I have an Acer AL2416W monitor which is playing up. When switched on it gets very bright after around 20sec and develops bright vertical lines. The images is frozen and the whole monitor goes dark (but backlight still on) within a minute. Seems like the t-con board? Has been serviced before with the same problem, but am not keen to put too much money in again. Likely to be the t-con, how much is it and where do I get it?

I have a Samsung LN40A550P3FXZA that is giving me problems. When I first started noticing problems I would turn the TV on and I would hear the power-up sound, the backlight would come on and then the red LED would flash a few times then the backlight would go off and it would repeat (power-up sound---backlight on---LED flash---backlight off). It would do this several times. Sometimes I would be able to get picture if I hit the source button on the side of the TV when the backlight first came

I have an ELCHS321. My backlight started to flicker. The inverter board is JLS-05-32EI. I have the back open and noticed that the LED on the inverter board was blue and flickering as well. As the set warms up the LED turns white but still flickers. The LED goes solid white and the flickering stops. Is this caused by the inverter board or or the backlight. Is there anyway to load the inverter board output to isolate th problem.


I would suspect and check first the voltages going there to see if low when cold and come up and if they are moving up and down when it flickers----points to problem in power supply ... Element ELC-HS321 32 in. LCD TV

I have a Vizio TV VO320E model that I bought with a bad image problem. I have sound and it responds to the remote. The image is white with vertical lines that move across the screen. The T-con board is attached to the LCD panel, it is a small card measuring 1 "x 16", Two flat cable going to the LCD. I do not know if the problem comes from the main board or the T-con board (attached to the LCD)? There are several main board for sale on Ebay. Can you help me determine which one is failing.

I have a vizio vz37l tv. When i turn it on the screen lights up, however there is no picture on the screen. the sound works, its just no picture on the screen. I read on a couple of the posts on here, and figured the proper course would be to replace the t-con board. I just finished replacing the tcon board and still the same thing. I called vizio about the problem and they say that if the screen lights up then the problem wouldn't be the backlight inverter boards, that it might be as simpl

Samsung SyncMaster 305T One-half of the screen (the right-hand side) gets dark. It turns black and I can barely read the text in a document. This problem is NOT consistant. In other words, some of the time the right-side lights-up and looks normal. I have read some of the other expert answers and it seems the flourescent back-light bulb is the problem. My questions: 1) Where can I find the part number for this bulb and who sells them? 2) Is there another part in the circuit that may be the

Viewsonic n4060w black screen, no video sound ok. So I've been reading this forum about the problems others have faced with this tv. I decided to purchase pair of inverter boards. After installing them the same problem, no difference. I swap the boards to see if I can find a defective one, nothing. I can see the black backlight on, I have replaced caps on the psw before. Can I suspect the psu once again or am I missing something?

I have a Sanyo 42 inch Mode Number: DP42647. I bought it 2.5 years ago, and suddenly, the video is out. The sound is ok, as well as the "power" green LED. By looking at other forums, it seems every Sanyo TV purchased in 2008-2009 has the same problem. Some owners report having their units taken to a technician, and their response is the "main" board failed. The main board in my TV is: N4VE MAN. I can remove it, and buy it online. Should I be worried about having more failed components?.

I have an LG 42PC3D Plasma set. The set would not turn on so I did some trouble shooting and found and replaced all the capacitors on the power board. Some were bulging so I decided to change all of them. I also replaced the shorted IPM (the large chip under the heat sink) and related fuse on the YSUS board. I now have a working set again. The problem I am having is the much typed about "red sparkles" on the left side of the screen when a dark background is present. I have read many posts abo

I can't get my remote to work. It seems there is a problem with the sensor on the TV. That's not the main problem. To see if I could get it to work I decided to reset to the default factory settings but when I get to the Installation guide and it asks for the country the buttons on the side of the TV cause no response. I've tried unplugging the TV but now every time I turn it on it goes straight to the Installation Guide and that's where I'm stuck at.
