Interior lights and the power door locks are controlled by a electronic control module . Hooking up a factory or some other type professional scan tool an checking for codes an viewing input data to these control modules would be the first thing to do.
The interior lighting system consists of the following:
lighting control module (LCM)
driver door module (DDM)
instrument panel
dome/map combination
courtesy/reading lamps
orientation light
door lamps
footwell lamps
luggage compartment lamp
glove compartment lamp
vanity mirrors
door ajar switches
viewing wiring diagrams an checking power and ground circuits for these modules would be the next step if no codes were found . Principles of Operation
Lighting Control Module
This vehicle uses a lighting control module (LCM). The LCM is a microprocessor-based module that controls several vehicle subsystems, responds to electrical input signals from various switches, sensors, and external modules and is located on the LH side of the instrument panel. LCM subsystem functions include:
headlamps with autolamps
turn signal lamps/hazard flasher lamps
cornering lamps
parking lamps
daytime running lamps
interior lamps
demand lamps
battery saver
The LCM interfaces with the driver door module (DDM) via the standard corporate protocol (SCP) network for the illuminated entry feature.
The interior lamp is illuminated by pressing the individual interior lamp switch. The interior lamp is also illuminated by door ajar switches located in the door latches, when any door is opened. A theater lighting feature gradually increases or decreases the light intensity when switched by opening or closing a door.
The dome/map lamp combination are located on each side of the interior lamp. The map lamps are operated independently of the interior lamp by two switches located on the interior lamps.
The interior lamps are illuminated by holding the panel dim switch in the UP position until the dome lamps turn on. The interior lamp also illuminates when a door is opened and actuates the door ajar warning lamp switch in the door latch.
The front map lamps are powered by the demand lighting circuit and the interior lighting circuit.
The rear passenger reading lamps are incorporated into the rear seat assist handle and are located over the rear door openings. These lamps are illuminated through power supplied by the LCM demand lighting circuit.
Interior lamps (controlled by the LCM) are activated by using the dome lamp switch (instant ON/OFF response) or when a door is ajar. The following lamps illuminate for interior lighting:
instrument panel interior lamps
front map lamps
rear reading lamps
door lamps
Demand lighting includes lamps that are illuminated by the customer by directly actuating a switch. The front dome/map lamps are located in the overhead console. Each lamp is controlled by its own switch.
The following demand lamps are powered by the demand lighting output of the LCM:
glove compartment lamp
vanity mirror lamp
luggage compartment lamp
Each lamp has a dedicated switch that closes to ground to illuminate the lamp.
The front map lamps are powered by either the demand lighting circuit or the interior lighting circuit, depending upon the position of the switch associated with each lamp. When the customer turns the front map lamp switch ON, the front map lamp is illuminated through power supplied by the LCM demand lighting circuit. If the customer moves the map lamp switch to the OFF position, the power from the LCM demand lighting circuit is interrupted and the lamp is reconnected to the interior lighting circuit.
The rear reading lamps are powered by either the interior lighting circuit or the demand lighting circuit.
The luggage compartment lamp is controlled by the trunk ajar switch, and is powered by the demand lighting output from the LCM, and is mounted near the center of the upper rear panel.
The glove compartment lamp system consists of a glove compartment lamp switch and wire and miniature bulb assembly. Opening the glove compartment door closes the switch which provides power to the glove compartment lamp switch and wire. The glove compartment lamp switch is grounded to the body sheet metal.
The vanity mirror lamp system consists of a switch and bulb assembly in the RH inside visor and the LH inside visor. Lifting the vanity mirror cover closes the vanity mirror lamp switch and provides power to the lamps.
The illuminated entry system is controlled by the LCM and provides interior lighting upon entry to the vehicle.
Interior lamps will be illuminated for 25 (±1) seconds which includes a theater lighting ramp-up time (0.5 seconds). This time interval does not include the theater lighting ramp-down time. Interior lamps will be turned off before the 25 (±1)-second timeout if the ignition switch is turned to the RUN or ACC position.
The illuminated entry system has the following additions to accommodate the remote entry system: pressing the unlock button on the remote transmitter will activate the illuminated entry system (with theater ramp-up). When the driver door module detects a button press, it sends a signal on the J1850 communication network activating the interior lamps. The lighting control module will turn off the lamps by sensing the all doors lock signal.
The battery saver feature prevents excessive drain from loads inadvertently left on. When the ignition switch is turned OFF, power is interrupted to the interior lamps and headlamps (after a 10-minute timeout) and the demand lamps (after a 30-minute timeout).
The battery saver has the following inputs:

blinking yellow indicates no lamp or the lamp door is open. if you had the back off you may have gotten the door switch aligned improperly. the door switch is located just inside the lamp door.
the lamp may also be bad.
I'm sorry for the difficulties you're experiencing in locating the lamp door of the TV. The Lamp door is located on the right side of the TV. I'm providing a photo with Lamp door is marked. Please review the below picture.
Thanks for understanding. Please let me know if you require further assistance.
LAMP DOOR LOCATED IN THE BACK ON THE RIGHT HAND SIDE LOOKING FROM THE BACK. IT IS HELD ON BY 2 SCREWS THE LAMP IS SET BACK IN THE TV ABOUT 5 INCHES FROM THE LAMP DOOR SUGGEST A LONG FLAT HEAD SCREWDRIVER TO LOOSEN THE LAMP. INSERT NEW LAMP AND PUT LAMP DOOR BACK ON. THERE ARE INSTRUCTIONS IN YOUR OWNERS MANUAL.
Lamp door is not attached properly (all the way) or lamp door switch is bad (less probable case). Remove lamp door. Locate pin that pushes into lamp door switch. Figure out where it pushes, find switch lever over there. Check if it's broken. Than re-install lamp door carefully and secure with attached screw. Make sure also that lamp door is not melted/deformed in any way. If yes - it's got to be replaced with new one. Regards. Russ.
Unplug the TV. Locate the lamp door on the back of the TV. Take out the 4 screws and remove the lamp door. Remove the screw holding in the lamp. Locate the handles on the lamp and pull it out. Clear any wires that may get in the way as you remove it. Reverse process for installation. Make sure you do not touch the bulb, skin oils will damage it. Also, some models need to have the bottom of the lamp door be installed first, the top of the door will then swing unward... as if hinged. The reason for this is to properly engage the lamp door safety switch (the little blue level on the left). This is only some models, if your door does not install in this fashion, just push it straight in. I hope this helps.
The lamp is located behind the lower removable speaker grill on the front of the TV. There will be a lamp door then the lamp is up inside the TV behind the lamp door. Make sure the lamp door is back in place before turning on the TV after replacing the lamp as the set will not work without it installed.
Hi, there is no lamp door and it doesnt have a lamp neither since your tv is a CRT (Cathodic Ray Tube), only DLP's and LCD Projection TV's, For this issue you will really need to consult it with a Repair Center, CRT's are very frindly to fix, and it could be a issue on a small component if it is it will be very cheap to fix.
First unplug the AC feeding the set look in your owners manual for location of lamp door cover you may need a flat head screw driver. After locating the door and lamp it is just remove old lamp and firmly install new one do not get finger smudges on new lamp or try LG for help on line an online search for their customer website there you should find instructions to replace lamp
