Question about Norcent Technologies PT4231 42 in. HD-Ready Plasma Television

Eske told me to ask you

Firstly, thank you for your reply. I don't have a good camera, so I'm sending you a pic I made. The thing is that the TV reaches a certain temp. and then these vertical lines show up. Like I said they are sporadic and only visible on darker pieces of picture (black or grey). Thank a lot for your trouble.

Please go to www.tv-forums.com, enter the tv repair forum, then you will see a feb. 2nd post by krjandsue regarding a soyo tv. open that post for a detailed explanation of the problem, including pics....


Good day!!!

Sorry for the late response because my internet connections got problem hope you understand..

OK,First thing I need to know if the board on the picture in the forum is the original board of your TV or it is the board you purchase..

If that is the board you purchase I think that board is the exact replacement however it different on the version of said board..so that the TV works fine but the remote is not function..Or the IR is bad..

try to see the version on the original board to the new purchase board if the same..

check the encircle part of main board need to compare..

If they are the same the problem I see is the IR sensor try to clean it first including the glass protector before you replace it..

But if the problem is different version no choice you need to replace the board or contact the store where you buy it and ask for replacement..

Just keep on touch to fix the problem..

Hope it helps
thank you

My remote is not working the tv. I have changed the batteries,


Hello,The first thing to do is to check to see if the problem is with the remote or the TV. You can check to see if the remote is sending a signal. The easiest way to do this is to take a digital camera or a cell phone with a built in camera. Point the camera at the top of the remote and press then press any key on the remote control. If the remote is sending a signal you'll see through the phone or camera screen a light illuminate on the top of the remote. If you see this light then the problem is with the TV. If you don't see this light you will most likely need to replace the remote with a universal remote or provide a model number to see if an original is available.

My kid put a plug from the computer no power to it and it just went off it was pluged into the serivce port


It's probably just a fuse.
I don't have a physical layout of that TV inside though so if it's blown, I'd need pics.

Here's the possible good news though.
He may have simply tripped the power supplys' protection circuit.
Unplug the TV for 5 minutes and plug it back in, it may be fine!
It takes a while being unplugged to reset the power supply when that sort of thing happens.

If the TV still won't come on, you'll need to open it up and get some good shots on the power supply board and the board that the service port is on, and of the cable that connects the 2 of them together.
If the pictures are good enough, I can point out where the fuses are.

If the photos are necessary, post a comment or reply here and I'll give you an address to send the photos to.

Input locked came up on the screen now the tv will not stay on


Same thing happened to me. What you do is call Vizio, tell them your input locked problem and tell them you want them to send a USB , to try and fix the problem. i heard they will not offer this option, you have to ask, they might refer to it as a "firmware update". i told them a white lie, that the same thhing happened to a friend of mine and they told me that vizio sent them a USB to fix the problem.they will send you two different USB devices to plug into your TV and directions. Follow the directions and it will fix your problem.

Eske told me to ask you!


Are the vertical lines across the entire Screen? If so it could be the control Board. If the lines only go part way from the top but not all the way to the bottom. Depending on where they are it could be the x boards. can you post a picture of your screen with the lines?

DIY light engine


You have a defective light engine and you do not have to be under warranty for Hitachi to replace this part. We just went through this and here's what you need to do. Call Hitachi's customer relations department at 800-654-7013 and tell them that you have a defective light engine. They will act like they've never heard of this problem but they have. They will give you the names of some certified dealers in your area to call. Once a tech comes out and confirms that it's the light engine, call Hitachi back and they will send a brand new light engine to the dealer and Hitachi will cover the cost of the part (cost $1500).

Here is the deal, if you're under warranty, Hitachi will cover the part and the install. If you're not under warranty, all you pay is the install. Our install cost $400. Others on this site have paid $200. Do not let anyone tell you that you have to pay for the light engine part...you do not. Hitachi has not recalled this part but they are replacing it for free. Also, deal only with Hitachi customer realations number that I listed. Good Luck
