My blaupunkt lcd tv goes on but no picture very faintI have sound


Did it ever work right? How old is it? under warranty?

If the pic is very faint, I suspect the background lamps are burned out.

If the sound is very faint, possibly a power supply problem.

Sound but no image on Hitachi 42pd5000


Two things need to be checked. The ballast board and the T-con board. Shine a flashlight on the screen with the TV on...If you see a faint picture moving, then the T-Con board is OK. The ballast board for the white backlight is bad. If you don't see a faint picture, then the T-con board is bad.

RCA L32HD32D no picture


Most likely you have a bad back lamp. Most times when this occurs, the screen will come on for a second or two then go off. Replacing a back lamp isn't a job for do it your selfers. It will involve completely disassembly of the LCD panel.

My LTV-32w6 westinghouse powers on & has sound but displays black screen with very faint colored vertical lines. It shows like this for about 1min before it goes into standby mode & the blue power...


Depends on what is causing it...

Vertical bands of faint black are generally caused by filtering capacitors and can be found in the power supply or the 5 volt supply or even the Video processing circuit...it is not an easy task to identify the source of Video hum bars.....we also call them Jailbars.

Another problem seen is faint black lines caused by the TV set being in 4:3 mode all the time....right at the edge of where the picture ends and the black pillars begin, we see a faint black line that never goes away and is normally seen with a full screen....

That is actually image retention, but it's caused by the crystals that create the picture becoming polarized or ionized over a very long period of time....and it's not easy to DE-Polarize them !

But there are some theories out on how to do that....
Certain people suggest running the TV overnight with an ALL-WHITE picture and some suggest an ALL BLACK PICTURE...and some suggest alternating between both !!

Now, a black picture is easy to make, you just deactivate the Video Mute (blue screen) and set it to an unused Video INPUT overnight....

About the only way to make a white screen is to use the USB port for pictures and take a very bright outdoor shot of a piece of white paper that hopefully is out of focus too....That would create an all-white picture that you can plug into your TV set overnight....

Now if you decide to try this, deactivate any displays on your TV set...all you do is press the display button until the Video and/or USB input numbers disappear....

Next day , set it back to normal TV and see if it's gone or if it's REDUCED....try it again if needed, or try the exact opposite if you see NO RESULTS....

Have sound but no vision?


When the screen goes black, shine a flashlight on the screen to see if you can see a faint picture. If you can then the ballast board for the backlight is bad. If you can't see a faint picture, then the T-CON board needs replacing. You can get parts from here:

Had a major electric surge and now tv has no picture, but has power to it?


when on black screen, put a flashlight onto screen, if u can see picture, its the capacitors (2), 3.00 in parts, follow the power cord to the board inside, look for capacitors that are bubbled on top,

No picture,no sound,blank


This set is very popular for the capacitors to dry upa and go bad in the main SMPS as well as the switching power supply. If you have no know how on how to test capacitors or solid state electronics please take the set into a repair shop for an estimate
