The principal exception is alarm clocks which do use lamps so that you can check the time at night when its dark, but that is usually a push-button function. Unless your machine did have a light (very rare) and you remember it shining there, the problem is either in the LCD driver electronics or the LCD itself so you'll probably have to stick to the torch. Loss of contrast is a common LCD failure mode and from your TM example it seems to be an issue with that model. Was it coloured when it was readable? Cheers Billy 8-{) So the laptops, PDA, TV, and the LCD monitor have been falsely claiming to be backlit, and the suppliers charged me for a feature that isn't there? The scoundrels. ;) |

The scoundrels. ;) LOL, I was probably a bit liberal with my expression R2x1, I was referring to this application (elderly stereos) and did mention that some had back-lights, but cheap boom-boxes rarely if ever had them. The items you mention are in a totally different class of application (and price bracket). With older stuff the technology wasn't there yet and even when it did appear, with low cost stuff they simply didn't bother. Note the mention of "ancient stereo".. Cheers Billy 8-{) |

I have a small program to use the screen as a flashlight (NZ= torch) in an emergency. I could swear that mine radiates photons. |

| 745913 | 2009-02-12 12:02:00 | Could you find a similar model and scavenge for parts? | Sick Puppy (6959) | ||
| 745914 | 2009-02-12 21:39:00 | Also can we assume that it had a remote that could be programmed to fave stations but you don't have the remote any more? | Ofthesea (14129) | ||

| 745916 | 2009-02-13 04:35:00 | replace with some Hi intensity LEDs of the same colour as the original lamps or for a funky effect use some auto colour changing LEDs and watch the display change colour | williamF (115) | ||
