General repair guidelines for TV LCD LED
Possible manifestations of defects
- The MYSTERY MTV-2410LW TV does not turn on and does not show any signs of operability at all. There is no reaction to either the remote control or the front panel control buttons.
Most often, with such manifestations, the main adapter power module is found to be faulty.
This TV model is equipped with an external power adapter type Adapter 12V 4A, which the owner can purchase independently, and repairing it may not always be advisable, however, sometimes there is some reason to open it and eliminate simple typical defects typical of IIPS. It is necessary to measure its output voltages and, if they are absent, to check for short-circuit probabilities in the converters, power switches and rectifier diodes.
In case of diode breakdowns in the secondary circuits, the converter can operate in emergency short-circuit mode without output voltages, and during short circuit in the power elements of the primary circuit, the mains fuse and / or current sensor at the source of the key usually breaks.
The breakdown of Mos-Fet keys used in pulsed sources is often caused by malfunctions of other elements, for example, power supply, frequency-setting, damper ... as well as elements of the Negative Stabilization Feedback. The PWM chip can also cause a malfunction of the power switch of the converter and is checked by replacement.
- There is no image, there is sound, it responds to the remote control. Or the image may appear for a second when turned on and immediately disappears.
In such cases, the most likely malfunction of the LED backlight elements. The reason for this may be a break in the LED circuit, or a problem in stabilizing their power supply.
To check the LED strips, to open all the transitions of the LEDs, several tens of volts or more are needed, it is best to use a current source for such purposes. The breakage of several PN junctions connected in series cannot be detected with a multimeter or tester. In such cases, it is necessary to open the panel and check each LED. If your multimeter cannot open the LED transitions in forward bias, you can sometimes detect the presence of a PN junction of the protective zener diode by connecting the probes in the opposite direction. If the zener diode is broken or broken in short-circuit, then the LED is faulty and needs to be replaced.
- The TV does not turn on, the indicator indicates standby or operating mode, or blinks.
Repair or diagnostics of the JUG7.820.807 motherboard should begin by checking the stabilizers and power converters needed to power the chips and matrix. If necessary, update or replace the software (software). Sophisticated MB board repair (SSB) is in some cases possible and practiced by repairmen. To do this, check and, if necessary, replace the CPU elements: TSUMV26KU-LF, SPI Flash: EN25F40, SOUND: УD1517P. BGA chip malfunctions are usually easy to detect by warming up.
If there is no reception of television channels, but the TV is working properly from external devices, first of all you need to check the power supply of the tuner CDT-3FC2I2-00 and update the software. The pulses from the I2C bus must be controlled with an oscilloscope.
Once again, remind users! Attempts to self-repair a TV MYSTERY MTV-2410LW without the appropriate qualifications and necessary experience can lead to its complete non-repairability!
