    LG LED 47LS4500 problems

    Hi I'm new and was wondering if anyone could help me with an issue with my television.
    My tv is giving me two issues. Firstly when I turn it on, it takes a while for it to bring up a picture. Then when the picture comes up there is no sound. I have to turn it off and on numerous times to get the sound to work. The other problem is that occasionally during the times of turning it off and on, the tv will stop working completely. The little red light will turn off like it does when the tv is on, but there is no backlight on the tv and it also will not function. This requires me to unplug the tv and plug it back in to reset it. Any help would be appreciated. Looks like the tv has a main board and power supply board. I could switch one of those out, but it would be expensive if I'm not sure which one to change.
    Any help is appreciated.

    -Kevin

          This tv is not a smart tv. Does it still use firmware?

                      Well I installed the latest version of firmware, but that had no effect. What is service account flash that was recommended and where would I go about getting it?

                          Main Bd issue......BGA IC could have cold solder joints.....Look for other cold solder joints on the Main Bd, as well.....

                              Hello friends, I just received this equipment, it has a strange hum on the board. The computer works fine, outputs an image and starts Windows. But the problem is when charging the battery, a constant loop to charge. In short, it never charges the battery. When the charger is connected, the stability of the CPU is stressed and it seems that the coils make that electrical sound louder. This board is modern and I don't have a schematic. I have checked with a microscope and the pcb is completely new. Has anyone had this happen to them before? defect in driver ic?...

                              Hello to the forum.

                              My name is Christos, I am new to the forum here and i am posting from Greece.

                              So i have this old German sound card from Marian, called Trace Alpha. To be exact i have 2 of them and i use them professionally for my small FM radio station here. The first one works like a charm, but the second one does not work at all.

                              To be more specific in the same exact pc with windows 7 (i even tried 32bit) the one works while the other doesn't.

                              So i tried asking for a schematic from the company and they would not give me one. Instead they...
