The fan has a short and its sparking and channel is blown no sound coming from it but the power light is coming on and it is green like nothing is wrong with it

ReCheck the connections.if the original power supply burnt out due to a short or system failure then you will need to check all the module boards for any evidence of burning.check the capacitors for signs of swelling or splits as these are usually the cause of no life.also I assume the power supply was the right volt/ amp as this May have blown an on board fuse on the main pcb.

Here is the link for the user manual if you need it; http://www.necdisplay.com/Documents/UserManuals/PX-61XM1A_MAN_2ed.pdf Check page 54 of the manual (61 of the pdf) right at the bottom. The lights you have indicate that either the power supply citcuit, the screen, or one or more fans have been damaged. If you are sure all the fans work, then the power supply is the only repairable posssibility. replacing the screen is not worth it. The fact that the fuse blew but doesn't blow again makes me suspect one of the transformers or capacitors in the power supply has blown, causing the short that blew the fuse, but also then melted the short so it no longer blows the fuse. If you have a multimeter, and ideally an ESR meter, with a good photo of the power supply unit we can hopefully talk you through what to check - otherwise get a repair shop to look at the power supply. Hope this helps :)

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.

it sounds like it could be a blown channel in the amp. if the sub was blown it would still work just sound horrible. i have blown many subs and amps. you can bring it to an audio shop near you and they can fix it. i just got one of my channels fixed for 35$

from your description it looks like the unit is short inside or the power supply of the unit is blown
let me know if you want to fix the Amp

Sounds like the lamp! Pull the lamp out and look at it.

Sounds like its a problem with over heating. open unit clean out all dust and dust bunnies wich compressed air. check that all fans are opperating. (fans on 6x100 amp units or thermal controled). If amp goes into protection prior to fans turning, there is your answer. the @ power supplies will have a green light on the output side. if the light in on power supply is good. or you can check that the output voltage is at 48Vdc on both units.

RED LIGHT MEANS THERE IS EITHER WIRES TOUCHING OR A BAD GROUND. IN WORSE CASE SCENERIO THE A CHANNEL IS BLOWN

i have a Philips 37pf9975/12 and after about 1hr it switches itself off the green light stops on the side but you loose picture and sound. if you push the stand by button it clicks for about 1 min and then turns itself back on???????

most likely the horz output is blown and voltage regulator is shorted. I f you have a muti meter you could check if they are shorted that will tell me if the power supply is ok.

I beleve at this time you should be careful this is high voltage off of flyback is 30.000 volts

See if there is a local repair shop who charges cheap road calls. I think you are
looking around 295.00 to fix.


thanks DOCTOR VIDEO
