Question about Dynex DX-LCD32-09 LCD TV

2 Answers

I have a Dynex 32 LCD that I can only see the top half of the picture, the bottom half/40% looks like rainbow lines. What are the possible problems and how do I fix it.

Originally, this problems occurred for a few seconds once I turned on the tv, then it went away. it then progressed to a few minutes and is now constant. I have opened the back and checked all of the connects and have not found a loose one.

Hi Im Alienware X51 and i thinck i can help you.
ok what you have there is a picture problem from the T-Con board of the tv. actuali tv screen don get fried never. the only thing is seeng a broken screen. but your problem is picture problem. open you tv again and look for the t-con board on lcd tv is located on the top of the tv panel. some times on the bottom but. you will see to flat cables. disconect one of them. then turn on the tv see if the tv looks black or completely white, if you not see it like that and you see it like rainbow then then the T-Con board has to be change. on of the side have to look white or black if both side looks like rainbow then you have to buy a new T-Con board. no dont let the main board behind. the main board may be the problem to. so chek both T-con board and main board. to make sure you're buying the right part.

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

The blue light merely indicates that power is getting to your TV. It has internal power supply problems.

LG 32LH30 LCD TV Problem


IMO Seriously for $119 it's not worth it.
However, it does sound like a capacitor problem
If you are "Serious" about fixing I'd find a TV repair Forum.
Else I'd go here and get a new one.

Dynex tv has a picture on the top half.the bottom half has a bunch of lines going vertical and no picture


It can either be the T-CON board or the main board, or LCD panel itself problem, you will need the scope to look at the signals feeding the T-CON board and the output of the T-CON board to narrow downth problem.

Trying to change tv format on my dynex 32 LCD


You are looking for a picture size, format or screen size button on the remote control to solve the issue. If it connected to a HD cable or satellite box then they also have format or picture size settings.

I have picture at the top and verticle lines at


Your panel needs replaced. Half a picture, top to bottom, provides a quick diagnostic. You panel has a Timing Control (T-Con) board failure. Watch out for part cost, it may be cheaper to replace the TV rather than repair it. I hope this helps.
