General repair instructions for LCD LCD TVs
Possible malfunctions:
- The TELEFUNKEN TF-LED24S13 TV does not turn on and shows no signs of being operable. There is no reaction from the remote control or front panel control buttons.
With such events, in most cases, the power supply module of the adapter is defective.
The external power supply of the adapter is not always repairable, especially since the owner can buy it independently. But in some cases, it makes sense to open it and eliminate the simple defects that are typical of converters in drawn sources. It is necessary to measure its output voltages and, in case of absence, to check the proper functioning of the power switches and rectifier diodes in the converters in order to avoid possible failures.
During thermal failures and semiconductor avalanches in secondary circuits, the converter can generally operate normally in emergency short-circuit mode. There is no output voltage. And in the event of a short circuit in the power elements of the primary circuit, as a general rule, the main fuse blows and less often the current sensor at the key source.
Mos-Fet wrenches used in switch mode power supplies generally fail due to a malfunction of other components that may disable them in key mode or cause an excess of maximum current or voltage. This can be a power supply, damping circuits or OOS stabilizing elements (negative reaction). The reason for the failure of the power switch may be PWM (PWM). It is verified only by replacement with a known product.
- There is no picture, there is sound, he answers the remote control. Or, the image may appear for a second when it is turned on and disappears immediately.
The most likely in these cases is a malfunction of the LED backlight. This may be due to both the power supply of the LEDs, their operating status (failure or breakage) and the violation of the contact connections of the LED strips.
To detect a break in the LED lines without disassembling the panel, a power source is required. It is impossible to open transitions connected in series with a simple multimeter, a voltage of several tens of volts is necessary.
- The front panel indicator light flashes, the TV does not turn on in operating mode, it does not respond to the remote control.
Repair or diagnosis of the 5800-A5M63E-OP10 motherboard should begin by checking the stabilizers and power converters required to power the chips and matrix. If necessary, you must update or replace the software (software). Sophisticated motherboard repair (SSB) is in some cases possible and practiced by repairers. To do this, check and, if necessary, replace the MSD6306PUN, EN25Q32, TPA3110D2, MP3398A (LED driver), ME15N10-G elements. Malfunctions of the BGA chip are generally easy to detect by heating up.
Attention users! Independent repair of a TELEFUNKEN TF-LED24S13 TV without the appropriate qualifications and necessary experience may result in its total non-repairability!
To reduce the backlight current, the total resistance of the resistors relative to the MP3398A ISET pin housing must be increased proportionally. ISET (current parameter) - pin 8 of the SOIC-20 enclosure or pin 6 of the SOIC-16 enclosure.Repair of the main panel
The appearance of the MainBoard 5800-A5M63E-OP10 is shown in the figure below:
5800-A5M63E-OP10
5800-A5M63E-OP10 can be used in TV sets:
ERISSON 24LES68 (720p HD panel 1366x768), ERISSON 19LES68 (V185BJ1-LE1 Rev. C1), TELEFUNKEN TF-LED24S13 (V236BJ1-LE2 Rev. C1 panel).
Main features of the TELEFUNKEN TF-LED24S13 device:
Matrix installed (LED panel) V236BJ1-LE2, rev. C1.
Matrix control uses the synchronization controller (T-CON) V236BJ1-XCE1.
To power the LEDs in the backlight, a converter is used, associated with the 5800-A5M63E-0P10 main board, controlled by the MP3398A PWM controller.
To power all the internal components of the TELEFUNKEN TF-LED24S13 TV, an external adapter source is used.
MainBoard - the motherboard (motherboard) is a 5800-A5M63E-0P10 module using the microchips MSD6306PUN, EN25Q32, TPA3110D2, MP3398A (LED driver), ME15N10-G and others.
