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. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

The TV is in some kind of protection mode, the blinking LED show you an error code.
Try pressing 062596 and then press menu button (do these in quick motion, don't let them to time out while keying)...see what happens
Well I think that if you would have a service manual for this set that would help a lot, I can send it to anyone who wants it via email/gmail. Let me know if anyone want one.

I also heard that this problem appeared with some people because the of the burnt fuse in the TV. To fix that it has to be taken to the tech shop. mecry.gif

And yes I also heard about this issue many times, seems like this TV set is very popular with this kind of problem.

SOURCE: Our Sony Bravia tv picture keeps going light dark

I have Sony KDL-32XBR9 and I have noticed a similar problem. When the picture is showing mostly black, for example during the ending credits of a movie, the TV will further darken the display. Once the picture lightens back up, the TV will adjust the brightness of the display back to normal. I just called Sony customer support and they indicated it was a firmware problem and they will be sending a USB device in the mail to update the firmware. Hope this helps.

SOURCE: Hello, I have a Samsung LN-S4692D.

You cannot test the T-Con bd with a meter. However if you have the luxury of having another same model tv, you can install the bought T-Con bd and see if it is good or bad. Since you said the Menu and channel flashses, then I would replace the Main board.

The red light turns on but no picture comes on


Get real close to screen and maybe use a flash light to shine on the screen and see if you can see the picture still, it will be dark and almost not visible but you should notice something move. If your screen has picture then you most likely have a back light problem. Most common problems are bad inverters, or the inverter controller card. possibly a bad power supply but most likely inverters, test each circuit, replace as needed.

The problem is that u know the sony hdv xr500x when u put it on the picture is very dark we have tried it under light too put but the picture is still dark


Hello
When you look at your pictures are they dark, murky and hard to see? If you took pictures at a wedding, dance recital, theater performance or any indoor event and they came out dark, read on to learn why your pictures are dark, and how to fix this common camera problem.

Many people take pictures of indoor events, only to be unsatisfied with the final outcome of their photos. Although you may have bought the top of the line film or digital camera, there are a few limitations that you need to know about.
To correctly expose your pictures, you camera needs a lot of light. The compact point and shoot varieties adjust for this when you're outside during the daytime, and usually your pictures turn out fine, right? Well, then how come when you take indoor pictures, they sometimes come out too dark? There are two culprits; your zoom function and your flash.
Most compact cameras today offer a zoom function. When I used to work in retail photography sales, the first feature that consumers would ask for is zoom. People love to get close-up pictures without using their feet. Although zoom does bring your subject matter in closer, it also decreases the amount of light that can get into your camera. Essentially, the more you zoom, the less light your camera can receive, and your pictures will be darker.
So, if your taking pictures indoors, in a dark church, gym or other window-less room it is very difficult for your camera to get enough light to properly expose your pictures.
This is when most photographers decide to turn on their flash. The flash on your camera is a great tool to illuminate dark situations that are in close proximity to the camera. Most built-in flash units are designed to allow the light to travel 8-10 feet away in poor quality light and up to 15-20 feet in brighter situations.
What most camera users fail to realize is that although your zoom function is visually bringing you closer to the action, you flash cannot reach that far to illuminate the subject, and your pictures will be dark.
Hope it helps, if so do rate the solution

Falsh Problem with Power Shot a640


I had the exact same problem. You'll need to send it back to Canon. It'll cost you $87-94, but they'll clean it up, get the flash working, and make it new again. It's a good camera worth getting fixed.

Flash


checking on the first 2 comments, if there is flash and the pictures are dark - please check the lighting conditions
is it a dark place, fairly lighted or fully lighted

the flash also has a certain range, the subject may be far that the flash cannot reach it

if there is really no flash - it may be a hardware problem, pls contact kodak to arrange repairs
try going to PASM> fill flash too, if still not working - repairs =)
