Does not turn on, power supplys ok, display on, sometimes the spectrum analyzer also lights up, but does not turn on. | After a lot of cold soldering, I verified that the 5v was not reaching the computer, looking carefully, I found a bad ud25 (1n4007), and the 5.5 x 0.47f super capacitor had a short. I took advantage and also replaced the electrolytic capacitor below the display, parallel with the uzd1 | Ud25 (1n4007), uc6 (super capacitor to maintain the clock and radio memory, 5.5v x 0.47f) and the electrolytic capacitor under the board, in parallel with uzd1 (47μF x 16v) | Trendset |
