50" proscan led tv new main board but still same issue....

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.

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.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main digital board.

50 in proscan led tv powers on then has black screen but can see screen work with flashlight


Your backlighting is no longer working.
With a LED TV it's an array of LED's that light it, in an LCD TV it's fluorescent bulbs that do the backlighting.
There's a chance it's the power supply board that's bad, unfortunately, it could also be the backlighting itself.
You'll need an expert to look at it to make that determination.
If you don't know Electronics, don't open it up yourself! There are hazardous voltages even in flat screen TVs. The hazardous voltages are there even when the unit is unplugged!

My Proscan led TV (PLDED3273A) is switching color from red, blue, green, white, and black.


Just do a hard reset to this set and check. To make it a hard reset, unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If this do not help you, the main board to your TV is faulty. Contact any service technician. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy.

When i turn proscan tv on it automatically turns off(just turn on for less than secon


OK I Have a 40" Proscan 40LD45Q
had the power problem when you turn it on it would flash and then cut off again.
after checking I found that the transistor on the power board was bad.
Its one of the 2N4401 transistors found on the cold side in between the
cluster of resistors and and mosfet heat sink. kind of hard to get too
but replaced it and tv works great now.. $1.19 at radio shack for the part.
Hope this Helps ..
