Lcd TV display is dark

I have an 26" lcd tv, the display is dark across the whole screen even though both brightness and contrat are at full??

if you use PIP then the picture in the small screen is perfect.

I think there must be a problem with something but I don't know where to start?

The LCD TV is a Saisho SGX26 I think

Screen loses brightness at irregular intervals, then eventually returns to normal brightness.

Shut off the whole TV including the cable and the wires. Wait for about an hour and then turn it back on!

The picture on my tv is completely dark, but the sound is working fine. how can i fix the picture? because it's a fairly new tv

Keep a close look to the screen, and see whether there is any trace of picture on it. If it is there, you can see pale shadow of it moving. If it is there, be sure that the backlight is not there. Thhere is an inverter board to energise the CCFL lamps used as backlight component. If the inverter board got faulty, the CCFL lamps won't light up, and no brightness will be there with LCD TVs. Check it. OK.

I own a 5 year old 40" sony bravia lcd tv, When

This sounds like what I managed to do to my screen, even though I knew better. Is there any chance you layed the screen face down at some time?

Even though you can still watch it OK, you probably have hairline fractures in the screen face (NOT the screen itself- be thankful for that- the cracks are in the screen coating). LCD screens are a very thin glass laminate with a thin protective glass-like coating. When they are laid flat (like I did to connect cables) if the screen bears any weight, microcracks develop on the front of the screen.

I am sorry to say that the effect is permanent.

Approximately 2/3 of the screen is dark. this started about six months ago and is progressively becoming worse. when problem began the screen would recover to full brightness after it was on for 30...

Hi is sounding like a backlight is going/has gone out...these can be proffesionally replacedat a repair shop...To self diagnose if it is the backlight take a flashlight and, with tv on and while on a tv channel and carefully form different angles look into the 'dark' part of the tv screen...if the/a backlight on a lcd tv/monitor goes out(even laptop screens) then u can still see a faint image with a flashlight(or without one with a good eye)....If you still see the (tv channel) image, then it is most likely a bad backlight......
I hope this helped you some, if it did(or not) please rate!...Thank you

Black line (strip of pixels not working) horizontal across screen

If a whole line of pixels is dark, you've got a bad transistor in what's called a "Passive Matrix" display. For your future purchasing decisions, while an "Active Matrix" display costs a little more, it has individual transistors for each pixel, rather than one per row and column, so when a transistor goes bad, it only turns one pixel black rather than a whole row or column.

LCD stands for liquid crystal display. These types of displays have been around for awhile and are commonly used with computers. One reason for their big popularity is the ability to produces a better picture than CRT monitors but also being much thinner.
  • Low Energy Consumption – LCD monitors use very low amounts of power. This is why it is very commonly used in battery powered devices.
  • LCD screens also reduce the amount of glare on the screen which can be very beneficial if your TV is in a room with lots of light.
  • If an image is left on the screen too long, LCD screens are less likely to experience the image being burned into the screen. If this does occur, it’s easier to repair than other types of TV’s.
  • The viewing angle of an LCD TV is typically not as great as Plasma but the difference is not great enough to make a huge difference.
  • LCD TV’s can sometimes get dead pixels which aren’t typically covered under warranty. Although they are very small, they can become very annoying.
  • Brightness levels aren’t as great as Plasma and it’s not possible to display darks quite as dark.

Plasma technology hasn’t been as widely used as LCD in previous years but has become very popular in large HDTV’s. Although they have historically been more expensive than LCD TV’s, they are becoming more comparable in price.
  • Brightness and color are the major advantages of Plasma TV’s. They produce rich colors along with very deep blacks.
  • Their wide viewing angles allow more people to be able to watch TV comfortably.
  • The pixels of Plasma TV’s are lit individually unlike LCD screens. Because of this feature, the pixels can be completely turned off to display truck black colors.
  • The lifespan of a Plasma TV is typically shorter than other types of TV’s. The lifespan can be extended by turning down the brightness of the screen.
  • Plasma TV’s are more susceptible to screen burn-in where an image is “burnt” onto the screen when left on the screen too long such as a network logo in the bottom right corner of the screen.
  • Plasma TV’s require a panel of glass to cover it. This glass can reflect light and make it difficult to see the picture. If placed in a dark room, this typically isn’t an issue.

LCD TV has sound but no picture.

Shine a small bright light at the screen when on and see if you can see a faint picture in the dark screen. If you can then your backlighting is not functioning due to ccfl (inverter), power supply, or back light lamps.
