Check T505 A1023. Measure the E, B, and C pins back and forth without any penetration. During standby, the T504 collector should be measured at +7V/the D504 cathode also measured +7V. T506 was also measured without a short in the E to C pins. The resistance of R516 8K2 also did not increase. It turned out to be due to the 2V zener diode D514. It can be replaced with a 3V3 if necessary, as the 2V diode is missing. The diode was measured to be leaking. 1,048/1K more, measured using a diode scale with the red probe tip positioned at the cathode/with a black ring at the tip, the black probe tip at the anode leg of the diode, replace R517 180 ohm, D512 5V6 also D514 2V/replace 3V3 the TV starts, thank God click... Additionally, if the T504 collector still measures +18/+20 voltage during standby, try checking the T506 collector leg, during standby it should measure 0V if the +2/+3V voltage is still measured, check/replace D511, and C516 102/1 N primary PSU..

The lower the voltage, the faster. The voltage required by the STB chipset starts at 5V and is then reduced to several voltages. The voltages that must remain present are the v.core voltage of 1.2V and the controller voltage, BIOS 3.3V. Voltage 1.8V is the VDDR voltage. If the stepdown IC is 1.8V, it means the chipset uses DDR2 memory. If the voltage is 1.5V, it means the memory is DDR3. On the Matrix DVB2IP STB, the VDDR is 1.5V. The difference can be felt more quickly; changing channels feels different from its older sibling, the Matrix Merah. If you see a 1.3V stepdown IC, it means the memory is DDR3L. The...
