    I have the same problem where the power clicks on, red light blinks 5 times then no picture or sound. Believe the caps to be the issue but not sure.

    How do I know what the problem really is???
    What test points should I check and what are the corresponding Voltage readings for those test points? The only schematics I found on-line here don't seem to match my board...

Are the capacators blown? If not, they actually are not the problem. They will still work, but you can probably find them at or

hi sounds like you have a faulty power supply board which could have faulty swollen capacitors that resemble little cans....replace the swollen ones with new ones which can be purchased from maplins RS spares online or ebay,,,,make sure you buy the same value(uf) and voltage which is written on the side of the capacitors and also make sure you put the in the right way round.
hope this helps

My lg flat screen 2008 model keeps turning on and off what do I do

probably needs to change some capacitors in the power entrance, because the lcd has worked much time or the current is very insable causing problems in the capacitors.
open the lcd and see in the power section if some of the round cilinders are round in the top, almost ready to explode. if so, change them for new ones whit the same especifications. Usually they are vey cheap.

After recording a programme last night on my thomson freeview box a flashing orange light came on. i have tried switching it off at the plug, but the flashing light is still there

Hi, a common problem with the thomson freeview boxes is capacitors leaking in the power supply, The ones that go usually are the two 1000uf capacitors. If any of the capacitors look deformed, ie the tops look domed in any way. I would change them , Handy if you know how to use a soldering iron. If you can use a soldering iron remember to put the new capacitor in the same way ( the wires are marked so you must put them in the same way round).

What are the locations for the capacitors on the LN26A330 power supply circuit board? What capacitors go in what location.

All the capacitors will have location numbers printed on the bottom and top of the circuit board next to them like C18 etc--the values of each will be printed on each capacitor--as well as one side of each will have a strip with - which means it is the negative side of the cap and the other side will be the + or positive side--look for ones that are puffed up on top---see attached photo of a new and good cap--the silver top with the creases should be perfectly flat.

Any bad ones should be visible to the naked eye.

Let me know what you find---if you find puffed up ones they will be marked also with a value like 1000 mfd (microfarad) at 10 v (means the cap is rated at 10 volts.)

If you find bad ones it is a good idea to replace with a higher voltage rated cap of the same value--it may present a small problem as the higher the voltage rating is the bigger the part will be.

The reason (if you have puffed up ones) they fail is because too low a voltage rated cap was used when the set was made---saves the company who makes the sets a few cents on each part.

Let me know if you have questions of need advice.



note the gray band on the left side--negative lead (each has 2 leads) is indicated that way.

When I try to turn on our relatively new Samsung flat screen TV, it clicks off/on, off/on numerous times before actually turning on and staying on. Any ideas what could be causing this?

A lot of these Samsung LCD and Plasma TV's used marginal electrolytic capacitors in the power supply. You can usually tell which capactors are bad, because their tops will be swollen (rounded) instead of flat. The usual values of the bad capacitors are either 2200 uF or 3300 uF, usually rated at 35V, depending on the model. I've seen these capacitors go bad after just 1 year of use. It's a relatively easy repair for any qualified electronic or TV technician.
