Question about Televison & Video

1 Answer

I have a Samsung 50" plasma TV PN50B450B1D it does not turn on and it clicks the red light blinks too... I took apart the back of it and the capacitors look fine.. I think it may be the power board... But I don't know the part number to order it... Has anyone actually fixed this tv with the same problem?? Thank you in advance.

hello, amigo if the all the caps are godd then you have to replace the power supply board. don't try to fix it this is not an easy task. you are looking at almost $200.00 with tax an shipping. just go to google and type your tv model # and ask for the power supply board or just look for the part# on the board itself. good luck

SOURCE: I have a Philips 50 inch plasma tv. The light is

I have Philips 50 inch plasma TV purchased almost exactly 3 years ago. Completely out of warranty. Paid 1999 bucks for it new. Now Plasma TVs similar to this are 800 bucks. I figured the cost of a repair tech coming to the house would be around 500 bucks.. so I decided I could "do no harm" and look at the power supply. Sure enough, two 3300 uF caps were swollen.. I am far from a true electrical repair person, and if it were not for the caps being swollen, would have no idea that they were bad. I am however a little bit skilled in soldering. So I ordered replacements for about 8 bucks. The caps were actually only 1.50 ea. but the min order fee and shipping brought it to about 8 bucks.. I got them from studiosoundelectronics.com . They came in today and installed them... to my astonishment, my TV works as good as it did when it was new... I must say that I am dissapointed in Philips.. and will never buy another product from them. If it is out of warranty.. they will not even talk to you.. I don't think it is too much to ask when you spend 1999 bucks on a product from them.. I expected my TV to have more than 2.999 years in life in it. Thanks a million to this site for providing soulutions for folks..

Your problem is caused by a power supply issue it sounds like a capacitor is leaking or has vented and will need to be replaced if your comfortable you could check the power board for a can shaped electroletic cap that has vented it will be puffed up on the top the value is printed on the side you can or have someone replace it that should take care of your problem the power board is the one where the AC cord plugs to or leads to

SOURCE: Which Replacement Power Board for LNT4665F Samsung LCD TV?

Howdy,
It would be a lot cheaper if you just replace the two caps that have gone bad. Just get a cheap solder pencil from the store and about an inch of solder and you are in business.
The Power Supply Board is the center Board (towards left) after you remove the back off the TV. Remove Board from TV with the 6-7 screws. Replace capacitors CM852 & CM853; 2200ufd 25volts.

Thaks for using FIXYA, BIG IRISH.
