No Video Display

The "out of production" Toshiba LCD Video Project TL P670 has great sound and the lamp (1300 lumens) is very weak. There is not video display, just sound. Does the lamp project the image or makes it bright so you can see it better or is there another part that needs replacing?

Thank You

    I am truly grateful for the response. I figured the lamp needed to be replaced however, the second part of the question was "is there another part that needed to be replaced?. There is no video and the lamp is bright enough to determine if the video portion is working or not, though it still need to be replaced. You did not say how the video is produced though you covered the subject of "light" very thorough. I will open it up and play around with it. Maybe I will discover the solution. Thanks a bunch for the help.

The lamp should be blindingly bright. The light passes through a color LCD and through a series of lenses that will project the image onto a screen. If the light is "very weak", you won't have enough light to project onto the screen. Try using it in a pitch black room really close to the screen. If you can see ANY image being projected, then the unit is fine and all you'll need is the lamp.... usually a rather expensive item.

    Follow up: Video is produced by a signal that goes into a decoder within the projector. The decoder sends the color image on a clear LCD "screen". If you held the LCD screen in your hand, you could look through it and view the image. The LCD screen is only an inch or two square. When the light from the lamp passes through the LCD screen, it basically casts a "color shadow" which is focused and resized through the lenses of the projector and onto your screen. Sorry, forgot to address that part.

Dim display on Toshiba Satellite 4090XDVD notebook


The backlight CCFL lamp provides the lighting for the LCD screen. If you have already adjusted the brightness to the max. setting and it is still dim, it means the CCFL lamp is is nearly worn out. To determine if you have a LCD screen or video card problem, read this and follow the instructions. Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp. Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case. The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills. Check out www.lcdparts.net for parts, repair service and DIY info.

I have an LT170 proj. i bought on line but it has no lamp .


You are looking at two hurdles here: 1) The lumen output of an LED light is nowhere even close to the output of a high voltage lamp in a LCD projector. 2) The color temperature of the LEDs, even if they were bright enough, will likely not match that of the lamp. This means the colors will not display correctly.

While it is a very ambitious project, I think you may be better off replacing the lamp with the proper model.

Lcd invertor


Hi,

If you are referring to an LCD inverter, this is a an electronic device that converts a low voltage DC into a high frequency high voltage AC. This output then feeds the Cold Cathode Florescent lamps (CCF) which in turn provides the necessary backlight to the LCD panel display. Most inverters are also coupled to a logic circuitry that triggers them OFF during video mute, sleep, hibernation. They can also be designed to supply multiple CCF lamps for LCD display that are 17" or bigger.
Most inverters are OEM products and it would not be surprising to find a Samsung inverter in a Toshiba LCD display.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
