Hello, i'm master tang. This video, which was used to repair a 920-high-peaker, has been removed and, according to fans, the machine exploded without electricity。
• first step, to measure whether the magnifying tube, 2x3, 2+94, was punctured, short-circuited or damaged, using a universal meter. After measurement, the magnifying tube was punctured, short-circuited and damaged. Right-channel magnification tubes were punctured, short-circuited and damaged. It's dark and dark. Can you fix it
• the following is a one-size-fits-all watch to identify the active magnification tubes that are punctured, short-circuited or damaged, and the electro-blocking amplification tubes are measured at a triangulation value of less than 03. The measurements revealed a rise to a damaged public magnification tube. The measurements revealed that the diodes next to a g bt were completely destroyed and 10 e-axis were broken。
• remeasure, a gb t-barrel short circuit, with both chips replaced. The initiation of a thorough screening of chips and peripheral circuits and the introduction of an electric switch to observe the dim amount of light bulb oil indicate that there are no visible short circuits。
• a single-size-fits-all meter measuring 13. 9 volts of electrical power. A test monitor is used to measure whether there is a kick-starter wave at the angle of igbt. An additional measurement of the presence of an instant vortex-starter wave will allow the installation of agbt. The positive and negative voltage of the measuring magnification tube is normal, and the bias voltage of the operation tube is normal at 469。
In the case of damage to a power magnifying tube, only the dismantling tube can be matched, which is similar to its original parameters. It uses a tube that is more expensive than winter。
Every one of my maintenance videos, so many old irons broke their hearts for me, you didn't carry a fake load, you didn't have a side wave, you didn't do the finish, and none of that matters to you. Each machine is repaired with an aging test, and it is normal to deliver to a fan friend。
This video is shared here. Thank you for watching and for the attention of your favorite friends. Thank you。
