Samsung tv main board repair

Hi, Looks like I'm gonna need a little help from your end: After ordering a repair component kit from SJ for a Samsung plasma tv, I found a shorted MOSFET (QP801) and a shorted fuse (F801S). I replaced both bad components on the PSB. I then connected the other PCB modules and powered on the system and then I began to hear a clicking noise. To isolate the problem source, I disconnected each board one at a time and found that the main board which houses the tuner was the source. But I'm not entire sure if that board is indeed bad since the original problem was on the power supply board. Any ideas/suggestion is appreciated...Thx!

Did it work with the Y-sustain board replaced? Likely if it did not work then there is an issue with the capacitors on the Y-sustain board and the power board. Check these caps for failure and replace them with the exact type. Likely the caps are blown and cause voltage loss in one or both boards.

Why is it not working?


Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

LG LED LCD TV-I had no sound and a black screen, replaced the main board, still the same


IT is not wise to attempt repairs on LED TVs. They rarely work, and you end up replacing the unit anyway. The newer units have the LED drivers connected directly to the LED screen and there is no way to repair/replace them. Board swap/replacement is tempting, but overall the lost time versus the cost is often not worth it. Sets today are only designed to last 3-5 years. The manufacturers use the minimum rated electronic parts to ensure failure and thus a steady stream of replacement buyers. Some don't even make it out of warranty, but the manufacturers are willing to risk the cost in order to ensure that the planned obsolescence continues. Gone are the days of a set lasting 10-12 years or more. Take that into consideration when buying a replacement and only get what you need. Buying newer features that are not in full use yet only costs more and by the time you get the benefit of them, its time for another new set.

Samsung55in led tv. 7100 series. After a few minutes of being on the picture goes off. But the Samsung power indicator light remains on.


No doubt. Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Warranty Repair. My Cell phone was sent back to me but Samsung used an incorrect address. Now I am out $158 and a cell phone.


If you provided the proper information to the repair center and they sent it to the wrong place, they are responsible for it. Also did you send any information to the address that it went to in order to see if they got it?

What to do with watch repair kit


Unless the watch back has notches on it, you want to look around the edge of the watch and find a little lip. When you find the lipp, use one of the knives and pry open the back. Take one of the tweezers and pull out the battery, you could also use one of those handy-dandy screwdrivers to pry out the battery. Put the new battery in laying exactly like the old one , then proceed to close the back, making sure that the little notch (on the INSIDE lip of the back case) lines up with the stem and crown (the part used for setting the watch) so not to break it. The back openers and the knives are just differant ways to opn the back of the watch. Sometimes watches have screws on the back that need to be taken off in order to open the back case. The case vise is to minumize the wear and tear on your hands. The tweezers are for taking out the battery. If you have anymore questions PLEASE feel free to contact me I will be glad to assist you further! Good Luck!!!
