General repair guidelines for TV LCD LED
Possible malfunctions
- The TOSHIBA 32E2533D TV does not turn on. There are no signs of operability. The indicators on the front panel do not light up and do not blink, the TV does not respond to the control buttons.
In some of these cases, a malfunction is detected in the UE-3640-1C power supply module. Then we recommend that you measure its output voltages and, if they are absent, you should check the health of the power switches and rectifier diodes of the converters for a probable short circuit.
In case of breakdowns in the secondary circuits, the converter can operate in a short circuit mode, and during a short circuit in the elements of the primary circuit, the mains fuse usually breaks.
Breakdown of power switches (MosFet) in pulsed sources is sometimes caused by malfunctions of other circuit elements, for example, in circuits supplying a PWM controller, frequency-setting or damper ones, as well as in negative feedback circuits (OOS) of stabilization. PWM controllers (PWM), if they do not have visible damage to the chassis and open short circuit between the terminals, are usually checked by replacement.
- There is no image, but there is sound and all the other functions of the TV work. The image sometimes for a second appears immediately after turning on and disappears.
A malfunction is usually most likely in these cases at the backlight nodes of the display matrix. Usually the cause of the malfunction is in the breakage of the LEDs, or in the connectors of the LED strips, but sometimes the LED driver also turns out to be faulty.
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 TV does not enter the operating mode, does not respond to the remote control. The indicator on the front panel lights constantly or blinks.
Repair or diagnostics of the SR050D 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). If it is not possible to replace the MB board (SSB), you need to check the health of its elements - CPU: MSD8831RM2, SPI Flash: W25Q16DVSSIG. Defective components should be replaced.
Before replacing the ST42CS-2-E tuner, 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
It should be remembered! Attempts to independently repair the TOSHIBA 32E2533D TV, in the absence of the necessary qualifications and experience, are categorically not recommended and are fraught with negative consequences, up to the complete non-repairability of the device!

Installed matrix (LED-panel) U320DH01.
The matrix control uses the Timing Controller (T-CON) E15063094V-0.
To power the backlight LEDs, a converter is used, combined with a power supply.
The formation of the necessary supply voltages for all nodes of the TOSHIBA 32E2533D TV is carried out by the power module UE-3640-1C, or its analogues.
MainBoard - the main board (motherboard) is an SR050D module using CPU chips: MSD8831RM2, SPI Flash: W25Q16DVSSIG and others.
The ST42CS-2-E tuner provides television reception and channel tuning.
TOSHIBA 32E2533DG LED TV with U320DH01 LCD, 32 "(81 cm) diagonal size in 16: 9 format. The required screen brightness of 300 cd / m² is provided by LED backlighting. The ratio of maximum brightness to minimum (contrast) is 5000: 1 Dynamic contrast ratio of 12500: 1 is achieved by special control of the LEDs operation.This model uses side LED backlighting from Edge LEDs. You can view images in high quality HD at a resolution of 1366x768 pixels in the standard of graphic decomposition 720p (HD Ready). Audio or video signal can be processed in analogue systems PAL, SECAM, NTSC. Graphic processing and digital signal generation occurs in standards 480i, 480p, 576i, 576p, 720p, 1080i, 1080p, 2160p. Supported media file formats: MP3, WMA, MPEG4 , JPEG.
The power of the speaker system of sound 14 W (2x7 W) provide two speakers. It uses a NICAM stereo signal processing system and Sound Surround.
The external interface (communication with other devices) is supported by standard input and output connectors: antenna input (RF), AV, component, HDMI x2, USB. An output for connecting headphones is provided. To connect a computer or laptop to this TV model, a VGA (D-Sub 15) connector is used on the TV case, this interface supports resolutions: 640x480, 800x600, 1024x768, 1360x768.
A digital tuner is capable of receiving television channels in the DVB-T MPEG4, DVB-C standards.
The power consumed by the TV in the operating mode from the network is 51 watts.
Overall dimensions: with stand 734x489x180 mm, without stand 734x438x17 mm.
TV mass: with stand: 6.8 kg, without stand: 6.1 kg.
Attention! The U320DH01 panel of the TOSHIBA 32E2533DG LED TV is an expensive and unreliable element.
Avoid any impact on the glass and pressure on the surface of the screen to avoid damage to the LED panel!
It is also unsafe to get liquid on the screen. Sometimes one drop is enough if it flows down the glass onto the cables so that the TV becomes unrepairable.
