LG TV Hidden Service Menu

The following is a large collection of community notes compiled from a long forum thread — kept here as an unformatted reference for advanced tweaking.

EZmenu note: to accomplish this on my TV I used my Brighthouse remote and used the info from the Radio Shack remote — just changed 9-9-4 to 0056 to match my remote per their instructions.

Don't brick your TV — be conservative and don't change anything you don't fully understand.

What is this Secret Hidden Menu (EZMenu)? In a nutshell, there's a hidden menu that lets the LG factory turn features on and off using a 1 or 0 value. Quite a few LG TVs can perform some higher-end model functions because the architecture is almost identical. There is risk — but it's like overclocking a PC: only turn on features you've seen others discussing for your particular model number and you'll be fine.

All LG service techs have a specialized remote to access this menu. You can buy one, or use a cheap universal/Harmony remote configured with the "Poor Man's Service Remote" procedure (search openlgtv.org.ru wiki: "Access hidden service menus / modes").

Example — turning a 47LW5700 into a 47LW5600 (local dimming): Password = 0413 or 0000 (use the original remote to navigate and enter values).

• Option 1 → Tool → change to LW56 (fools the set into thinking it's a LW5600)
• Option 2 → LocalDim Menu = 1 (turns on the menu item)
• Option 4 → Local Dimming = 1

After any change, exit the menu, wait 10 seconds, power off the TV, wait 20 seconds, then power back on.

Other cool tweaks:

• Option 3 → THX & ISF setting = 1 (adds THX & ISF video modes; not available on DLNA/MediaLink)
• Option 5 → Channel Browser = 1 (preview thumbnail grid of all channels; may not work on US cable)
• Option 5 or 6 (model-dependent) → 3D THX = 1

Word to the wise: do NOT select THX Media Director on any LCD TV — it can destabilize the TV; it's meant for plasma (PDP).

3D starting-point picture settings: Picture mode Standard, Backlight 80, Contrast 100, Brightness 50, Sharpness 50, Color 55, Tint 0, Color Temp 0, Dynamic Contrast Medium, Dynamic Color High, Clear White Off, Skin Color 0, Noise Reduction Low, Super Resolution On, MPEG NR Low, Gamma Medium, Black Level Low, Eye Care Off, Real Cinema On, Color Gamut Wide, TruMotion Off, LED Local Dimming Medium, Energy Saving Off. Backlight is the key for day/night: Night ≈ 28, Day ≈ 80–90.

2D expert settings: Energy Saving Off, Picture Mode Expert1, Backlight 28, Contrast 89, Brightness 52, H/V Sharpness 50, Color 50, Tint 0. Expert control: Dynamic Contrast Off, Noise Reduction Off, MPEG NR Off, Super Resolution Off, Black Level Low, Real Cinema On, Color Gamut BT709, Edge Enhancer Off, Color Temp Warm, Gamma 2.2. 2-point white balance: Contrast R -6 G 0 B -34, Brightness R 2 G 0 B 1. 10-point at 20/30/90/100 IRE and CMS values are listed in the original thread.

Sound / AC3: LG doesn't pay DTS licensing, so DTS is blocked — but AC3 / Dolby Digital can be passed through. In the EZ Adjust menu, scroll to "AC3 EDID D/L" and press select, then Start — it sequentially enables AC3 on each input. When it says "OK", exit, wait 10s, power off, wait 20s, power on. If you get lip-sync issues over optical, try the audio-sync option, or the "erase to NG then re-write with all cables unplugged" fix from the thread.

Roll back firmware (standard remote): Home → Setup → highlight the Option menu (toolkit icon) → press 9 six times. It automatically rolls back and reboots.

DVR: This TV has built-in DVR functionality — you just supply an external USB drive. Option 3 → DVR Ready = 1 enables Time Machine. Plug the drive into USB port 1, decline the "use it" prompt, go to the home screen, open the Time Machine app, and initialize/format the drive. HDMI sources may prohibit recording; the DVR feature is officially enabled only for certain country codes (FI, SV, N, DK, ES, RU, UA, KZ, LT, EE, LV, CZ) — changing the country/group to bypass the HDMI restriction can brick the TV.

General: Real Cinema is not available for progressive-scan content.
