Howto repair LG MMD62 ONLY 1 CHANNEL GIVE SOUND FOR RADIO, NO DVD SOUND ANDIF RADIO SET WILL SOUNDTHEN GRADUALLY FADE AND NO MORE SOUND, WHAT 4ARTS AND HOWTO EST THE COMPONENTS

[@idolservicetech955]

In that case the unit have several problems. To tell you the truth LG MD62 is not repairable unit unless you are going to replace the mainboard, the boards are double sided, it uses digital audio too which is hard to trace the cause of the problem. I don't think so if you can follow the steps in troubleshooting. In my video the problem is no sound both left and right and it is just very easy to replace the audio ic, still trial an error is made to solve the problem.

Hi good pm sir may 5.1 LG problem is when you power on and tune in on fm radio there's an audio out after 5-10minutes the audio out was shut down how can I fex the problem

[@idolservicetech955]

There's a defective part/s that once getting hot after it was turning on, the defect comes in causing the audio to disappear. Most likely voltage regulator/s.

No display, no sound of dvd, optical lense good, tuner good sound, aux sound good, problem NO DISPLAY, NOSOUND DVD WHEN PLAYING

[@idolservicetech955]

Check the supply voltage for the display may be bulging filter capacitor or open resistor supplying the display. If no sound trace the audio signal output coming from the mcu before reaching the audio ic if the signal is there then you have a bad audio ic, but if no audio signal coming from the mcu then the problem is on the mcu.

[@idolservicetech955]

@@pudenciojr.camposp.4773 I will just make a video for you how to check voltage for the display of LG MDD62. At first I am also struggling in repairing this unit due to the double sided board that was being used, the space and you can't test the unit if some boards are not connected. That is why I am telling you that this unit is not repairable. The only easy way here is to replace the audio ic because it is just in the corner like what I did. But maybe for other problems of this unit I can no longer repair it.
