ERISSON 19LES62
General repair guidelines for TV LCD LED
TV ERISSON 19LES62, like many other electronic devices, it is advisable to start repairing by inspecting all external and internal elements. Visible damage to the elements can sometimes indicate the direction of the search for the defect even before the necessary measurements. If ring cracks are detected in the soldering of the terminals of the elements or dangling connecting tracks, swollen capacitors or charred resistors - all this can be characteristic signs of the causes or consequences of an already known typical malfunction.
Malfunctions of the power module can be expressed in different ways, for example, ERISSON 19LES62 does not turn on at all and the control lamps on its front panel do not light up and do not blink, there are no signs of operability. It should be noted that with the same external manifestations, the processor power regulator (converter) may be faulty. 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.
If a breakdown of the power switch is detected, it should be remembered that in a switching power supply (IIP) it does not fail by itself without any reasons that should be sought by checking other elements of the primary circuit - electrolytic capacitors, a PWM controller, which can only be checked replacement, as well as other semiconductor elements (diodes, transistors, zener diodes).
In cases where the ERISSON 19LES62 TV has lost its image, and the sound is there and all other functions are operational, there is a possibility of a malfunction of the LED driver (converter for powering the backlight LEDs of the SEL185V3-SD0X 720p HD panel). When you turn on the TV, the image may appear briefly and disappear immediately. It must be borne in mind that with such manifestations the LEDs themselves also fail.
Often in the absence of backlighting, disassembling the panel is required. It is necessary to check the serviceability of the transitions of the LEDs, as well as the reliability of the contact connections in the rulers and connectors.
When diagnosing, it is necessary to take into account that it is impossible to check the open in the chain of LED lines without disassembling the panels using a tester or multimeter. To open all PN junctions connected in series, a voltage of the order of several tens of volts is required, and ideally, a current source.
Diagnostics and repair of the motherboard 5800-A8M260-0020 is carried out by checking the performance of the stabilizers or power converters of the module chips. In some cases, a software update is required.
Complex repair of MB (SSB) is possible only in the conditions of a service center with the necessary equipment. Checking or replacing CPU elements: MST6E181VS-LF-Z1, SPI: FLASH MX25L3206E requires the necessary training and professional skills to repair modules at the component level. Problems associated with the use of BGA soldering technologies can be diagnosed by warming up.
In cases where there is no tuning to the local television channels, make sure that there are supply voltages at the terminals of the HFT2-8F / 115CW tuner.
Once again, remind users! Attempts to self-repair a TV ERISSON 19LES62 without the appropriate qualifications and experience can lead to its complete unrepairability!

ERISSON 19LES62 TV with a SEL185V3-SD0X LCD display, 19 "(48 cm) diagonal size in 16: 9 format. The LED panel of this TV has LED backlighting - Edge LED. You can view high quality images 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 analog systems PAL, SECAM, NTSC. Graphic processing and digital signal generation occurs in standards 480i, 480p, 576i, 576p, 720p, 1080i. Stereo audio is implemented two built-in speakers. The audio processing system NICAM STEREO is used.
The external interface (communication with other devices) is supported by standard input and output connectors: antenna input (RF), AV. 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.
Overall dimensions: With stand 769x536x196 mm, Without stand 769x485x50 mm.
Attention! The panel of SEL185V3-SD0X 720p HD ERISSON 19LES62 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.
