General repair guidelines for TV LCD LED
Possible manifestations of defects
- The SHARP LC-24CHG5112E TV does not turn on, does not respond to the remote control and the control panel buttons, the indicators do not light or flash.
In such cases, the main power source - the AC / DC voltage converter, which is combined with the MainBoard TP.MS3463S.PA511 board, may turn out to be faulty. It is necessary to verify the presence of its output voltages and, if they are completely absent, check the power switches (TO-252) and rectifier diodes for a probable short circuit.
In case of any breakdowns in the secondary circuits, the converter can operate in emergency short circuit mode, and during short circuit in the power elements of the primary circuit, the mains fuse or the current sensor at the source of the key more often breaks.
Mos-Fet keys used in switching power supplies usually fail due to a malfunction of other elements that can put it out of operation in key mode or provoke the excess of maximum current or voltage values. These can be circuits supplying the PWM controller, damping or frequency-setting circuits, or elements of OOS (negative feedback) in the stabilization circuit. PWM controllers (PWM) PWM SOT23-6, in the absence of external damage and short circuit between the terminals, are checked by replacing with obviously good ones.
- There is no image, but there is sound, it reacts to the remote control. Or the image appears when you turn on and immediately disappears
In some of these cases, the malfunction is caused by a lack of backlighting on the display. The reason can be both in the power of the LEDs, in their serviceability (breakdown or breakage), as well as in the violation of the contact connections of the LED strips.
When trying to detect a break in the LED lines, it should be taken into account that it is difficult to do this without disassembling the panel. For example, a current source is needed to open PN junctions connected in series.
- The indicator on the front panel blinks, the TV does not turn on in the operating mode, it does not respond to the remote control.
Repair or diagnostics of the TP.MS3463S.PA511 motherboard should begin by checking the stabilizers and power converters needed to power the microcircuit and matrix. If necessary, update or replace the software (software).
Before replacing the tuner CDT-9NT372-RF01, if there is no tuning for the channels, you must first check the software and the supply voltage at its terminals. It is also necessary to make sure that the tuner and processor can exchange data via the I2C bus
Attention to users! Self-repair of the SHARP LC-24CHG5112E TV without the appropriate qualifications and the necessary experience can lead to its complete non-repairability!
