Hello,

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.

The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board.

I do not think it needs replacement, rather some defective capacitors are causing this issue.
Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.

The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)

You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.

What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).

You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors).
After replacing these capacitor(capacitors) most likely the normal operation will be restored.

Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.

I hope this helps.

Good luck.

SOURCE: The problem that I am

3 blinks indicate that the power source is in protected mode because one of the components of the tv has failed and now acts as a short. The only way to know for sure which is the failed part is to open the tv and measure the voltages on the output lines from the power source - the one that is going to be close to 0 will point to the failed board.
Most likely it's the power board itself - one (or more) filtering capacitor has failed, a common problem in tv's of that age. But it might also be the Y-sus board - Emerson uses old Sony parts and they were notorious in that regard.

Directv can't connect my tv to he, what can I do, they say I need a green plug in in the back,with the red, yellow, white


What I believe they are trying to tell you is you need to hook up into a component input . It is a video input only and it has three jacks usually coloured red green and blue. Match up the colours with the receiver and you will get an HD picture. They way you currently have it hooked up is a composite connection with only the yellow being for picture. This cannot get you an HD picture. The red and white is for the sound. I don't know what you mean by he though.

EMERSON PL-P42W-10A. By mistake I created a short trying to fix a light switch with tv on. after that tv shut down. not even with a new power board didn't worked. can someone help me please thank you.


Fault to its main 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. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Video settings don't hold for more than 15min


Check capacitors. There are some very inexpensive meters for this and cheap capacitors are behind many problems in electronics. Once you find it is a bad cap you can replace it or the board.

Emerson PL-P42W-10A Loud pop, then no power, AC power okTV is about 18 months old. While watching I heard a pop and now TV shows no indication of power. Checked AC, OK.Im guessing a power supply


Power supply is most likely but best way is to with a volt meter follow the voltage to see if have in and out of the power board.

IN will be AC and output will be various DC voltages.
