Hey Nascar580, you can pick up an replacement substitute part from here:

http://www.lcdparts.net/InverterDetail.aspx?InverterNumber=UI8007S-1MSS

The original part UI8007S-1 is defective and the IC chip that powers the coil will contually burn out. The replacement was designed due to this flaw.

Good luck!

Sharp LC-40LE55OU flat screen. I have audio, no video. I can shine a flashlight on the screen and see images.


The backlight is not working.
Either part of the power supply board is not working or the backlight LEDs are not working.
Unfortunately, you'll have to take it to a TV repair shop. Get a quote on the possible repairs first. Check for reviews on the repair shop.

Don't open it up yourself, there are hazardous voltages even when the TV is unplugged!

I hv got LCD TV hv No picture but have very good sound. While power put on ,it flash & go. What to do? This is for BenQ LCD TV 2680.Back light inverter is avllable? in case needed.


Hello
As you thinks mey correct to an extent. If backlight inverter board has some kind of short with its components, the fault you describes here will occur to LCD TVs, irrespective of Brand and Model. Most of the backlight inverters for any models are available at open electronic spare part shops at your town. Just take the backlight inverter board out from your Tv. It will have a special number printed on it, and should be noted when buying a new one. Remember its connections when you take the boaed out from your set. If needy, mark the positions of connecting wires to that borad on a piece of paper, for reference.
Replace the backlight inverter first. It must solve the problem of your BenQ LCD Tv. OK.

My samsung tv's backlight doesn't work can i fix it


yes; you can replace the back light of your lcd, when you remove the back cover of your lcd you should remember all the parts that you will try to remove specially the screw, then you will see a rectangular pcb in the other side it has a small transformer this pcb is the inverter of the backlight of your tv try to follow the wires that is connected to this inverter and you will see the back light of your lcd, try to check the tube both end if there is black color then it indicates that the cathode tube is already damage.

Approximately 2/3 of the screen is dark. this started about six months ago and is progressively becoming worse. when problem began the screen would recover to full brightness after it was on for 30...


Hi there...it is sounding like a backlight is going/has gone out...these can be proffesionally replacedat a repair shop...To self diagnose if it is the backlight take a flashlight and, with tv on and while on a tv channel and carefully form different angles look into the 'dark' part of the tv screen...if the/a backlight on a lcd tv/monitor goes out(even laptop screens) then u can still see a faint image with a flashlight(or without one with a good eye)....If you still see the (tv channel) image, then it is most likely a bad backlight......
I hope this helped you some, if it did(or not) please rate!...Thank you

My tv screen wont turn on but the power light does and there's no sound can anyone help?


This is service center issue. It could be a part called the backlight or the backlight drive or the 'small signal board'. Any of these will require a shop.

My HyVision LCD TV Picture disappears after a few seconds


It seems that the "backlight" has gone bad. "Backlight" is the device that allows to see the picture in an LCD TV, when they are about to go bad the symptom that you describe is very usual. It depends on the tv manufacturers and model to expect how long the "backlight" is going to last in a tv.You can shop around for a replacement part and try to do it yourself or take it to an especialized technician. Good luck..

Sound with black picture,some reflection w/flashlight on screen


The problem is that your TV's backlight has gone out. Without this light, the display still works but you can't see anything. It may be that the backlight lamp has failed. But a more common cause is failure of parts called capacitors in the set's power supply.

I've never worked on a Polaroid, so I can't point you toward any specific parts numbers or values. You may be able to find more detailed information by searching for your specific model and "backlight repair". Capacitors are cylindrical parts that vary in size depending on their value. When bad, they often have tops that are bulging (should be flat) or have split open, and sometimes there may be discolored areas at their bottoms from leakage. Replacing bad ones with parts of the same capacitance value (marked on the part in mf or uf, as in 330uf) and a slightly higher voltage rating often fixes the problem. (Not always, because other things can go wrong.) Capacitors also have a polarity, so you need to make sure the new part goes in the right way.

A TV service shop could check the set if you can't find more information or don't want to try it yourself.
