Samsung LE40M87BDX LE40R88BD repair

Ok, my five-year-old 40-inch Samsung TV wouldn’t power on. It took longer and longer to power up as the capacitor had probably reached its end life. At first, it took a few extra seconds to power on and the TV made the ‘clicking’ noise a few more times when I pushed the ‘on’ button. These number of ‘clicks’ increased gradually over a three-month period and it got to a point that I needed 20 minutes to power up the TV. Once the TV is up and running everything is fine.  This told me it has something to do with its capacitors. After 30 minutes of Google reading I found I could repair it myself. I just didn’t have the time. A trip to PC world and Comet and I found out they wanted £100 just to look at it, so the decision was made. I would have more joy burning £100 than hand it to these clueless salesmen. A simple Google and a soldering iron did the job. What you need is a repair kit that consists of four capacitors and a soldering kit. Repair kit costs less than £10.

Remove all the screws from the back panel and unscrew the circuit board. Don’t worry about messing up the connections as each connection head/socket is different. Follow the instructions from the repair kit or Google. You basically just need to remove the four original capacitors (in blue) and solder in the four black ones, which you buy from any online electronic stores. Heat up the joining points of the four original capacitors (blue) from the back to melt it in order to remove it. Solder in the four new ones (black) making sure you get the polarity right. Reconnect the cables to the circuit board and replace all the screws. Saved myself more than £100 and a 40-inch TV as it was destined for the junk yard. Time = 2 hours. Cost  = £10 for repair kit that consists of four capacitors which I got off eBay.  It would have cost me more than £100 just for the store to have a look at it. They probably would not have a clue where the fault lies.
