I have a dynex lcd tv, the screen fades to black after 10 minutes, changed the t con, worked fine for a week, now fades again

It think it might be a fault on the T-Con board. Could be a bad soldering joint or bad connection. But could be something faulty on the board itself.

Use a flashlight on the screen when it goes black. If you can see a faint picture then the board that controls the back light has gone bad. If you see no picture then the T-Con board is bad. You can get replacement parts here: TV Parts Universal TV Stands DLP Chips ShopJimmy and fix the TV yourself. It's not that difficult.

Unfortunately what you have is a fried screen. Toss it at the city dump and get a new TV. Wallmart has 36 and 45 inch TV's for under 300 dollars
Good luck

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

Sounds like you either have a faulty LCD panel tab, failed LCD driver board, LCD/t-con panel bad connection, or a bad t-con. You will need to get a diagnoses to be sure.

Hi There are a few things that could be wrong with your TV. Hopefully it's the T-con board or the signal board. The third thing is the screen could be bad. There is no way of telling without replacing the first two parts if that does not solve your problem then your screen is bad. I guessing if you are asking that it's out of warranty. I would start by replacing the T-con board. the T-con is the board that connects the screen to the signal board it is attached to theback of the screen in the top middle part. To replace parts you have to actually remove the part first to get the part number from it other wise you run the risk of ordering the wrong part. Also when changing the T-con try to change the ribbon cables that are connected from it to the screen. If the problem is still there then I would replace the signal board. again you would need a part number in order to get it. you can find parts at www.interliquidparts.com I hope this helps.

Hi msyaros
In order to have data`s specific to model , i would need the model# written on the back of the tv set.
Be waiting for your reply

The LCD Panel failed. There is no easy fix but try to get the T-Con board to fix the issue. However, this part is usually only available with the whole LCD Panel. This is usually the most expensive part in the TV and the whole TV needs to be taken apart to replace the panel.

Might be economically viable if you can find a place that carrys the T-con but Dynex parts are usually hard to find. The LCD Panel part alone will exceed the cost of the TV.

Seems T-Con board mounted at top center at rear of LCD Panel is bad.
Local TV tech will fix TV by replacing T-Con board.
Thanks.

So, where are the answers?
