It can be because the backlight inverter board may have failed or it is not getting 24vdc from the power supply.

My element tv has no picture. (it can be seen with flashlight test) will a power supply repair kit fix this issue?


This is usually not the power board. the LED strips fail and you have 55 LED bulbs in the back light. It is not an easy fix because the display is glued to the bezel and if you don't take extreme care when working on it, you crack the LCD display.

Sharp TV - no picture, sound is fine


Hope this is an LCD TV. If it is, show a torch light from a distance and see whether the picture can be seen. If yes, the backlight has gone bad. If no, try changing the input device to something you know works. If nothing works, this is a case for a qualified service technician.

Stops and starts at random. don't have manual. craig model #cdm2891 so don't know whay all the buttons are for


Hi there.
I'm assuming this is the CD Player you own :

http://www.craigelectronics.com/product_detail/personalCDPlayer/CDM2891.html

I only ask as this brand does not exist in England. However I know that if your portable CD Player is cutting out sound, this is due to excessive movement fron being in a pocket or from being in a bumpy car. The cutting out is because the "Antishock" has not had a chance to store the music information, so instead the unit just pauses or cuts out sound.

-> Once = Skip track forward
<- Once = Play from start of track or skip backwards
Hold down either of these to fasst forward or rewind
The square means stop
II = Pause (press again to resume....sometimes pressing play will resume too)

These are universal key functions. Having not seen the item before, I am unable to guide furthur unless you can direct me to some pictures that I can see the function buttons larger and can explain what they do

All the best

Large dark shadows on display,but the menu can be seen faintly,and no control over brightness but overall brightness low.The electronics is functioning o.k, but the dark shadows block out all images...


Sounds like a Z-SUS board. This board "erases" the picture between frames and prepares the screen for the next frame. If it goes out, your picture will be very, very dark. As for the reason... It's electronics, they just break. If you want to attempt the repair yourself, you will need to post the full service model number. ex: 50PC3D-UE.SUSLLJR Otherwise, we can't get you the correct part number for the Z-SUS. I hope this was helpful.

No picture on a Westinghouse lcd tv model ltv-20v4


I had this problem with these tv`s. The problem actually lies with the power supply inside the unit. Some of the units i`ve seen have 2 blown capacitors on the power supply (C7 and C6) replacing these works. On others, the capacitors as well as a few transistors (Q8 - Q1) are blown. But on all the sets i have seen with this problem, changing the above components restores full functionality to the system.

How do we know if its capacitors or power supply?


What is the problem with your TV?
It depends where or how the capacitors are connected and the function(s) they perform in the circuitry.
If the main capacitor(s) fail then there could be some intermittent ON/OFF or a buzzing noise getting to the speakers, bad or distorted video.
If you've have seen the power board on your plasma, you will see a few of them in there.

Have sound, but no picture


Good Day, Fitz1234;
It does sounds like the lamp may have failed. I've seen this before. So, pull the lamp out and look at it, it should be shiny and clear. If it's cloudy looking then the is defective.
Good Luck, Big Irish.
