Re: HP S5053 55" LCD TV monitor black screen with sound
Is the backlight on? (should see a dim glow) or an image with a flashlight?
Or that's the model code for a Samsung? and therefore that would be a plasma, making the question irrelevant (of course there could still be a glow). -

Ok we are probably looking at a problem with Y section of the TV.
Got a multimeter?
Test outputs of the power supply just to confirm voltages are as they should be and then check the fuses on the Y sustain board and x sustain too.Comment

Re: HP S5053 55" LCD TV monitor black screen with sound

Re: HP S5053 55" LCD TV monitor black screen with sound
What do you mean by power inverter?
You have the main power supply which then goes into your sustain boards.
There is no inverter board if that's what you meant; those are on LCDs....if HPS5053 is the right model code then this is a plasma.
Pictures are very helpful if you can. (Using manage attachments feature)Last edited by drpj23; 11-30-2012, 06:14 PM.Comment

Hello, I'm working on a new deskmod pc project and have a problem with my monitor, an AOC U34G3XM, well, I may have bricked it.
The monitor was dismanteled and the separate parts parts integrated in the desk. the screen panel alone is on the upper part, and main board/video board + power board on the back of the desk (not enough place on the cover to fit it)
At first everything was working smoothly, then I decided to change the connexion between the video board and the screen for a longer one. Still working fine
During another reassembly, I made a mistake, and... -
I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.
I ordered a supposedly ‘new' Tcon board this time, and... -
I have a 2019 75" x950g, and while playing a movie, the screen suddenly went dark in a weird way, where it faded towards one corner into being fully black. Now the TV turns on, and the backlight comes on, but there is nothing displayed except black. Sound still comes through the TV speakers, and i have tried doing a hard reset using the volume - and power buttons while plugging the display back in, but it did not fix it. I can confirm that pressing buttons on my remote is still doing "something" because I'm hearing sound still, even though the screen is black.

Hello,
YouTube video of the problem encountered: https://youtube.com/shorts/q7TLNv36LUo
I am a pro and I have a problem that I have never seen despite my 7.5 years of experience on my own and my thousands of repairs, on a customer's Dell G3 15 3500.
On this PC I have already changed the complete palmrest because the keyboard was no longer working properly.
I also changed the screen because the PC fell and the screen was broken.
I changed the battery with a new and original battery.
I also had corrosion/oxidation on the... -
Good morning.
I have a problem with my LG Smart 43UF640V TV. It starts, the backlight comes on but nothing is displayed on the screen and there is no sound.
I thought it was a TCon problem and ran various tests. If I disconnect one or the other of the cables from the tcon to the panel then the screen is white on the side where the cable is disconnected and black on the other side. If the two cables are disconnected the screen is completely black.
In the 4 configurations I measure exactly the same voltages on the tcon card (model V15 43UHD TM120 Ver0.4) :
HVDD : 7,28...
