Re: RCA 42" RLDEDV3988-a flickering video
First of all this TV model uses LED backlights so it does not have Inverter board or circuits for the CCFL, so I am not sure what inverter he is talking about.
May be we can start by uploading good clear pictures of all the boards and start from there.

Re: RCA 42" RLDEDV3988-a flickering video
@Bufferb, sadly a lot of folks come here and receive help for their repair and never return to let us know if it was fixed and where the trouble was. As budm said we can narrow down the suspects with some pictures if you would be so kind to post them. The pictures on the original post are far too blurry to be of use, There only appears to be one combined power/ av board. The Op discovered the bad resistor when testing the led power source so the trouble is likely to be very near there.Last edited by Caleb; 03-14-2016, 09:28 AM.Liberating magic smoke one part at a timeComment

Re: RCA 42" RLDEDV3988-a flickering video
Its probably a surface mount resistor on the back side of the power supply. However if he found it while checking for currents, it is very possible that if you check them in circuit it will read a different part so you will have to take them out of circuit and or wait for him to reply about the location.Comment

For the record, same here. Flashing LEDS fixed not by repairing a resister but by replacing LED strip.Comment

I have three identical-spec 820-01700 boards (2.6/32/512), and ALL THREE boards came to us with the same fault, from different sources: The boards don't wake from hibernation with the keyboard or lid, they ONLY wake when you press the power button. I understand this is a very minor issue, but the boards must be fixed!
We will of course begin with the obvious (checking lid signals), but I couldn't help but notice these three boards were all 32GB variants. Has anyone noticed an issue relating to these 32GB boards in particular? I of course don't think it's a RAM issue, but it's bizarre... -
This is from my son’s gaming computer that at first had minor overheating issues when playing a very intense game with it causing the computer to crash or reboot
Then bough a new motherboard and a new computer case that a cooling system in it already installed also brought the cooling system for this video card but now the issue with it is that it randomly rebooted screen goes blank randomly and suddenly video freezing or started with video being there then blank screen and then the video comes back or it just stays blank for a while and then maybe it will come back but it... -
Hello,
The monitor started off showing flickering thin (1 pixel) lines horizontally every say 3mm..
They are black on the right and gradually fade to nothing on the far left.
They start either after 5 mins or up to 2 hours after so annoying for testing.
They flicker continuously very fast! With a slight pause milli-second every second.
Initially I cleaned the LVDS cable and connected to the T-Con and then it worked fine for 3 weeks but not sure if this was just co-incidence.
I tested each half by removing the first the left flex from... -
Good evening, gentlemen.
I have a problem with my monitor. It turns off after a few seconds or flickers. Shining a flashlight on the screen doesn't show any image, so I guess it's not the "2 seconds to dark" I read in the forum.
To turn it back on, I have to press the power button twice. Then after a few seconds it turns off again or flickers. See video.
