TV does not turn on, standby LED flashes 4x indicating balancer error. | Check inverter board ssl460el-s02. power supply on 180u x 50v capacitors at double. Defective TV is at 23v and after it works it switches to 36v. If it is not doubling to 36v, a possible defect on the inverter board. | In my case, I replaced the ssl460el-s02 inverter board and the defect was resolved. | rafaelmoraes99 |

The LEDs go out, the backlight goes out after turning on the TV | This "fdp" TV is critical for the LED drive circuit. a ruler was defective, I bought the kit and the rulers they sent me didn't fit the tracks next to the ruler connectors, that is, the central pin is not connected to the side pin and when placing the rulers, the TV turns on and doesn't even light the backlight. Well, I redid the connection of the tracks on the rulers themselves, then the TV turned on the LEDs for seconds and went out... then the scare came, but as all the LEDs on the rulers lit up perfectly, I already concluded that the rulers were perfect (LEDs of 3 volts). I set out to discover a fault on the main board. After seeing the tips sound on the website, I saw that it was a tough nut to crack, the tips from friends didn't work in my case. I wetted the drive circuit near the c.i(up4) tps61196 with isopropyl, the TV kept the LEDs on, but as soon as the alcohol dried it turned off again. I took the schematic and analyzed the vsen(ovp) line and tsound was 3.02v perfectly, but as I put the multimeter to check this voltage of 3.02v, the TV no longer turned off the LEDs, that is, if I removed the multimeter the TV turned off the LEDs, the multimeter kept the LEDs on. so this internal resistance of the digital multimeter has anΩic value, on the 20 v dc scale it was close to 200 kΩ, as I measured with another multimeter from the positive to the negative of the cables of this test multimeter and the idea came to me that I should put another one in parallel. 200k resistor with this rp57 position smd resistor and the TV returned to normal, the protection was probably wrong... for me it worked, I hope it helps you. | Put a 200Ω resistor in parallel on the rp 57 of 200 kΩ as well. | MIGUELTV |
