Question about Sanyo DP32746 32 in. LCD Television

1 Answer

My sanyo dp32746 clicks on, screen flashes, has sound but no pic

When I turn on my dp32746 I get sound & no picture. Upon opening up the unit I discovered one of the 2 fuses on the inverter bd blown. Further investigation led me to find Q19 was shorted. My problem is I cannot find the replacement # for this I.C. The only #'s I have are 4614 & BD6E3P it is an 8 pin SOIC surface mount I.C. The chip itself has an "A" symbol on it. Does anyone know the manufacturer or the prefex to 4614 of this SOIC. Thanks Tom

Hello, I just posted this to another user's question, and you might find it useful, too.

I have a pile of these in my shop. Unfortunately and usually, a backlight lamp is bad, and the inverter board is damaged when it goes out. The backlight lamps are sealed inside the panel, so the usual method of repair is to replace the panel.
If you turn the lights off in the room, then turn the tv on, you will probably see a momentary flash of light from the backlight trying to start up. The lamps can be replaced, but the option is not really cost effective given the amount of time it takes to replace them/very delicate nature of the lamps/availability of the lamps/cost of the lamps. Replacement panels might be available, but you'd have to use a TV shop for reference or call Sanyo directly.
These units also have a history of power supply heat damage, so if you don't see the momentary flash, it could be the power supply. But the momentary flash is the dead giveaway.

I hope this helps you...
