General recommendations for TV LCD LED repair
Possible manifestations of defects
- TV SONY KDL-32WE613 does not turn on and does not give any signs of turning on, does not respond to control buttons and to the remote control.
In such cases, you should start looking for a fault in the adapter power supply circuits.
The TV model under consideration is equipped with an external power supply Adapter 19.5V AC / D ACDP-060L01, the repair of which is not always advisable, but opening it and eliminating the simplest typical defects typical of modern SMPS is usually not difficult for a qualified technician. It is necessary to measure the output voltages in its secondary circuits, and if they are completely absent, the serviceability of the power switches and rectifier diodes should be checked for a possible breakdown (short circuit).
In case of breakdowns in the secondary circuits of the converter, it can usually work in an emergency mode in a short circuit mode, and with a short circuit in the power elements of the primary circuit, the mains fuse or current sensor in the source of the key is most often cut off.
Mos-Fet power switches used in switching power supplies sometimes fail due to a malfunction of any other elements that can disable it in the key mode, or create an excess of the maximum permissible key parameters. These can be elements supplying a PWM regulator, frequency setting or damper circuits, or elements of negative feedback in the stabilization circuit. PWM controllers, in the absence of visible damage or outright short circuits between the terminals, are checked by replacing them with new ones, or knowingly working properly.
- No picture, sound, all other TV functions are working. When turned on, the image may sometimes appear for a second.
A malfunction is usually in these cases most likely in the backlight units of the display matrix. The reason may be found in a malfunction of the LEDs, in a violation of the contact connections of the LED strips 4-596-427 17Y 32_7020_32_REV01_170316, or in providing their power supply (LED driver).
It is impossible to check the LED bars for a break without disassembling the panel with a multimeter or tester. For these purposes, it is necessary to open all series-connected PN junctions and a voltage of the order of tens of volts is required, and ideally a current source. Having disassembled the panel, it is necessary to check each LED separately. Chinese multimeters tend to light one 3-volt LED in the forward direction. In the case of using dual 6-volt LEDs, the PN junction of its protective zener diode can serve as an indicator of serviceability. In faulty LEDs, the zener diode will either be cut off, or pierced in the K / Z.
- The TV does not turn on, does not respond to the remote control. The indicator blinks or signals the standby mode.
Repair or diagnostics of the 1-981-541-23 motherboard should begin with checking the stabilizers and power converters required to power the microcircuits and matrix. If necessary, you should update or replace the software (software). In some cases, to repair the MB (SSB) board, it may be necessary to replace the chips - CPU: MEDIATEK with new or known good ones. In cases where BGA technologies are used, defects are usually localized by heating.
Before replacing the DE251ZP tuner, if there is no tuning to the channels, you must first check the software and supply voltage at its outputs. It is also necessary to make sure that the tuner and processor can exchange data via the I2C bus
Owners and users of the SONY KDL-32WE613 TV should remember that self-repair without special knowledge, skills and qualifications can be fraught with negative consequences that can lead to complete non-repairability of the device!
