If it is a GA-4M chassis, use smd micro jungle marked IC1001. + 8 Vdc on pin 44, (100 uF / 16 V-c829), and on pin 12, (c807-330uF / 16V). From regulator IC801, switched. I suggest you check this voltage and change these filters; They feed the video process. In addition to what was mentioned by manolo karvalo.

The solution was supplied by cop2017 and for a rebound of the keys of the PC I attributed it to manolo. There must be a way to correct this error! Regards cop2017. Even when the chassis is not the same, I replaced the 330MFd / 16VDC and 47MFd / 16VDC capacitors and the noise in the video was eliminated. Thank you!

Hello Friend. check the filters that are close to the flayabck and solve the flayabck pins and the socket of the socket the white color that is in the plaque of the trc .. and carefully resolved not to leave pins attached to the pins of the ic. Chroma already solved the choper pins and those of the ic. Vertical these if they are with cold welds and if there are bulging or inchado filters change them. luck and regards
