General repair guidelines for TV LCD LED
Repair and diagnostics of any electronic device, in particular ERISSON 32LET30, it is advisable to start with a careful external examination of internal and external elements. Often, by the external signs and nature of the damage to the elements, it becomes possible to draw some conclusions and determine a further algorithm for finding a defect before making the necessary measurements at control points. Swollen electrolytic or cermet capacitors, charred resistors, ring cracks in the soldered terminals of the elements - all this can significantly help the master to determine the causes and consequences of the malfunction of the TV.
In cases where the ERISSON 32LET30 TV does not turn on, does not respond to the remote control and buttons, no indicators on the front panel light up or blink, and there are no sounds and no signs of operability when turning on, the SHL3238F-101S LED DR power supply module is most likely faulty = 24v or there is no processor power on the motherboard (a typical defect of some ERISSON TV models). When diagnosing and repairing the power supply, after replacing the swollen capacitors of the secondary rectifier filters (if any), you must first check the mains fuse. When it is broken, the power elements of transistors and rectifier bridge diodes should be checked for avalanche (thermal) breakdown.
The reasons for the breakdown of the power switch in pulsed power supplies (IIPS) can be different, for example, a malfunction of semiconductor cells or electrolytic capacitors in the stabilization circuits of the primary circuit, as well as a failure in the operation of the PWM controller chip or broken resistors in its bundle.
If there is no image when ERISSON 32LET30 is turned on, or it appears for a second and disappears, but there is sound, most likely there is a malfunction in the backlight LED circuit of the V32D30-CSOT V2 panel, or in their power converter. It is necessary to check the electrolytic capacitors of the filter of the secondary rectifiers in the general power supply unit.
To check the health of the LEDs and contact connections in their power circuit, the panel must be disassembled.
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.
If the motherboard 40-MS8200-MAD2XG is faulty, first of all it is necessary to check all the linear stabilizers or power converters of its chips, and also, if necessary, update the software. Sometimes you can check the health of MB only by replacement.
If it is not possible to replace the MB board (SSB), you need to check the health of its elements - CPU MST6E182VS-LF-Z1, Flash 25Q32. Defective components should be replaced.
If you suspect a malfunction of the tuner 07-380FI5-NFHG, first of all, you need to make sure that there is a supply voltage on the corresponding output of the tuner.
For owners of 32LET30 TVs, we recommend that you contact qualified professionals with work experience for repairs! Self-repair attempts without the appropriate knowledge and skills can lead to serious negative consequences!

Technical description
ERISSON 32LET30 TV with V32D30-CSOT LCD display, 32 "(81 cm) diagonal size in 16: 9 format. The required screen brightness of 400 cd / m² is provided by LED backlighting. Contrast, as the ratio of maximum brightness to minimum, is 1200: 1. Edge LED backlighting is realized in the LED-panel of this TV - Edge LED. You can view images in high quality HD at a resolution of 1366x768 pixels in the standard of graphic decomposition 720p (HD Ready). The input high-frequency or video signal can be processed in an analog system . Ah PAL, SECAM, NTSC Image processing and the formation of a digital signal occurs in the standards 480i, 480p, 576i, 576p, 720p, 1080i Supported multimedia file formats:.. MP3, JPEG Stereo realized by two built-in speakers using audio NICAM STEREO processing system..
The external interface (communication with other devices) is supported by standard input and output connectors: antenna input (RF), VGA, USB, Bluetooth. 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.
The power consumed by the TV in the operating mode from the network is 75 watts.
Overall dimensions: With stand 373x270x120 mm, Without stand 470x315x47 mm.
Attention! The V32D30-CSOT V2 panel of an ERISSON 32LET30 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.
