ITEM DESCRIPTION - PLEASE READ IN FULL!
Coppell TV Repair LLC offers you the essential components needed to repair the Va tract of power supply board .PSPF531801A as shown on the picture.
The board is used in a number of 50'' Samsung plasma TV models such as HP-T5034, HP-T5044, HP-T5054 and possibly others.
The signs of failure are usually visible with naked eye in the form of burned / blown open transistor QX801 and/or QX802 and usually burned pair of resistors RX833/RX802 and/or RX803/RX832 which are closely located to the transistors at the bottom of the board.
Whenever the resistors are blown it is almost guaranteed that the SMD diode they are connected in parallel with is also blown.
Transistors QX801 and QX802
SMD resistors RX802, RX803, RX832, RX833 (all with the same value)
SMD resistors RX804 and RX805 (same value)
SMD diodes DX803 and DX804 (same kind)
We recommend that you replace all of the above components although it is not uncommon for some of them (like RX804 and RX805 for example) to be intact after the failure.
Diodes on the board are especially hard to test since they are in parallel with the low-value resistors; we always replace the one from the group with blown resistors and usually do not replace the other....so far without problems.
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: The kit requires advanced soldering skills! A generic 60 watt soldering iron is not your best tool when handling those! Use at your risk and if you think this is not for you, use our board repair service instead (or someone else's of course).
All parts are brand new. We use the same kit in our own repair facility.
We - Coppell TV Repair - specialize in LCD and plasma TV repairs and we have fixed hundreds if not thousands of such boards - locally and through Internet.
See the reviews for our work and check our website and our blog there for some helpful information.
We can and will try to support your efforts within some reasonable limits, but we can not troubleshoot your board remotely nor can we spend the time to teach customers on individual basis how to troubleshoot.
If that does not sound right to you or if you doubt the quality of our product, services and advices please do not purchase from us!
The default shipping option for the kit is via USPS First Class Mail.
