Samsung LE40R73 LCD clicking


The power supply pcb located in the centre of the panel has 4 capacitors on the pcb that go faulty. This can be seen by the tops on them bulging up with possible brown fluid discharge. The value of these is 1000uF and after replacing these (can be purchased from Maplins or any other electronic components outlet), the fault will be cured.

Sounds like an issue with the DM pcb. most likely some small electrolytic capacitors. you will need to remove DM pcb & take cover off. look for capacitors with bulging tops. note the values & location & replace all capacitors with bulging tops.

Value of the memory capacitor on the PCB of the LACIE EDmini v2


If the voltage and the farads are higher than the original it won't make any difference what you put in. They are not much greater than 47uf, if you think it's 10uf than put anything above that in. It will really depends on the physical size of the replacement. Get one they same size as the one that's gone and you can't really go wrong.

Have a phillips 32inch lcd...turn it on and nothing happens seems like no power at all no lights no noises...tried other electronics in same outlet and it works... wondering if there is anything i can...


This is a common problem with lcd panel tv's. There is a problem with your power supply. Here are the steps you need to take.
1. Lay the tv face down on a cushioned table. Make sure the table is large enough to support the entire tv, You don't want to damage the panel.
2. Remove all the screws securing the back of the tv to the front.
3. Remove the back
4. Check the power supply pcb for puffed capacitors. If they are puffed, they need to be replaced.
5. Remove all connectors and screws from power supply pcb. This is the board where the power cord attaches.
6. Replace capacitors with equal or slightly greater valued capacitors. The values are marked on the capacitors in mfd and voltage.
7. You wil need a soldering iron to remove and replace them
8. Install the power supply pcb back into the tv and replace the connectors
9. Connect the power cord into the back of the tv and turn on.
10. Check to see if backlight comes on.
11. If it does, press menu button and lift tv up to see if you have an onscreen display. If you do the repair is complete.

If you don't you need to take a digital multimeter and check the voltage ouput from the connectors of the power supply pcb. Connect black lead of your meter to chassis ground and use the red lead and touch each individual pin to see if you have the correct voltage. The voltage levels are printed on the power supply pcb. If they are non existent, then you need to replace the power supply.
You said that you have no power light indicator led on the front panel at all. This tells me you have no standby voltage. Good luck and let me know how you make out

CHERYL42 inch digital lifestyles tv " FA2B-42570. THE TV WILL NOT TURN ON., what do i do?


if your FA2B-42570 does not power on that could be because of one out of two reasons: bad power board or bad main board.

Here is a link which will help you isolate the first case by basically telling you how to command the power board manually and checking if it produces what it needs to produce:

http://blog.coppelltvrepair.com/2012/10/testing-tom277cabb-for-digital.html

if it does, then the only other possibility left is the main board.

Also note that this TV is known to have inverters that fail over time, i.e. the TV actually works, but you can't see image on the screen because the light source behind the color filters that the LCD is made of is simply missing.

TV was unplugged for a little while and now won't power up and is making a buzzing sound. What can cause this?


How old is the tv? This is a power supply symptom. You will need to take the back of the tv off and check for puffed capacitors on the power pcb. This is the board where the power cord plugs into. Lay tv face down on a cushioned surface large enough to support the tv frame. You do not want to damage the panel. Then remove the back. If there are puffed capacitors, replace them with equal or slightly higher valued capacitors. The value rating for capacitors are mf and voltage, printed on the capacitors. If they look good, you will need to check the dc voltage output from the pcb usually about three connectors in the same area. One way or another, it is a power supply problem, usually corrected by replacing caps, but if that doesn't work, you will need to replace power pcb

Rca model d52w19 turns on and off three times then you have to try it agin. Sometimes it stays on somtimes it dosnt.


These units are famous for bad capacitors in the power supply and loose connections around the high voltage transformer. There are four capacitors in the power supply that will be bulged out on the top. They are towards the front of the power supply PCB. You have to remove the PCB in order to change these and repair the loose connections at the transformer. Cap values are marked on the components. Hope this helps. Thanks
