It turned on without image, normal LED | In this model, the screen voltages are generated on the main board, I had the fu2 open, I found the capacitor c29t short, I removed it for testing, it released the voltages for a while it worked but soon it stopped giving an image and VGL was zero and VGH dropped to 13V, At first I noticed that when turning on the two voltages they appeared normal then they changed, the u5t heated up when measuring the circuit around it again I found the c21t shorted, I removed it and it worked normally. | Eletrônica Mirage | |
