Sometimes it turns on, then it doesn't turn on again, only with the panel LED on, if you remove the cable from the socket it won't work again D06 in4148 that feeds pins 13 and 43 of the micro controller. Just remove it and leave it without it, the voltage is 3v and it works great. guinga sdia goias

TV arrived with little contrast, I checked the power supply and found a defect in the d502 power supply close to the r550 Oxidation D502 I put 1n4148 and run to another eletronica miranda

When you plug it into the socket it turns on and the channels work normally if you turn it off on the control or keyboard it turns on but the channels don't work so you have to unplug it again When it doesn't work, turn off the channels, leaving them on standby, if tsound is 1.8 at the u206 output and just remove r10 of 100Ω falcon eletronica
SAMSUNG UN46D7000LG
It doesn't turn on, but it hits the relay. If we disconnect the cable that goes from the power supply to the main, the TV turns on and the LEDs light up. then the main board or tcon is completed. I disconnected the cable from the tcon and the TV turned on, it turns out tcon, but in this case, oddly enough, tsound was bad contact in the flat cable fitting on the tcon, it actually turned off the TV as it moved in this fitting, I cleaned it with propyl isodine and eraser and just ran for a hug.

PHILCO PH400
Low sound, but everything works. You can barely hear it, even with the volume turned up to maximum. In this case it was IC8, an 8-terminal IC, close to the DVD motor connections Replace the ic8: f16-100 hip Romildo Behrend Schwartz
PHILCO PH400
The device doesn't turn on, it just turns blue on the front, on the volume button, but it doesn't activate anything. It was discovered that it was a diode, which is on the IC side of the DVD motor drive, wsound tsound are 3 in the middle of 2 larger transistors: d33 Replace the d33, even if it is good in terms of measurement Romildo Behrend Schwartz
PHILCO PH400
The blue volume LED keeps flashing and the device does not turn on. the 5v and -21 power supply is oscillating, below what it should be. After much research, it was found that the 33nf capacitor cb8 was responsible. Replace for another good one, even if it doesn't show a defect. It is close to the photo coupler and the DVD motor connections. Romildo Behrend Schwartz
