Only Rt turn signal works no matter if switch is in Lt or Rt position


The multi-function switch could be defective. The L/R position signals go to the instrument cluster then they are bussed on computer data lines to the front control module to develop the outputs that light the turn lamps. The defect could be in the instrument cluster, the front control module, or even the PCM

Turn Signal Lamps
The LT T/SIG and RT T/SIG fuses located in the underhood fuse block supplies battery positive voltage to the body control module (BCM) for turn signal and hazard lamp operation. When the turn signal switch is place in either the LEFT or RIGHT position, ground from G202 is applied through the turn signal switch signal circuit to the BCM indicating the turn signal request. In response to this signal, the BCM applies a pulsating voltage to the front and rear turn signal lamps supply voltage circuits cycling the lamps ON and OFF. The BCM also sends a message via GMLAN to the instrument panel cluster (IPC) to cycle the turn signal indicator ON and OFF depending on the position of the turn signal switch.
Ground for the turn signal lamps is supplied as follows:
• G101 provides ground for the left front turn signal lamp
• G100 provides ground for the right front turn signal lamp
• G302 provides ground for the left and right rear turn signal lamps

The LT T/SIG and RT T/SIG fuses located in the underhood fuse block are also used by the body control module (BCM) for stop lamp operation.
The brake pedal position sensor is used to sense the action of the driver application of the brake pedal. The body control module (BCM) provides both, a 5-volt reference voltage and low reference to the brake pedal position sensor. The position sensor provides an analog voltage signal back to the BCM that will increase as the brake pedal is applied. When the brake pedal is applied, the BCM will then apply battery voltage to the left and right stop lamp supply voltage circuits and the center high mounted stop lamp (CHMSL) supply voltage circuit illuminating the stop lamps. At the same time the BCM signals the transmission control module (TCM) and the engine control module (ECM) that the brakes are applied. Ground for all stop lamps is provided at G302.
The stop lamps on this vehicle will not illuminate unless the ignition is in the accessory, run, or crank positions. When the ignition is in the OFF position the stop lamps will not illuminate when the brake pedal is applied.

Did you check the fuse's. ? Wouldn't think it's a ground because right an left tail lamp Assembly's use same ground ! Did you check for B+ voltage at the bulb. with a volt meter ? Power is supplied by the BCM . Could be the tail lamp assembly

I have an LG DLP. that turns off after 15 -30 seconds


If the second light is blinking to orange or red, that is usually the lamp indicator light on an LG DLP tv. That indicates your bulb needs replaced, or something surrounding the bulb has failed (like the cooling fan for the bulb for example) IF you have a spare bulb handy, I'd replace the bulb, keeping in mind if you touch any part of a new bulb with your bare hands, you just cut the life of the bulb by more then half.

How Do I Reset the lamp Timer?


I have replaced many lamps in LG TV's and have NEVER heard that. The lamp is meant to be replaced by the consumer but the timer on LG's is ONLY resettable by a special service remote that technicians usually have. The timer has no effect on the voltage to the lamp.

LG Rear Projection 44" will not turn on


Make sure you reinstall the lamp door as there is a lamp door switch that must be closed or the unit will not fire the lamp, there should be a small hole or opening on lamp door housing. Some people install the lamp without reclosing the door just to see if the unit works , just to find out if it will not work, and when it does;nt think something is wrong, they do not put the lamp door back on first. Not to say this is the case but it does happen.

Mu bulb has blown on my LG rear projection tV model RT-52SZ60DB


The hours reset procedure is outlined in the owner's manual. Also, the lamp usually includes these instructions as well. If you could post the model number, I should be able to get you that procedure. Also, why are you replacing the lamp? Is there a problem? These should only be replaced when required. They are not cheap. Also, when replacing the lamp, make sure that the access door is seated properly or the set won't turn on. There are safety interlocks that prevent the set from turning on if a door is open.

RT-49NZ21RB


hi my lg projection tv model RT-49NZ21RB suddenly went dead while we are using it. The fuse seems to be OK and whenever I turned on the tv, there was a short high pitch noise but no audio/ video. I am not familiar with the projection TV, would it be the lamps but my best guess is it is not the lamps because there are three of them. Please help. Thanks.
