Hello sir My Toshiba LCD model 40CV600E Problem was no display but sound can still can hear.

i moved you to TV from computers.
can you see the video on the screen with a flash light.??? i bet yes.
all LCD have back lamps. that must work or turn black, or dim
use flashlight first to see data/tv presentations,,

this TV is 9 years old today
this TV has CCFL back lamps (sell it and get LED TV)
here is page 37 in your manual (ive never seen one last 9 years)
quote
The cold cathode ? uorescent lamp used for the back light on this TV has longevity. When
the brightness of the screen comes down,
or the ? ckers of the screen are caused, or
some parts of the screen do not light up,
it may reach the end of its life. Contact a
service technician.
end.

The picture seems to be getting darker. Its not as bright and sharp as it used to be. Its about 9 years old but has not been used very much. Might it need a new bulb or something? 57HX81 Proj TV Color...

simple: remove back cover and locate the three large black lens you will see top and dead center, clean them with either a lens cloth or a paper towel with glass cleaner----they are the light source for your picture and should be cleaned once a year---as they get dusty the picture gets darker and duller looking.\\

Turned on my TV today to find a 5" horizontal stripe across the middle of my screen. I can view the picture through the stripe but the picture brightness on the top 1/3 and bottom 1/3 of the screen is much...

This sounds like an impact injury to the screen itself. It is likely that something may have hit the screen or if the set is old, the part inside may be starting to go.

Hope this helps

No picture on my Toshiba 42HP66 plasma tv.

I too have this problem with no help from hh Gregg, where I bought the tv, and no help from Toshiba. I resorted to calling the BBB and complaining about the defective workmanship. I took the tv, which is less than 2 years old, apart and found the y-sus board, behind the y-sus board is a foam rubber spacer to seperate the circut board from the backside of the screen. I think this pad is designed to prevent heat buildup in the y-sus board. The pad itself is held on by glue and that glue melted causing the y-sus board to short out. I noticed this after finding a tacky substance behind the board. The heat from the plasma screen melted this and also the pad itself. Toshiba claims no resposibility because the tv was out of warranty. Thanks Toshiba.

We own a Toshiba Regza 42" direct view LCD TV. We have owned this since last November (bought as a Christmas gift). This TV was working great until last night (7/7). Powered it on and for a split...

Unfortunately there might no be a fix for this type of failure unless the LCD is open and perform a few measurements in the circuitry. Since the TV is less then a year old, I would suggest to contact the vendor or manufacturer to have it repair under warranty, most electronics devices carry one year warranty.
Let me know if you require further assistance.

2-inch picture stripe in middle of screen.

deight, your set is going into total vertical collapse, either the vertical IC is failing or some support component to the vertical circuit is failing, should not be an expensive repair, hope this helps, BMW Rider

Toshiba 42hp83 plasma power supply problem?

I had the same problem. It turned out that one of the cooling fans get dusty and does not work. I opened the back of the Toshiba plasma TV and cleaned the failed fan, and it worked like a champ.
