Where is capacitor located on TV


There are several.
You should be identifying the four large components
- Power board
- Logic board
- Timing Control (TCON) board
- LED inverter driver board

99% the capacitors you are looking to identify for a power related issue on the power board.
capacitors look like

How To Repair LCD Monitor


The most common problems on Samsung LCD monitor/TV:
  • The power can not turn on, the red light flashing
  • the monitor on for a while and then turn off, then the red light flashing.
This is due to the weakening of the capacitor in the power supply module.
let's go hunting for bad capacitor.


I will explain how to:

  • Open the case of the LCD
basically in all LCD monitors have two circuit boards (power supply board and system board)
  • After you open you will see the two boards are
  • You see a board that has a socket for the power source. wrote that the board we're looking for (power supply board)
  • Remove all cables connected to the board and take out the board. (get noted before you unplug it)
  • Now you see it components on board, we looking for capacitor.(see picture below)

  • Looking for damaged capacitors, physically you will see a capacitor on the top like a bloated (see picture below)

  • Replace the damaged capacitor with the same value that you can see on the surface of the capacitor. (In this step you need any soldering tool)
My advice: replace capacitors with higher voltage, like 10V replace with 16V or 25V will be fine.

Have a Nice Repair :)

First thing you should do is to invest in a really good surge protector for your TV. Then when you replace the capacitor again use a good capacitor. Cheaper is not always better. Rubycon seems to do the best for me. There may be other suggestions, however I have the best luck with them.

Screen Philips 17 inches LCD doesn't react. Power LED stays off.


Check the tv power supply board,that board where the power a/c cord plug into it.Most common problems on these power supply board are dying and leakages capacitors components parts.Check the power supply board carefully,if u have dying or leakages capacitors parts,these capacitors parts will bulges ups,will not have a flat cylinder heads like the rest of the other capacitors coponents parts.Replaces all these dying and leakages capacitors parts with the same Miro fared and the voltages little higher like 5 to 10 volts higher,the power supply board should not have this problem again.U have all equipments to do basic soldering works and u understand basic electronic wright?Then u should have no problems by replacing all of these dying and leakages capacitors parts that are bulges ups onto it cylinder heads on the power supply board.If u can't do this,tries websites like Shopjimmy.com,eBay.com to by a whole new refurbish power supply board for the replacement.

TV power supply problem


.01 mf 2000 volt. in flyback circuit .it is a timing capacitor. the red high voltage block is bad and that took out the capacitor. also check the horizontal output transistor...it is probably shorted.
