What type of remote would help?

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. /

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, or the LED light stationery; the main board is faulty.

Hello Collin, the problem that you will have that the replacement strips correspond to a lower screen size, you could have less illuminated areas, another problem would be the work tension, surely the 42 "strips have less LED than the 47, therefore the strip of 42 "would be working with a feed voltage calculated for the 47"
I suggest you try to get the strips for the measure 47 ", change them all, they are new, because for this work you must remove the LCD panel, very fragile element
I hope you can solve the problem
Greetings Franco Dosil

Hola Collin, el problema que vas a tener que las tiras de reemplazo corresponden a una medida de pantalla inferior, podrias tener zonas menos iluminadas, otro problema seria la tension de trabajo, seguramente las tiras de 42" tienen menos LED que la de 47, por lo tanto la tira de 42" estarian trabajando con una tension de alimentacion calculada para la de 47"
Te sugiero trates de conseguir las tiras para la medida 47", cambialas todas, que sean nuevas, porque para este trabajo debes retirar el panel LCD, elemento muy fragil
Espero puedas resolver el problema
Saludos Franco Dosil
