There's a weak capacitor on the power board. Look for a bulged or leaky capacitor and replace it, or change the entire board.

The three blink error code is a standby power problem. Get your volt meter out and check the voltages from the power supply to the TV board. Standby power is 3.3v or 5v. If you have standby power on the power board that means replace the main TV board.

That clicking sound is the safety relay not clicking in to protect the TV from frying out. The problem is most likely the power board.

You need all 3 jacks plug in. If there is no video feed the input will not work. To fix this plug your LG radio into a VCR input (video not needed ) then plug all three from the VCR to your TV AV input.

Check the voltages going to the TV main board first. If they are all good, replace the main TV board. That;s where the problem is.

Without a remote control, you can't. If you wish to buy its original remote control, contact the authorized service centre, or authorized dealer to your device brand. They can either give you a genuine remote control to your device, or can direct you, from where can you purchase a suitable one.
To select a proper universal remote control, you should know about the number of digits to its set-up codes. There are 3 digit, 4 digit, 5 digit, 2 digit and even single digit codes, to some brand devices. After confirming this, check the sites linked here. Both the sites have set-up code list and set-up procedure to many popular brand remote controls. Check which brand remote control has set-up code/s to your device brand, and buy that one according to availability. Brand name of the remote control isn't a matter, but it should have set-up codes in its code list, to the device brand you have.
Please note: Every new universal remote control will have set-up code list, and set-up procedure along with its pack. Never accept a remote control, that hasn't both of this. For more details about the set-up codes, visit the sites.

Universal remote controls are available at most of the electronic spare part selling shops. Visit some on-line sites too, which deals with electronic spare parts. /
