Renovated a Skyworth 32-inch LCD TV, the red light is on, and the second time cannot be turned on. After disassembling, I found that the output capacitor of the power supply board 5800-PLCD26-01 has multiple drum kits, and I think the problem is very simple. After replacing the capacitor of the drum kit, the power output test 5V.12V.24V output is normal, and the DC-DC voltage on the main board 5800-A8K220-0040 is also normal, or can not be turned on twice. It is estimated that the program on the motherboard is messed up when the capacitor is out of capacity. After shutting down, remove U13EN25B64, read the U13 data first, and save it temporarily (in case the original data is not bad, write it back). Empty U13, and then write the data of the machine that was backed up normally. After the calibration is completed, the U13 is soldered. The test machine, and sure enough, Grandpa Mao got it. thanks for watching! I wish all my colleagues a happy new year! A lot of income Mao Grandpa!

Photovoltaic Solar Panel

The photovoltaic solar modules are made of a number of individual silicon solar cells. Different types of solar cells have different efficiency levels, like monocrystalline solar cells and polycrystalline solar cells. To reach as higher efficiency we we can, PERC solar cells with multi-busbar + split cell technologies are used for our solar moduels. Now we reach 21.52% for our pv panels.


Saintish solar panels could be applicated for residential, commercial, industrial and off grid systems. Fully black and silver white panels as well as transparent photovoltaic modules are all accepted in our company.


By installing with Solar Panel, not only reduced carbon footprint, but also reduced your electricity bill and even be paid for the surplus energy generated by feeding into the grid.
