No video on Samsung PN51D440A5DXZA TV

by DTros / June 10, 2014 1:23 AM PDT

My Samsung 2011 Plasma TV Model #PN51D440A5DXZA has no picture but does have sound. It was working fine prior to installing the Chromecast device.
I installed Chromecast on the HDMI 2 input and used the USB port on the side of the TV. Chromecast was working fine then shortly after, the TV screen went black and video never came back on the TV. I removed the Chromecast device and reset the TV to factory settings but no video. I tried using the other inputs on the TV but still have the same issue - no video but do have audio.
I worked this through the Chromecast forum but no luck in getting the TV video back in operation.
I also opened a support case with Samsung but they referred me to a local service center so I wanted to check with this forum to see if any of you had some ideas or could let me know which order of the internal TV circuit boards I could start to replace.
Many Thanks, David.

You did the usual.

My bet is that a tech will have to diagnose it next.

Can you reveal if any on screen menu shows up?

Hi Bob,
There's no on screen display at all. The HDMI port did switch back to HDMI 1 input as I can hear the audio from the Dish Network channel but no video.

So it showed HDMI 1 on screen?

If it's dead be aware a tech must see it unless you are TV/electronics tech/engineer. I design electronics so I'm well aware of the lethal voltages inside so with a stern warning I suggest you grab this PDF.

That's quite a find and unusual to find on the web so it's GOLD. But then again I can't know if you know about working with lethal voltages or which end of a solder iron to pick up.

No Video - HDMI 1

Hi Bob,
There was no video on the screen from the HDMI 1 input - there was only audio.
Thanks for the link to that document. I am somewhat familiar with electronic circuits - haven't designed any in a long time and used to work on TVs' (back in the vacuum tube days).
I was hoping that someone might have seen this before and could tell me which board(s) is the most likely suspect.

I guess I was unclear.

But first, such failures are too numerous and often the owner has two choices. Repair or replace so there is no question others have seen this.

However I had hope to read you saw "HDMI 1" text flash on the screen but without the video from the input. If any menu/text showed I have a procedure to try but no reason to do that now.

Finally, I would never guess which board without measuring the voltages noted in the document I shared. Not one tech I know would either.

Is there a command line on this TV?

If so, enter xrandr and see if you get any information output. If so, then you might be able to get help for this from a Linux community.

Hello James,
I have not run across anything regarding command line access.

The Samsung RF23M8090SG

One of the best French door fridges we've tested

A good-looking fridge with useful features like an auto-filling water pitcher and a temperature-adjustable "FlexZone" drawer. It was a near-flawless performer in our cooling tests.
