20 Most Recent Norcent Technologies PT4231 42 in. HD-Ready Plasma Television Questions & Answers

probably not a good idea. plasma monitors have been quite a problem. when an image moves it will leave a some of its self still be behind and be in the way of the next image in motion. this will happen if the plasma monitor is on too long, because plasma is a type of liquid that has been known to over heat and burn into the screen. so im just giving you a heads up before you do it. the best screens to use are LCD screens, because unlike plasma and LED, it wont overheat and ruin the monitor

The power supply is weak and needs to be change out, go to www.partstore.com for new power supply.

The continuous flashing indicates that the power source is in protected mode: another part inside the tv has failed, it draws an excessive amount of current and that has been detected by the safety system of the power source who has shut it down to protect it and the rest of the tv.
Since the status light goes to orange for a few moments before going red it means that the problem is outside the power source. The most probable cause is indeed with the mainboard; if it would have been one of the Sustain boards the failure would have been much more brutal and instantaneous (no orange on the status light) .
To certify that you will have to test the mainboard with an oscilloscope to find out if the processor is operational. If you don't have one just swap it.

You have a bad LCD driver that can only be fixed by replacing the LCD screen. Chances are the cost of the screen exceeds the cost of the TV, and if you're not under warranty I'd recommend a new unit.

Hi


Thanks for using FixYa. From what you have described it seems the issue is with the power board or the main board we’ll need to check few things. When you open the unit up; take a look at the power board-the board where, the power cords/plugs goes into. You might see some filter capacitors a little bulged up in the top-If this is the case-this is your defective part(you can try to replace them-but some soldering equipment is needed). If not, then probably the main board has gone bad. This is the other board-where all the inputs are going into. All this is only recommended if you have electrical expertise and know how to solder/re-solder components. Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

What is model number printed on back of TV?
Have you removed back and Looked on power supply board for Bad capacitors they will be swollen.vented or puffed up on top?
1000uf 16v 220uf 330uf 10v and does your set have cpu fan for cooling some have it some dont, if you do make sure it does not have dust or dirt on it.

U have white or red colors output.Tries one of these will work.Must tries and investigates that all.

Hi,

I only hope you have connected the tv with a stabilizer or is it inbuilt? This might be because of Voltage fluctutations. Also, check the connectivity of the internal power card.

A Sleep timer on your TV has nothing to do with the connection or service provider. Yes you can use a timer to turn on and off your TV. this is not provider specific. Thanks for you good ratings

Take the TV Back....bad transformer in it, not worth fixing unless you're under warrantee or have extended service plan. Replace if you can as NORCENT is bottom rung of these types of TV's. If you don't know or haven't heard of them, don't buy them...from a guy who sells these things!

im afraid to tell you that your display has gone faulty there is nothig you can do apart from change the display contact the shop where you got your set from they should be able to help you.

No on the contrary, most defective components on a defective board will malfunction when they reach operational temperature, and a chemical called component cooler is often employed to locate the faulty component. Semiconductors are weird as some malfunction when cold and work fine when warm, but the majority will fail when operating temperature is reached. If you need assistance please let me know.

Thats usually related to the control board being defective when its across the entire screen, But check the ribbon connections on the control board

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?

I work in computers for the most part,

Please ask Slinteriors

Thank you,

I had the same problem too. It called the Y-main Board. It cost $145 if you order directly from Norcent itself. I hope that help.
