Need to fix my circuit board on a LCD

My 46" LCD Samsung 1080p will power on but I do not get a picture. Had slight electrical surge. Opened the set and notice that the rectifier DP806 was fried. Where can I get a replacement one. also some of the sodering appears to have been broken but I'm not sure because I do not have a diagram. Any idea's where I can find one? Thank you!

SOURCE: Same "clicking" problem with 46" Samsung LCD...does not turn on.

With any luck you will have the same problem asa the rest of us : blown power board capaciters , remove the rear cover {20 screws} look in the middle of the back of the set with the cover {5 screws} removed from the power supply . Now look to the upper right cornerof the board in the middle of the tv there may be 1 or several capaciters leaking from the X shape on the top , this be be your problem match up replacements but source units that have a higher max voltage than 10volts 7 get them soldered into the board . I repaired mine that failed at 16 months for $4 in parts & it took longer to remove the screws than it did to affect the repair. If you are not conifident about soldering on your $2000 tv then take the board to someone for the job to be done , I would not advise this as a first soldering job , good luck I can't belive how common this is Samsung needs to step up ......

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.

Philips 46PFL5706/F7 46 LCD TV. When you turn it on you have power. The Philips logo appears for a second then goes away. Screen is black after that.
