Hitachi 32HB6J51U no picture; inverter, mainboard or T-con?

It does sound to me like the T-Con. If you can change the channels even though you can't see the picture then that's is a T-Con problem. Especially as you can see the lights. Before replacing any of the boards check for bad solder joints and poor connections between the boards, as the TV does sometimes function right.

Sharp Aquos LC60LE632U 60" TV 1080p. LCD HDTV. Great picture. Except, there is one green line, running vertical down the far right of the screen. I'm suspecting that it may be the TCON Board.

I had a similar problem with my Sharp Aquos 60" LED and it was the T-Con Board. Simple to replace and can be purchased in the neighborhood of 40.00. If you have sound and a picture, T-Con Board replacement should be your fix. Great videos on youtube if you need assistance. I would highly recommend that you watch the videos prior to proceeding.

It could be a bad T-con, but it could also be a faulty LVDS (cable that connects the t-con to the main board), or you can have a main board fault. It sounds like your panel isn't getting power. The T-con board should be located top center on the backside of the set. It should be housed under a metal cover. BEWARE, some panel have the T-Con built into the LCD panel. If this is the case, you will have to replace the entire panel if the t-con is bad. Simply go to, and type in you actual TV model # in the search box. This will bring up all the parts available for your model. The results will also bring up pictures of the parts so you can see exactly what they look like.

I have an insignia NS-LCD37HD that has backlight and sound, but no picture. I can tune the tv and hear the channel changing, but get no picture. I don't see any damage to either the main board or the...

Chec to see if you are getting 12vdc at the T-CON board power input pin first.
First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board.
if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there is some troubleshooting you will have to do to find out the causes of the problem you are having.

People any lcd tv with a white screen cause by the T-con board if you have some experiences you can check with a multimeter the (smd) fuse on the T-con board it is right in de middel on top in the back of the tv. you might have to move some of the boards to get to it. if the fuse is broken replace it with another smd fuse otherwise relace the t-con.

Picture died, no display only sound

Do this test and it should tell if the lcd panel is bad or not, turn the tv on and touch the screen in the center, push with your finger firmly but not to hard, if you have a backlight or light shows up around your finger then it is probably the T-con board/panel, the T-con board is attached to the lcd panel and is less expensive to replace, if you do not have any light then it's probaly the power supply
