Re: Vizio VX552XVT Inverter problem?
This is exactly the problem the backlight. LEDs are often overheated as a result of maximum brightness. This work is not so much difficult as demanding as to the accuracy. Be sure to use low-temperature solder for soldering the LEDs. But having no experience of such work is better not to make.Leave a comment:

Re: Vizio VX552XVT Inverter problem?
Это именно та проблема, подсветки. Светодиоды часто перегретый в результате максимальной яркости. Эта работа является не столько сложно, как требуют в отношении точности. Обязательно используйте низкотемпературного припоя для пайки светодиодов. Но не имея опыта такой работы лучше не делать.Leave a comment:
