Question about Televison & Video
My NEC px42vp4a turns on, the menues look fine, as soon as I send a "live" video signal, it shuts down,
witha a small click sound in the left corner area..
you can see the pic for a minute or so, then off
a "menue " screen from DVD stays on, caler as a bell. yet as soon as you actually have moving video, it turns off.
any advice on the repair needed?
Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts.
In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here. ..

SOURCE: Screen Burn In ?
Nope Not unless you replace the tubes with the burn in them You have to take off ther front screen and look into the lens while tvs on and you will see what tube is burned worse. Sorry!!! but I have heard of folks equilizing the burned tubes by taking a solid color one at a time (red,green and blue) and keeping on only one color on for 4 to 6 hours one at a time and them all on at a time for a solid white and have seen some pretty good results.. Good Luck

SOURCE: Convergence Problem?
The convergence IC most likly shorted, and burnt out the b+ feed resistor. There are two IC's inside this set to control the green red and blue convergence. They are most likly STK 392-###. The ### is another set of numbers that change depending on the model of the set. They each have three amps inside each one. You really should have both of the IC's replace with only original parts, as sub parts do not hold up and will not last as long as they should. Both IC's are soldered into place and if you decide to do this yourself, please be aware of the extemly high voltage inside of these puppys. there really are no user replaceable parts inside these sets unless you have solid state repair experience. Not only will yopu need the proper IC's, but you will have to find out what was burning. my best advice, Play it safe and call in a trained tech to assist you with this repair. The price should run someware between 300 to 450.00 to repair. Good Luck Please do not forget to rate this thread.
