I recently repaired a Skyworth 42L05HF LCD TV that had some intermittent issues. The TV would sometimes boot up but then display a black screen with sound, and occasionally it would work normally for a day. After checking the power supply voltage and confirming it was stable, I noticed that the backlight drive circuit used a separate small board module, and the inverter output didn't show any problems. Based on these observations, I suspected the issue was with the small board itself. Upon inspecting the board, I found that one of the capacitors, C4, was cracked. I replaced it with a 0.1µF capacitor, and after testing, the fault was resolved. The TV now works reliably without any issues. Below are the repair photos showing the process and the components involved:
Radiators in this case are manufactured with Stainless steel (SS304, SS316 and SS316L).
These radiators are manufactured with both 1mm CRCA sheet and 1.2 mm CRCA sheet as required and centre distance varying from 600 mm to 4000 mm. Stainless steel radiators can be offered with and without paint.
Through the method, the stainless steel plate type radiator for the transformer is simple in structure, free of complex treatment process on the surface of the radiator, not prone to oxidizing and corroding, long in service life, and high in welding strength.
