We purchased a white HD 1080P Home theatre LED Projector, we cannot get the sound to work. What could be the problem?

The AV may require a separate audio connection. For HDMI, check that resolution (720 vs 1080, etc.) are matched. Could be HDCP handshake failure. Sometimes this can be fixed by powering source & projector off, then back on. Sometimes it is incompatibility between devices, which some claim can be fixed with powered switches (but didn't in my case [with other brands]). HDCP is a bag of hurt.

Hi Ajin, I have a LG RD-JT52 Projector which I

HI David,
Sorry for the late replay first of all. I dont have the service manual with me. So i need the service manual for assist you. One more thing is You will not be able to connect the led directly to the power supply of your projector. For that you need Buck converter to connect in between the led and power supply. Normally leds are of voltage between 1.8V to 3V range. That will be mentioned in the PDF datasheet of the LED. The tearm BUCK means to reduce the voltage From the applied voltage to the range of LED working voltage. If not the led will burn out. You didnt mentioned about is the buck converter is there or not . If its there i want to know the input voltage range of the Buck converter. If it is not there, sent the service manual i will check out and tell you what type of buck converter you need. And how to replace with the LED if it possible. My email address is

Lens light not glow?

1) Does the projector have power? There should be at least 1 LED lit on the body. Make sure that the on/off switch is on and that the mains feed is working.

2) Turn the projector on. Does the fan run? Are there any error codes indicated? Consult the manual for help interpreting them.

It may be that you require a new lamp, however I would verify the projector is working and that the LEDS indicate this before spending any money on it.
