Re: RCA D52W20 52 Fuse problem
Well you could always use a bigger fuse but I would not advise to do it, it could and most likely will blow tv not fuse. Fuses ussually blow from a short or power surge. If it is new or under warranty I would return it for replacement or repair.

you need to replace DL231, FL231 and CL230 all at the same time then resolder the flyback and vertical IC, You can get the parts under the RCA category at the following link, and they provide instructions on how to do the repair. http://servicemanuals.vstore.ca/
you need to replace 3 items FL231, DL231, CL230 then resolder the vertical IC and flyback conections. You can get the three components under the RCA parts category at this link. http://servicemanuals.vstore.ca/
I am assuming that you preplaced the flyback and horizontal out together. Even if you did, was it blowing fuses before? Usually with this chassis, the horizontal will not blow the fuse. It will just keep the swith mode power supply from operating. Double check and make sure you didn't have a soldered blob get away from the iron and "splash" somewhere on the board
Most likely there was a power event (surge, brownout, ect) that caused the power supply to fail in the TV causing the fuse to blow. you will need to have someone come and look at the unit and give you an estimate. If you keep putting fuses in and blowing them you could actually be causing more damage.
