ViewSonic VX924 15 "LCD Monitor Replace SMD DK-QT Transistor MonitorMarca: LCD ViewSonic Model: VX924 Size: 19 "Inches ======================== Help With Transistor DK QT ======================== Hello everyone, the problem is as follows: The monitor turns off after a few minutes of power on Step 01: the motherboard with power supply was checked, the logic card turned out to be in good condition, the lamps are working Diodes were revolved, apparently the fault is in the card containing the power supply Step 02: all electrolytic capacitors were changed, the fault continues Step 03: 2 transistors of the SMD type were observed, with the following DK QT codes, 2 of them are at first sight are agitated and damaged, it is sought to find replacement, Step 04: the question is how can I find out which code or with which other transistor to replace, since it is difficult to find in electronics stores with this code SMD someone in the forum knows what transistor code corresponds to the DK QT What other tip can you give me to repair this monitor? The service manual is in: https://elektrotanya.com/viewsonic_vx924_vs10162.pdf/download.html If you require any other information to solve the problem please request it. Thanks in advance Already replace the 2 transistors indicated above, I made the arrangement like the one you see in the photo since the new tansistores are a bit larger, when connecting to the 127VAC light socket the monitor turns on and gives video signal but only lasts a second and it goes off, but the green ON button is still on all the time, unless you manually pay for the monitor with the off button it turns off completely but if I turn the monitor on and off again only 1 second of video and it turns off, so if I repeat the process of turning the monitor on and off it only lasts 1 second with a signal and turns off, STEP 2: The 4 transistors were changed, and the problem continues, the voltage in the main capacitor was measured and a voltage of 111 volts in direct corrienet was measured. Greetings Gürus from Spanish-speaking electronics, I look forward to your valuable contributions

Hello friends, I went to buy the replacement but I only found the transistor (SMD 2sc-4675-r) the question is that it is a SMD a little larger than the original with which the motherboard of the source came I will proceed to install it and then I send you a photo of how it is, of course I will have to engineer them to place it in a part of the empty plate and bridge it with some mini wires
