This Toshiba 2998gms came into the workshop with vertical problems and the color blue predominating. these problems were easily repaired. After it was ready, when turning it off using the control, tsound would be a horizontal strip on the screen, as if the vertical had been closed, for about 5 seconds and little by little it would go out. If it was turned off by the main switch this would not happen. | The problem was in power/h-vcc. resistor r841 (5k6 x 1/6w) open. | Paulorusso | |

With some lines at the bottom and as it heats up, the lines increase as if it were a vertical outlet and it heats up a lot, meaning it will burn out. If you've already done everything and haven't decided, change the capacitor. | Change the capacitor c314 which is on pin 1 of the vertical output to ground. Then you can make a deposit into my account and just | itan(cabeça) | |

Horizontal problem | To test the horizontal, release the base voltage of the transistor q830 by disconnecting the transistor q432 and make sure that 9 volts appears on the collector. This voltage feeds pin 17 of q501, generating a square wave on pin 13 that goes to the base of the horizontal drive transistor. | Miltom |
