SOURCE: lcd tv backlight prob

You need to replace the inverter board if you can find the spare part. Otherwise you need to replace the whole lcd panel.

SOURCE: lcd, picture not showing up

We may neet to begin contacting the attourney general. Seriously we may all have to write letters. I am willing to organize this if others post a willingness to engage in this process. Samsug customer service told me that what people report on the internet has nothing to do with Samsung. I explained that I was not wanting to report to the internet, that I was calling to report my number to them. It took some arm twisting to get her to give me a contact on who to report the problem too. They won't listen to internet blogs and I don't blame them for that. However, I was reporting directly to Samsung and they did not want that too happen either. That is not ok. We need to get the attourney general involved. Who is with me?

How to fix my promac tv lcd 2051 lcd (sound but no piture)help me please


Back - light problem itself. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
http://electronicshelponline.blogspot.com/
In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should trouble shoot. Contact any service technician. The circuit will differ with models and versions.

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..
