Turns on, blue LED on, no image (black screen) | 3 defective capacitors c301 25v 820uf and fusistor f301 125v 3a LF (green) | Replace of the 3 mentioned capacitors and fusistor. Be careful, don't forget to replace the fusistor as its function on the board is to protect all spike lines. If it opened it is because the peak exceeded its thermal dissipation capacity, without it the board would have been damaged beyond repair. do not bypass by excluding the fuser from the diagram. | Igor Cruz Brilhantino |

Burning leds | Voltage found on the LEDs, 75v. the expected is 66v. This model uses 3 bars containing 22 3 volt LEDs (each LED). the total sum becomes 22x3=66v. This (66v) is the voltage that the LED set supports. | Remove the resistors (20Ω) r251,252,253,254 and replace the value of r255 to 33Ω. the voltage will drop to 66.7v. | Evando Viana |
