Question about LG 23LS7D Television

Open Question

Powered tv on and few seconds later the green on/off light and picture faded to black. the sound still works, and you can change channels, but there's no picture -- just a black screen. repair person said power circuitry AND picture (or backlight?) circuitry have failed. the green on/off light problem seems to have corrected itself, but there's still no picture. is it worth fixing? any idea cost of the failed circuitry?? thanks, birdsdog

Try One of your working TVS and connect it to your cable outlet of the TV that is having problems. If that TV Does not work then there may be a degraded fitting or the Leg coming of the splitter to that outlet could have a Low Signal Problem
Next Take the First TV that was not working properly and put it on the cable outlet of one of the TVs that is working properly and if the TV set works on that Channel then you know it is not your TV that it must be the cable

The lights indicate what the issue is. Kind of like your check engine light in your car tells you something is wrong with the engine.

SOURCE: 42" LG Plasma tv, no picture - black screen, but have sound.

Most a likely a problem with your Y-Sustain board which will then not drive the screen giving a black picture. The fuse on the board may be open circuit & need replaced but most likely you will need to have the sustain board replaced.

Hey Ben, The TV is alerting you it is about time to change your light bulb, it will keep on doing this until the light bulb just dies.
Order your Bulb via On Line at any of the places, there are different prices, but average for the authentic one with the chasis included is @ 260.oo and only takes @ 5 days to get delivered. You can save up to 140.oo if you just order the pure light bulb, and go the extra mile changing it, I just explain someone how to about it, only takes you 30 mins. Good look, I hope I get help for my problem too.

Green noise in black areas of picture


I'm sure you all thought of this but if someone does not state the easy fix then the easy fix doesn't get done.
I had the same thing happen to my Sam46inch1081, it just started doing it, no slow fade in over time.
I have cable with the HD box, all I did to fix it was unplug the power from the back of the hdbox, wait a few seconds plug power back in and have it reboot. Problem was solved.
Like I said, easy fix for me, don't know if this will help you, but ya never know.
Just thinking out loud here but maybe its not your tv but some other equipment you have added to it other than the hdbox.

TV Picture Goes Black


I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions
