No picture. Power's up, can hear sound but no picture. change to other input's same results. Can not pull up any visual image

Sounds like main board issues

your projection bulb needs replacement i think...if i got you clearly!

sounds more like the video control board to me. You'll find that video drive is fundamental reason why these go 'black'

Cant read the model number but this is most likely the back light and depending on the model it could be LED strings or power supply.

Fault at its main digital 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.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Can you hear sound? Is power light on? Where did the smoke come from?

U have sound but no picture?Picture does flashes a few sec?Yes,than those 2 long LCD inverter boards are dead.Tries websites like Shopjimmy.com,Ebay.com to buy those 2 long LCD inverter boards for the replacement.

Your inverter circuits and/or power board need servicing.....

Either three fault scenarios are happening:

1. the inverter circuits are not producing AC ripple too the CCFL lamps that illuminate the LCD glass panel.

2. the power supply board is not feeding 24vdc - 12vdc sustain voltage too the inverter circuits. Meaning, no dc high voltage output from the power board.

3. The timing control circuit (LCD Board) has shorted switching devices or on-board memory has failed....which causes data/dc loss at the input which results in the inverters canceling load power (lamps). The sync data between inverter and LCD Board are absent. This will result in a 'NO LIGHT' condition on the LCD display.

Number 3 is a rare case, its usually #1 the inverters need servicing.....
