SOURCE: sound works but no picture. black screen

I've had the same problem. Usually, if I turn the TV off and then back on again, it's fine.

I would use the warranty for this problem. The part that need to be replaced can be somewhat expensive.
With the credit card statement, you can use that as a receipt.

SOURCE: LG 50inch Plasma received loud sound then went black

My friend's LG 50" plasma tv has the same problem and it cannot light up. The picture and sound are working fine. But the brightness is too low. It is purchased 2006 too and out of warranty. So I opeend up and found 9 capacitors 3300uF 10V on the power module at the middle of TV are popped. I am planing to replace all of them. They are available at digikey.com. I think this model's power module has design flaw. The cap rating may to low. 10V? Stay tune to see what happen after I change the all the caps.

I have an Alba LCD 19 inch. Today as i was watching a movie the screen went black but the sound was fine.However if i put a flashlight in the screen i can still see faint image. Can u please help me


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should trouble shoot. Contact any service technician. The circuit will differ with models and versions.

We will get a black screen but still have sound.


Sounds like a main board that controls everything on the screen and then some.

Since a LCD do the flashlight test (what I call it) : darken the room as much as possible and with a flashlight and the set on look closely at the screen, see a very very faint image of the picture or not?

Most likely you have a fault in the back light circuit. To verify this, turn on the set, when the screen goes black, take a bright flashlight and shine it on the screen. It may be easier to dim the lights in the room so that you can see the faint image on the screen. If you see the faint image, you indeed have a back light problem. You will need to get a diagnoses performed on the set to track down the problem

Sony bravia black screen audio ok


It is a LCD set and if sound get it in a very dark room and with a flashlight and the set on look to see if you see a very faint image on the screen.

Almost all these sets use a back light system for brightness---an inverter of some type to power the lights---either the back light is bad or the voltage for it is not present or being turned on.

I HAVE A SVA 37in HD VR3718W tv, that just went out. we were watching it and all of a sudden it just went black like someone turned it off but you could still hear the sound..what do i need to fix it and...


Without testing the tv all i can say is that, from your description, it can be only the T-con board or the ballast for the backlighting. Take a flashlight and point it at the screen from up close - if you see the image there it's the ballast, if you don't the t-con.
These are the boards

Sound but no vision, black screen


It's either the backlight lamp or backlight inverter is busted due to a power failure or fluctuation. Here's how to determine which is which:
  1. Grab a flashlight.
  2. Turn on the TV.
  3. Shine the flashlight onto the screen.
  4. If you cannot see any display even a faint one, the backlight inverter is dead, else the backlight lamps are busted.
  5. Replace which ever is the culprit.
