I thought I e-mailed you last Sunday but I don't find anything. Okay, here is the deal my husband replaced the fuse for the 5th time and this time he soldered the flyback, last Friday. Worked all weekend went to put the cover back on Sunday afternoon. And it started doing it thing of kicking off and on with no picture. We tried resoldering the flyback again and we still can't get any power. Please help I just hate to ditch this TV. It has to be fixable. I'm not willing to give up.

Re: hd52w59 - Me again....
Sorry havent got back got some personal issue going on. So its cycling off. my fist instinct is to check the ribbion cables that go between boards. and most connectors. theres a cable that runs from the back green booard to the front center crt board in the front. this could be a problem. does the set make any noises?

If you replace just the fl231 it will blow again. You will need to replace the FL231,DL231 and CP230. You can get the parts at the following link with free instructions with pictures total cost is about 12.00 shipping is free. the parts are all listed under the RCA parts category. http://servicemanuals.vstore.ca/
the flyback transformer is the large black component simalar looking to a disrtibitor of a car it has a large red wire coming out of top and a black wire. On the bottom of the board it has about 10 pins arranged in a circle. this is flyback is located adjacent to the fuse.
OK those are the correct fuses one in middle does cause lost of convergence FL231,recheck second ribbon connector, make sure it is in correctly also ck cp 150 it will be a green and gold writing on capacitor 2200uf 16v ,see if it is bubbled on top if so replace it and 2 other caps 220uf 35v,what you are saying about it waving could be a big capacitor on small AC board where ac fuse and cord plugs into ck them .Let me know if you need more help . Resolder all connection pinns on flyback.
nice obsrervation! lead free solder this half circle is it directly under the big black componet with the red wire. i not familer with the notation cad. but the circle is charteristic of flyback. This is the common point that cause the fl231 fuse to blow.i would suggest removing the solder with a ****** or wick the clean and reappy solder when you replace fuse. always look around for bad connections like this. lead free is really become a problem with rca
you need to have the conversion chips replaced , this is a pretty common repair and i would say it is definately worth the fix, some repair shops will come and fix it within a half hour to an hour depending on the difficulty in taking out the old part and or putting in the new
DId you solder the flyback transformer connections..... This is the main reason these fuses fail. THe flyback is the big black component next to the fuse. poor solder connection cause oscillations.. this fuse is only .4 amps whish dosent stand up to that well.. resolder these pins on the flyback.... the first time i replaced this fuse i failed to solder played well for 2 days then came back blown again
Before you go and buy parts it might be worth your time to check the convergence power supply fuse. It's located in the back of the TV just to the right of a large black component with 2 red wires coming off of the top. This is the flyback transformer. Just to the right of the flyback you should see three fuseable links that look like chicklet's gum. The one that may have fried is the one in the middle, it's a 400mA 125V fuseable link. Hopefully thats all your problem is.
