Coppell TV Repair offers a repair kit for a problem developed in Samsung power supply board PSPF701801A / LJ44-00183A as shown on the picture and used in Samsung PN58A550S1F and possibly other models within the PN58A550 series.
The failure is manifested by the TV failing to power on even though there is a standby power and responds to power command; TV may be producing a single or multiple series of clicks.
A more reliable indication that you need this particular repair kit would be a visibly burned component RTQ801S or RTQ802S located close to the two white relays on the left side of the board (see attached picture).
If neither of those components is visibly burned then there may be other problem with the board and you may need to use our repair or exachange service instead.
Important note 1: We do not guarantee that this kit is all that you need. It gives you the essentials which cover easily 90% of all cases, but the proper diagnose and coverage of the remaining 10% even when problem is properly diagnosed are your responsibility.
Important note 2: We offer this repair kit as well as a repair service and , subject to availability, boards for sale. The later two come with warranty while the kit is only covered up to the moment where you solder the components from it! If you want security check our online store and choose a repair service or a replacement board instead!
