Check for shorted horizontal output or one of the low voltage regulators being shorted. Must remove from circuit to check for shorts

How many amps is the fuse that is located on the back of the TV near the power cord. It says T5AL/125 or 250 v. f800


Something else is going on to cause the fuse to keep blowing. Sounds like you have an issue on your power supply in the unit. Also check the outlet that your plugging it in to. Good luck!

My fuse keeps blowing when i plug the tv in. It was working fine and then just blew a fuse. Now every time i put in a new one, it blows instantly when plugged in.


That could be caused by either the AC main filter board ( Most Likliest) or also the deflection board. You can get replacement boards from www.tvrepairworld.com and free assistance to help determine which board has the issue.

Keeps blowing fuse


You will probably be replacing boards left and right with a surge. I would make a claim with the insurance company, it's covered under most home owner's insurance.

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.

Blown fuse


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.
