Question about Dell W1700 17 in. HD-Ready LCD Television

1 Answer

No picture....just blank screen.

Some people has told me it maybe my backlight or LCD Inverter that is bad, but I don't know...if anyone can give some help on how I can troubleshoot the problem, that would be great! I currently have the 'back cover' removed but don't know what to do from this point on.

    honestly, I could not figure out how to change the channel to "watch" a DVD so I can see if I can hear sound or not. I have turned it  ON and turned the volume UP and I can not hear anything. Not even static sound.

This does not seem to be a power supply issue but rather an issue with the backlight inverter board. When the screen goes black, take a flash light and focus it on the screen from a close distance and several angles. See if you notice a very faint image. Try changing the channels to make it more noticeable. Try it and let me know

The picture wont stay on the screen, sound will work, but i cant see it (the picture), if i turn it off for a few minutes and then turn it back on it works for a little while, but eventually it will go...


This is a backlight issue. LCD televisions require a light to be on permanently behind the visible LCD. This is usually provided by tubes called CCFL or cold cathode flourescent lamp. There will be multiple lamps arranged around the edges of the screen. It sounds most likely to be a due to one or more bad capacitors, which can be easily replaced by anyone experienced with electronics.

It could be a faulty inverter transformer but this usually causes the backlight to switch off within seconds of switching on due to protection circuitry in the inverter controller circuit. If the inverter circuit is faulty then the inverter board can be replaced.

If you are not competent with electronics then take your TV to be repaired by a qualified Tv repair engineer.

PLTV 26 LCD TV sound-no picture


I would suggest to check the 24 volts from the power supply to the backlight inverter board. If the voltgage is missing or lower then 20 volts, the power supply is defective. If the voltage is correct, you might have a defective light inside the TV behind the screen since you've replaced the backlight inverter board; you now the failure is not there. The lights are connected to the backlight inverter board.
Let me know if you need further assistance.

My sony vaio vgn-n365e screen is Dim


The fault could be a faulty CCFL lamp or inverter.
To determine if you have a LCD screen, inverter or video card problem, read this and follow these 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.

Screen backlights on & sound, BUT NO PICTURE


If the backlites are on the it is not the inverter or power supply. Better look at the digital / Main board.

Blank Laptop Screen


Either the LCD inverter or the LCD or, at the very least, the backlight in the LCD, is faulty. You will need to replace either your LCD inverter or the screen itself.
