Potentially so, however I would get the TV fully checked over by a professional if it has been subject to a surge. If a component further down the line caused the initial surge replacing the blown cap will only result in another bang as soon as you plug it in.

    Thing is that when it exploded it took most of the rating info with it, all I can gather really is that it's 10kv. And the rating above that starts with 10. Tried Maplin but they've only 100 volt, I've added some images

if you have replaced the fuse already then you know how to open the back of the set . The problem is more than likely one of the diodes in the rectifer circuit . They will be the four large black components The bad one will have to be desoldered and a new one soldered in its place . It will take a small amount of technicial ability but can be done easily at home.

philips has a problem with bad caps(swollen)in power supply-try shopjimmys.com enter model number-scroll down til you find power supply-order it simple to put in.if they do not have it write down part number then google it to find one--you also can change the bad caps yuorself if you are handy with a soldering iron

Oh yeah, you can most certainly change the power supply by yourself.

It's easy to locate - just follow the power cable - and easy to replace.

Only make sure to let it discharge before you operate it. 10-15 minutes disconnected from power should do.

However, there's no guarantee that the problem is in the power board.

There is a very good chance it is, in fact, not there.

There's another board which commonly fails on many plasma TVs and the effect is exactly as you describe. It's called Y-Sustain board and you can tell which one it is by looking at the side of your TV and seeing which large board has manny plastic connections that enter the display on the side.

That board often has one or two fuses on it - I'd check those first.

I have just got a 42'' philips lcd cineos model


You could have shorted out the mainboard from the power surge. If this is the case, you may only need to replace some capacitors if you are handy with a soldering iron.

If you don't have soldering experience, I would recommend replacing the whole board. Search around online for the schematics, or replacement board for sale

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. You might be lucky it's just a blow fuse. Also a defective transformer can cause your TV not to power on.

All these can be checked on the power supply board.

But more often bad capacitors causes problem on the power supply board. I do not think the power board needs replacement, rather those defective capacitors is 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. Or you can by a refurbished complete power board to save you some stress.

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.

Regards.

U have all the tools and understanding basic electronic and also can do basic soldering?Yes.The tv power supply board,that the board,where the power a/c cord plug into it.Check the whole tv power supply board carefully for dying capacitors components parts.It is usally have bulges or puffing up capacitors parts indication of components capacitors parts are dying and needed replacement.Replacement for those new capacitors component parts with the same Micro ferit and the voltages of those new components capacitors parts in a higher voltages like 5 or 10 voltages higher than the old components capacitors parts u are replacing for a better heat resistance for the tv operation of the tv power supply board for later on tv use.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Please call Memorex customer service at 800-919-3647.

Unfortunately, what you're describing is a repair issue. You won't be able to address the problem with troubleshooting. There is a part inside the TV that needs to be replaced. If the TV is less than one year from the date of purchase, it is still under warranty. Call the number above so that you can have the unit repaired.


I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please post a comment if you need additional assistance so that I can help you further.

My wharfedale lcd42f1080p just went bang when plugging it in!!


Sounds like something else in the power supply. The surge inrush current could have blown the bridge rectifier. (device which changes AC to a pulsating DC for the power supply). You may need to have the power supply serviced or replaced.

Please help my Polaroid 37" lcd


Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
Search the site by type in the "brand name" to your device; in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.
