Hi I pulled the blow fuse and went to radio shack to try and replace it no luck
The fuse says .6a/125v and P233
It has some symbol F. before the 6a not sure if this is . 6 or 6amp
could not find either one at radio shack any help with alternitive fuse ?

Re: RCA HDTV R52WH74YX61 blown fuse
There are 3 small red rectangular shape objects to the right of the flyback transformer these are fuses the fl231 most time goes bad .fl231 is the location number under the green circuit board. the location number can also be wriitten on top(brown side of the cicuit board) you may have to put back the .6a you took out was it ok?
TRITRONIC ELECTRONICS sell parts . cathray 416 241 1106 sells also

Either you have a dead short or you used the wrong fuse--not all 6a fuses are the same---buy a cheap generic one from Radio shack etc and it can blow for no reason.
If not the wrong fuse---the fuse you are talking about should be where power enters the set--means a short on primary side of set's power supply---somewhere between power cord and input side----possible the bridge rectifier is shorted.
l have usually seen this when there was a power outage or a surge on the incoming power line.
This DLP model RCA tv have convergence menu disappearing is very easy to fix just replaced the convergence fuse FL 231 near the FBT also must be resoldering FBT too.U can buy this FL231 covergence fuse at Ebay.com.No,but u must have to have a soldering iron,a desoring pump or desoldering braids and know how to basic soldering?To replaced this FL231 convergence fuse near the FBT and also must resodering the FBT too for protecting the new FL231 convergence fuse.
Over the years of servicing these sets and others for Convergence issues, I have on several times gotten defective Convergence ICs. In your case where a Resistor is now open, (Probably a 1.5 ohm 1/2 watt), I would suspect you had gotten a hold of a defective IC. I would replace them both again. Make sure to use Heat Sink Compound between the ICs and Heat Sink.(Just a thin coating on the metal area) You can get the heat sink compound from Radio Shack. They should also have the Resistor you need.
if the fuse you took out at first was fried black as cool, how do you know it was .6a
now the fl231 as I told you before is close to the flyback transformer
Go to google search -type in flyback transformer --enter
scroll down to get video results for flyback
click on the picture
now you will see what a flyback looks like
you should not try to fix tv if you have no idea of tv repair.it is very cmplicated and fatal .there is serious high voltage in tv sets
yes, thats the replacement fuse for your set. However unless you have replaced the convergence power supply also chances are the fuse will blow again, as the power supply shorting is what causes the convergence to get out of alignment and it will then blow FL231 thereby removing the convergence option from the menu.
If its the regular glass fuse, radio shack should have a replacement for that just bring the old fuse with you so you can get the correct amp fuse. If it blows again, let me know and I will try to assist you as usually fuses blow for a raeson. Please respond to this same post when replying.
Usually when the fuse blows its due to a component being shorted and if you increase the rating of the fuse you can cause other components in the circuit to blow. The pop you hear was most like a capacitor on the D board. The D board is no longer available from sony as its listed as discontinued. You will most likely have to have a qualified sony service tech trouble shoot the circuits on the D board to locate the short as it will be outside the scope of a do it yourself type of repair
you have a fusible link that has blown. This is what causes the convergence option no be erased from the menu. You will need to locate the blown link and replace it. They are identified by FLpreceeding the location number on the circuit board such FL221 and etc.
