REPAIRING AND NOT THROWING AWAY
Richtige Fernseher haben Röhren!
Richtige Fernseher haben Röhren!In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !. These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.Happy repairing!Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.How to use the site:- If you landed here via any Search Engine, you will get what you searched for and you can search more using the search this blog feature provided by Google.

REPAIR / SERVICING TV ERISSON 40LH01
Technical description and composition of the ERISSON 40LH01 TV, type of panel and applicable modules. The composition of the modules.ERISSONModel: 40LH01Chassis / Version: CV028GHPanel: LTA400WS-L03Lamp backlight: 20 Lamp CCFLInverter (backlight): 24V40W2S (HIP0212A)PWM Inverter: DMB8110DMOSFET Inverter: SI4942Power Supply (PSU): MLT090B (P079)MainBoard: CV028GH_MA_V3IC MainBoard: TP2808HQN, IS42S16400D-7TL, MSP3415G 88_V3, MST5151A-LF, SAA5361HL / M1, TPA3002D2, IS62WV2568BLL-55HLTuner: JS-6H2 / 121Specifications 40LH01ERISSON 40LH01General recommendations for repairing TV LCDPossible malfunctions- ERISSON 40LH01 does not turn on, does not respond to buttons and remote control, indicators on the front panel do not light and do not blink.With such manifestations, in some cases, the MLT090B power module is faulty. It is necessary to measure its output voltages, and in case of their absence, check the operability of the power switches of the converters and rectifier diodes for the probability of short circuit.In case of breakdowns of semiconductors in the secondary circuits of any converter, as a rule, it can operate in emergency short-circuit mode without output voltages, and during short circuit in the elements of the primary circuit, the main fuse and, less often, the current sensor at the source of the key are most often cut off.Mos-Fet keys used in switching power supplies usually fail due to a malfunction of other elements that can put it out of operation in key mode or provoke an excess of the maximum current or voltage. These can be circuits supplying the PWM controller, damping or frequency-setting circuits, or elements of OOS (negative feedback) in the stabilization circuit. PWM controllers (PWM), in the absence of external damage and short circuit between the terminals, are checked by replacing with obviously good ones.- There is no image, but there is sound and reaction to the remote control. Or for a second, the image may appear immediately after switching on.These manifestations can be triggered by a power module, or by defects in the inverter, as well as a distortion of the currents in the lamps due to their uneven wear. If all the electrolytic capacitors of the filter according to the inverter power supply are serviceable, you should make sure that the lamps are working, then you need to check the converter keys and the secondary windings of the transformers.If in diagnosing a malfunction, it is necessary to disable the inverter protection, there is a risk of failure of the power elements of the inverter, and special care is required during work, and after they are finished, it is necessary to restore the protection circuits for further safe operation of the TV by the owner in normal mode.- 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 CV028GH_MA_V3 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). In cases of complex repairs of MB (SSB) and in the presence of the necessary skills and equipment, sometimes it may be necessary to replace its chips TP2808HQN, MST5151A-LF, IS42S16400D-7TL, MSP3415G 88_V3, SAA5361HL / M1, TPA3002D2, IS62WV2568BLL-55H6051 and other TVP components. Malfunctions associated with the application of BGA soldering technologies are usually easily diagnosed by the heating method.If a JS-6H2 / 121 tuner is suspected of malfunction, first of all, it is necessary to verify the correctness of the software, as well as the presence of the necessary levels of supply voltages and data exchange pulses with the processor via the I2C bus at the corresponding outputs of the tuner. Attention TV owners! Self-repair attempts by ERISSON 40LH01 are not recommended by the manufacturer and can lead to serious negative consequences!
Main features of the ERISSON 40LH01 device:Installed matrix (LCD-panel) LTA400WS-L03.To power the backlight, an inverter 24V40W2S is used, it is controlled by the PWM controller DMB8110D. As power elements of the inverter, keys of the type SI4942 are used.The formation of the necessary supply voltages for all nodes of the TV ERISSON 40LH01 is carried out by the power module MLT090B, or its analogues.MainBoard - the main board (motherboard) is a CV028GH_MA_V3 module, using TP2808HQN, IS42S16400D-7TL, MSP3415G 88_V3, MST5151A-LF, SAA5361HL / M1, TPA3002D2, IS62WV2568BLL-55H microcircuits.The JS-6H2 / 121 tuner provides TV reception and channel tuning.Additional technical information about the panel:Brand: SAMSUNGModel: LTA400WS-L03Type: a-Si TFT-LCD, PanelDiagonal size: 40 inchResolution: 1366x768, WXGADisplay Mode: S-PVA, Normally Black, TransmissiveActive Area: 885.168x497.664 mmSurface: Antiglare (Haze 40%), Hard coating (3H)Brightness: 500 cd / m²Contrast Ratio: 1000: 1Display Colors: 16.7M (8-bit), CIE1931 72%Response Time: 10/6 (Tr / Td); 8 (G to G)Frequency: 60HzLamp Type: 20 pcs CCFL Embedded (Inverter)Signal Interface: LVDS (1 ch, 8-bit), 30 pinsVoltage: 5.0VBrand: ERISSON, Model: 40LH01.Shortly from the TV: LCD, diagonal 40 "(102 cm), there is a PIP.The composition uses MainBoard CV028GH_MA_V3 and LCD-panel LTA400WS-L03.Power Supply Unit (PSU) MLT090B (P079) Power Supply.TV ERISSON 40LH01 with LCD display LTA400WS-L03, diagonal size 40 "(102 cm) in 16: 9 format. Screen brightness of 500 cd / m² is ensured by backlighting with CCFL (EEFL) fluorescent lamps. Contrast, as the ratio of maximum brightness to minimum, is 1200: 1. The input high-frequency or video signal can be processed in analogue systems PAL, SECAM, NTSC. Graphic processing and digital signal generation takes place in the standards 480i, 480p, 576i, 576p, 720p, 1080i.The power of the sound speaker system 20 W (2x10 W) provide two 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), RGB, VGA. 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, 1280x1024, 1360x768.Dimensions: With stand 550x443x175 mm, Without stand 550x411x82 mm.Attention! The LTA400WS-L03 panel of an ERISSON 40LH01 LCD TV is its most expensive component.Avoid hitting the glass and exerting pressure on the screen to avoid permanent damage to the LCD panel!
