Screen blinked and then there was a dark band across the top of the screen


This sounds like one of the back lights have failed. This could be its power supply, and or the lamp itself.

Not all the screens can be service for back light failure. This is design dependent. Also, if you are going to change a back light and you can, it is best to replace all of them at the same time. If not the coloration of the screen will be different from one part to the other. With age the color of these lamps changes a little.

I would suggest with such an old set, I would get one of the newer LED/LCD sets. They are very far improved over the one that you have. Your set will be expensive to service, if it can be serviced.

I have a proview lcd screen and it palys the tv shows in back ground but it's a dark screen like dark blue no picture. Volume and everything working but just no picture. What can i do.


Show a torch light on the screen for a distance, and if you can see the picture, the backlight is not lighting up. Check for its settings on the remote, if you have that option. Check also the settings of brightness/contrast/sharpness/color. If you still have problems, please call in a qualified service technician.

Standard television spot after bright screen


A explanation that may tell you what is happening:

Some of their sets had this issue. The picture tube has a metal screen inside directly behind the stripes that make up the phosphor coating on the inside of the picture tube.

It is called a shadow mask. It has perforations that line up with all the stripes on the screen (look close--red-green-blue stripes all outlined in black--tiny).

What is wrong is not fixable even if the tube is replaced----the metal used in these sets for the mask contains iron which causes it to expand in areas with real bright scene changes--

No need to remove question as I saw it and answer questions for most TV area problems.

I actually ten years ago worked for Circuit City--saw at least 5 sets (all larger Toshiba sets) with this issue. On seeing first one called our support staff and someone explained to me the issue---that set was under extended warranty and since the customer was angry the set was "exchanged" for a brand new set and the old one was disposed of.

Dark Color on TV. Can't adjust the color correctly


Having same problem now for a second time on a 57T500. First time was a bad green bulb that was covered under warranty. Only lasted 2 years....currently debating wether to fix or buy a new set. Bulbs cost about $300. Set is only 5 years old, so very dissapointed with quality.

Dark picture


you know it sounds like the same problem i had....
look this is something you can try.... "turn the tv off and unplugg it!!!"...you'll need to take out the lower front part of the tv......(where the speakers are to be exact) on each lower end you will find 2 screws..Be careful it will open to the side and there are many wires, i suggest you mark them to know where to put them back...then right in the middle there will be a black cover with about 5 screws..take them out....and look at the very bottom you'll see a thing with 6 pegs....the top ones are for the screen "DO NOT TOUCH THEM"...the ones on the bottom are for the colors...re adjust them...the left one it's for blue, the middle one it's for green and the last one it's for red...

I had the same problem after i moved....and after i re adjust that the tv looks super...
i hope that helps..:P

LCD TV picture screen very dark


I have the same issues with my Westinghouse LCD set. I've found that going into the settings (using the TV remote) I can get it back to a bright picture by selecting 'restore factory settings'. It is aggravating and a pain, but I can correct it.

It only seems to do it on the analog stations, not the digital (HD) ones, so maybe it will go away after the conversion next year.

Hope this works for you.

The picture on my JVC TV is too dark


On the inside of the TV, on the flyback transformer there should be two controls. Turn the one that says "screen" very slowly clockwise while looking at the pix. The pix should get brighter as you turn it up- if you go to far you will see lines in the pix or the TV may shutdown.
