Remote controler How do I set the sleeper on my remote control

Hi, I could not find the user manual of your JVC LT-40DG52J, you should have the TV a way to enter the menu and make the changes you need
What if I have found a sale publication of the replacement of the remote control of your JVC
I give you the link to download it
I hope you can get the remote control or solve the problem
Greetings Franco Dosil

Set-up (Programming) procedure is too much to type in here, and is not practical and it will differ brand-to-brand remote controls. If you wish to get more; check the sites linked here. It has set-up code list & set-up procedure to many popular brand remote controls. One among it has general set-up codes to check with TVs and other devices are given, in the order of the 'device's brand name list' in alphabetical order. Pull up older posts. Search the sites by type in the brand name to your device in its search box at the top right part of the display window. It will help you to find the document easily.

Programming Notes
• If your device does not respond to the remote after trying all codes listed or your brand is not listed in the code list, use the Auto Code Search method to program your remote.
• Sometimes the first code that "works" with your device may operate only a few functions of your device. There may be another code in the code list that performs more functions. Try other codes from the code list for more functionality.
This is a trial and error procedure; and quiet time consuming. You might have to check different codes said for your device.

Sounds like no power to it. Check the breaker or fuse. Connector may have vibrated loose. If it has a wireless remote, change the batteries in the remote. Good luck.

It will best to buy a remote control for TV, rather than try to repair this remote control. Sometimes, after repair, it won't work with Blu-ray; and it will be difficult to get a universal remote control for blue-ray. If you wish to buy its original remote control, contact the authorized service center, or authorized dealer to your device brand.
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 you have.
Please note: Every new universal remote control will have set-up code list, and set-up procedure along with its user manual. Never accept a remote control, that hasn't both of this. If you see the site by "MOSAIC" view, will make surf easier.
