Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

SOURCE: Red power light and buzzing sound with red lamp light.

If the lamp does not light at all, it is probably a bad lamp. The buzzing may be the ballast trying to start the lamp or a problem with the power supply. Check the lamp and see if the arc tube is broken. If its a new lamp, you should be under warranty. I have the manual if you want to go to me site at allprojectorlamps.com. Just send you email to me attention Bulb Guy

Model 32ld452c. Why is there a black screen and no sound?


Sounds like main digital board fault. These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
