NEC PXT-42SX1B 42 in. Plasma TV Questions & Answers
Dead, no power
It sounds like ze power supply blew when it was being turned off. This seems to be typical of plasmas. Bad power supplys wont let the tv come on and will result in no lights coming on. Since there R no lights coming on, I would suspect the power supply first, followed by the power control board,. and circuit board. It may cost anywhere from $250 to $500 to fix.
Nec pxt-42sx1b won't turn on. We press the on button on the remote and the stand by light turns from red to blue but then goes back to standby.
I see so many here with no sound/nopicture issues:ISSUES: 1. IF sound main fuse/s are good.2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.3. almost all these sets the troubleshooting involves
checking voltages on the main power board to narrow down theproblem.4. Be safe and if you do not know what you are doing don't open the set.Answers to issues:1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.3. Trouble shooting consists of the above and then at some point you have tobuy and try a board to see if it fixes it or not.4. Safety first--no TV set is worth getting injured or even killed over.
Is there display drivers available
I'm sorry for the difficulties you're experiencing in viewing the Desktop correctly when connecting a computer to the TV. Unfortunately, there are no such drivers available for TV to make it compatible with a computer.
Please understand that the image from a connected computer will not display in full screen because of the difference between the display resolution of the television and the available resolutions on the computer. Setting the WIDE MODE (Zoom) option on the television to Full 1 or Full 2 will stretch the image to fill more of the television screen but will not fill the entire screen. This is normal operation.
I have searched online and found that 1024 X 768 will provide better experiencing than other resolution. It is required to set the resolution in the computer before connecting it to the TV. Please install if graphic card updates available from the computer manufacturer so that it will give option to select resolution in some cases.
Thanks for understanding. Please let me know if you require any clarifications.
