General recommendations for repairing TV LCD
Possible malfunctions
- ERISSON 15LS01 does not turn on and does not show any signs of operability at all. Does not blink indicators and does not respond to control buttons.
Failure in such cases should begin to look in the adapter power supply circuits.
This model of TV is equipped with an external power adapter adapter type 12V, which the owner can purchase independently, and repairing it may not always be advisable, however, sometimes it makes sense to open it and eliminate simple typical defects typical of IPS. 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 a short circuit.
In case of breakdowns of semiconductors in the secondary circuits, the converter can usually work abnormally in the short circuit mode, and during short circuit in the power elements of the primary circuit, the mains fuse often breaks.
The breakdown of Mos-Fet keys used in pulsed sources is often caused by malfunctions of other elements, for example, in the power supply circuit of a PWM controller, in frequency-setting or damping circuits, as well as in Negative Stabilization Feedback. PWM microcircuits are usually checked by replacement with new ones, or obviously working.
- There is no image, but there is sound, it reacts to the remote control. Or the image appears when you turn it on and immediately disappears
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 indicator on the front panel blinks, the TV does not turn on in the operating mode, it does not respond to the remote control.
Repair or diagnostics of the PA20154 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).
Before changing the tuner TDQ-6F6 / W126D, if it is not possible to tune to television channels, make sure that there are supply voltages that need to be measured on the corresponding terminals of the tuner and check the software for correctness. The pulses of the data exchange of the tuner with the processor can be controlled by an oscilloscope
Once again, remind users! Attempts to repair the TV ERISSON 15LS01 on its own without the appropriate qualifications and necessary experience can lead to its complete unrepairability!
Main features of the ERISSON 15LS01 device:Installed matrix (LCD panel) SVA150XG04TB.
To power the backlight, the inverter PCB-DA207B is used, it is controlled by the PWM controller TL5001C. A transformer SED TNA-DA104 is installed in the inverter converter. As power elements of the inverter, keys of the type P61AF, D1802 (3), 9435GM (8) are used.
To power all internal components of the ERISSON 15LS01 TV, an external adapter type AD055S + 12V, 4A is used.
MainBoard - the main board (motherboard) is a module 5800-A8T84E-01, using 25P20 BD3888FS TDA9681TS TDA15521E / N1C80 HEF4052BT LM317M 4953P TDA1308, DC-DC 1501-50 and others.
The TDQ-6F6 / N126CVA tuner provides TV reception and channel tuning.
