To know more about this, you have to download the repair manual to this set by internet. It has all details. If you wish to get some more details, check this link. Selecting the view option, either to Mosaic / Time slide, can be selected by the drop-down list, at the top left of the display window, will make surf easy. You can also do a search, by type in the brand name/model number/IC used, in the search box at the top right of the display window.

If you are working in the switching power supply and need electrolytic, I would use PANASONIC FM series for very low ESR, High ripple current rating, 105c temp. Get them from

LG TV Model 32CS460 black screen power light is red, then flashes if you push the tv button.

Have you checked the output voltages on your power supply. If they are good and depending on what type of set you have it could be the logic or t-con board. Your set is in stand by mode put there because the diagnostic circuits have deteted a problem some where in the circuits and will not let it power up fully to prevent damage to other circuits. Disconnect all leads from your power board and check out put voltages. Their value is stamped on the board next to each pin, if these check good move on to a logic board( if equipped) and them to the t-con board.. I am thinking you have problems on your power board. Capacitors are the least of things that can go out on that power board.

I have a LG 26 in. flat panel, and today when I pressed the power button on the remote, the red light on the front of the tv just blinks continously, and will not connect the tv. please help....

A lot of times this is traceable back to the power supply board in the TV. Open up the back and look for swollen or leaking capacitors on the board (distinguishable many times by the very large cooling piece and the largest capacitors.) Swollen caps can lead to very random problems, even protection shut downs to prevent further damage to the TV. You will only be able to get the parts from a smaller authorized LG retail store, and even then they will probably suggest to you to let them take a look at it to verify. Go in with either the TV or model and serial if you do decide to.

It has not the C405 capacitor

if your are a technician , you will be able to do that.
remove the back, carefully remove the main board, plug the tv. with the multimeter on DC voltage, check the voltage at that point . If you find a 10V , the capacitor will be 16V, if 12V the capacitor will be 25V. in general the capacitor have to be electrolytic and have more than 470microfard.
