Hitachi TV burnt led
colleague: apart from the testers q, listed below you can try to measure it with the digital voltmeter ... you put the selector x diodes you are looking for a led on the strip q, it is in good condition ... then you look for the positive terminal of the led and the terminal negative ... to the negative terminal of the led you connect the black tip and to the positive terminal you connect the red tip ... if it turns on it is 3v ... if it does not turn on it can be 6v ... if there are doubts you try the first leak ... it is very easy to change the LEDs on that led tv ... I just have to be very careful when disassembling the panel ... not flexing ... it can damage ... greetings!
Hello colleague: if you refer to the first tester it can be a source of 500mp ... or also of 300mp ... in the second tester this is connected directly to the electrical network ... but (EYE) ... the tester that , this in the figure is for an electrical network of 110vac ... but if you have a network of 220vac you must change the electrolytic of 10mfx250v x one of 10mfx400v ... and you must change the R of 10kohm x one of 22kohm x 4w. ... and install a 1A fuse between the mains and the entrance to the diode bridge ... comment if you understood what was suggested .... greetings!
