Hello Torr276,
Sound like you have either a bad LCD panel or a bad Back light inverter. The first thing is to start with the back light inverter. Its much cheaper. Replacing the inverter normally fixes 88% of all set with that type of a problem. You can request this part from www.interactiverepair.com

Best regards

Sustain board fault. Check and replace the faulty one. Check the electrolytic capacitors at these boards. If you wish to get some details; check the site linked here. Pull up older posts.

50" RCA LED LCD tv. The image is just a blank background with colored lines sweeping over the screen. I've replaced the t'con board and nothing has changed. Any ideas, suggestions? I'd appreciate it.


Your display panel may be bad. If any of the ribbon cables were stressed it could also cause this. There are two other boards that control this. the ysus and zsus. On some tvs they can be replaced and other thay can not. The best way to tell is to try and unhook one at a time and see what the picture looks like. If you can not unhook those boards then the display panel is bad and can not be replaced.

This is a command fault. The Inverter is the most command reason.

When turned on it has no picture but sound works


hello!
if your TV stays on, display glows, but there is no picture, most likely you have faulty t-con board and/or display itself. I've encountered the problem with both lately. I'd start with t-con(display adapter) board. it's not hard to replace and cost around $100 top. If that won't solve the problem, then it's a display panel itself. not an inverter, which is the part of power supply, but panel itself. Before replacing t-con, try to reach display's ribbon cable connectors, plugged into t-con board. disconnect first one and turn set on. If you see half of the picture, the display is bad.
If nothing changes, reconnect that cable and disconnect another one. If you see half of the picture, display is bad. If, still you don't get any picture, that's your lucky day! Display is good, t-con is bad. Replacing the display panel will void any reasonable repair option. Those crooks at "parts distribution' selling displays at the price of your TV, when you bought it: $1,500-2,000+. i don't understand why do they practice rip off. most likely to encourage customers to buy new junk and receive hefty bribes from "peoples republics" to stay in business. Anyway, it's a crazy globalism. that's why our country in default.
good luck with your project,
thanks,
Alex.

I was watching TV and "puff" I lost the image, I still got audio, I have no idea what it can be the tv is only one year old (LG 50" J550)


Hello,
Problem is in either power supply or the Y-Sustain board.
The Y-Sustain is a relatively large board out of which go connections to the side of the display; it's therefore closer to either the left or the right side of the display, has at least one rather large heat sink on it and fat power cables connecting it to the main power supply.
Often there are fuses on that board - one or more. Check those.
if they are blown you can try to replace them, but expect them to blow again - usually the whole board needs to be replaced.
Hope this will help out to solve the problem....

I have a Insignia 32 inch LCD TV Model number NS-LCD32. It recently started displaying no inputs. The backlight comes on but no inputs/ no sound. Green lines display if you press the menu,input, channel...


The first troubleshooting step would be to measure all the voltages from the power supply to the other circuits boards specially the 5 volts going to the main board. If you have the following: Insignia 6HA0112010 Power Supply, check FU502 for open conditions.
If all the voltages appear normal, then the main board should be replace since is hard to find individual components for a component level repair.
Let me know if you need further assistance.
