Question about Proscan Televison & Video
Hello, I have an issue i was hoping you could help me resolve. I have a proscan television model number PLDED5066A - E, its a 50'' led tv. The screen went black but everything else was still functioning. I did some research and came to the conclusion that the backlight inverters were bad. On that paticular model they are located on the main boaed, after receiving a new part and having it installed the tv still has the same issue. Do you have any thoughts on the situation?
Check whether the control voltage comes to the inverter section cirlcuit at its power board; from the main board. There is a control voltage that controls the light intensity; as well as start, of the inverter section circuit at the main power regulator [SMPS]. It should come from the main board. It this voltage is absent, the main board is faulty. Check whether it is present or not. It will be best to contact any service technician in this case. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

Most of the possibility is that one of the LED diode located on the back lights assembly is bad (opened up), or the main board Backlights-on control section is bad.
