Do not remove the rear panel with the power cord still plugged in on your model or you will instantly wipe out the digital circuits. Its a safety feature. remove the front speaker grille screws are on the side and inside the door under power button. Then after you remove the speaker grille remove the small access panel and you will see the convergence board on the right side thre are 3 wire plugs on the right side of the convergence board. Un plug thos 3 wire plugs and try to power up the set if it powers up the problem is convergence. If it doesnt its the deflection. If you need the deflection board go to the following link they have one.

I have a sharp aquos tv model lc-32m400x. When i turn the power on via button at the back the green light comes on for about 10secs then turns to red and flashes about every 11/2 - 2secs. Any ideas.


Those 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.

If blinks continue without any pause, the main board is faulty.

I have a rca model led65g55r120q tv flickers and no sound


Check all cables for loose connection, try another input for picture (DVD, BLu-Ray, etc). If none of the other inputs work then it's a panel problem (display) If one or more of the others work then it's a problem with either the tuner or the signal.

I have sound but no picture on my tv


This is a popular question. Most of the time you either need to make sure all connections are not loose or just need to turn off your tv and receiver and unplug. Wait for 1 minute then reboot.
I recommend this short video as it walks you through some diagnostics for other possible problems.
