Question about Projection Televisions
I have a r52wh74 rca tv and I just turned it on and I have 3 colored lines at the top and it looks like it is in 3d. How do I replace the fl231 fuse and repair the flyback transformer and where are they located?
I'm sorry, but you have no idea what you're doing. STOP!!!!! What makes you think the fly is bad? A bad fly will not let the set come on at all. If it was me, I'd be thinking the convergance circuit. That's why you have the 3D picture. If you hell bent on your diagnostic, The flyback is the most recognizable part inside a television. It's big, It's plastic and it has a big red spark-plug looking wire coming out the top. You unsolder it from the bottom. RadioShack has a desoldering iron with a red bulb that works great. Also some solder wick. Unsolder the pins and remove. Then replace and resolder. Same thing with the fuse. The fuses are all marked on the circuit board itself. Any part on the board must be removed by unsoldering. You need to trouble shoot in a better way than you are or you'll be spending alot of money you don't need to. Also, if you don't know what your doing, you can get yourself into trouble real fast and make the set unrepairable. Most shops won't work on sets that the customer tried to fix themself. You got me VERY worried. You are the guys I worry about giving information too and wind up killing themself. Please....get some help with that thing. I just don't want you getting hurt or destroying your T.V. It's an easy fix right now, but you have to know what you're doing.
