According to user response: TCL LCD TV L55V10FBD This machine just started booting sometimes normal sometimes does not boot, then the fault is turned on slower and slower and finally does not boot! Disassemble check found that the power board 12V\24V has no output PFC circuit does not work, search the Internet It is found that the machine has a common problem: it is the leakage of the glue under the three chip resistors in the 7-pin circuit of L6599! So I quickly turned the circuit and found that the three chip resistors had been turned over and soldered to the circuit (previously after repair and repair once), so the three chip resistors were removed and found that one of the 560K was too large to about 1K. The resistor replacement is turned on normally. In order to determine whether it is a problem caused by resistance variable? Or is it a problem caused by leakage of glue on the board? Also re-switch the original chip resistor back to boot normally (for safety reasons or change the chip resistor)!
