I hv got LCD TV hv No picture but have very good sound. While power put on ,it flash & go. What to do? This is for BenQ LCD TV 2680.Back light inverter is avllable? in case needed.


Hello
As you thinks mey correct to an extent. If backlight inverter board has some kind of short with its components, the fault you describes here will occur to LCD TVs, irrespective of Brand and Model. Most of the backlight inverters for any models are available at open electronic spare part shops at your town. Just take the backlight inverter board out from your Tv. It will have a special number printed on it, and should be noted when buying a new one. Remember its connections when you take the boaed out from your set. If needy, mark the positions of connecting wires to that borad on a piece of paper, for reference.
Replace the backlight inverter first. It must solve the problem of your BenQ LCD Tv. OK.

No picture


If we first establish if the tv has actually come on and out of standby. If this is the case, gently press on the lcd with your finger..Is there any backlight showing ? Is there any sound on the TV? If there is sound and no picture and no backlight your problem will be the invertor. If there is no sound, no backlight, the fault most probably is the power supply board, and could be a fuse or capacitors going 'dry' with bulging tops. If there is backlight and sound, the problem will most likely be main pcb or the Tcon pcb (mounted on the LCD rear top middle).

It sounds like the color wheel has gone bad and needs to be replaced. This is located behind the back panel... replacing a new colour wheel will solve ur problem
