace it. I also replaced c309, as the cover was completely shrunk due to the heat and had low capacitance, I inserted an x6 | Luiz Fernando |
