Question about RCA 27V530T 27" TV
Need some help. i am fixing a tv for my in-serve training. the problem is when i put the TV on spark come out of the flyback and blow the fuse. need to know how to fix that.
If fly-back transformer gets sparks, no doubt, the horizontal output transistor will blow out, at the instance you switch ON the set. If you wish to get more details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic / Time slide, can be selected by the drop-down list, at the top left of the display window, will make surf easy. You can also do a search, by type in the brand name/model number/IC used, in the search box at the top right of the display window. I think the site will help you like people so much. Good luck.

SOURCE: fuse blowout
Every time you put in that fuse and it sparks your probably causing more circuit damage as a fuse very very rarly goes bad for no reason.. Ok to the subject at hand. it you put back in a good fuse WITHOUT PLUGGING IN!! Next measure with an olm meter across the two legs on the plug on the end of the wire(the part you normally plug in.) Is there a short circuit?? yes? I would then start trouble shooting the front end of your main power supply like bridge recifyers,main b+ capacitor, the capacitor that goes across the ac line input as well as an VDR can short out in a surge. Now if that dosent get you anywhere your gonna need a schematic diagram. You can get that from howard sams photo facts. It available on line as a PDF for about 27.50. If you dont know what Im saying here then I really cant help you any farther and you will need to take the set to a quilified repair person as a tv even unplugged can hold 100's of volts. Now if you do know what your doing with solid state repairs by all means get the schematic and post it here for us to look at and we can assist you with this repair. Good Luck

Definate flyback problem or in that area of HV circuit start-up. Would leave it to the warranty to repair, they will just swap the entire supply.

SOURCE: RCA F32650 32" TV Problem:
The flyback is a a block with some wires coming from it. One of the wire is a big red wire that goes to the picture tube. The FBT is usually on the right rear of the circuit board.
Please be careful when working around the FBT as there are extremely high voltages present - in excess of 25K.
I would suggest you take it to a service shop as when the FBT goes, other parts are usually gone too.
