Step i took replace blown 5amp 125v main fuse,tv power on but have bow at the top and bottom of screen,the picture image and quality of color is poor. image on screen is 2 dimentonal and red in color. took your advise and took set to a tv repair shop tech stated the convergence power supply board need replacing and this may not solve the problem!would cost 600.00 to replace the convergence supply board. caught in the middle i not sure paying 600.00 to replace the supply board and it may not solve the problem is fiscalable.need second opinion.
Replace the Sanyo I.C. Chip on the convergence power supply board. Cost you about $5.00. You are getting stiffed for $600. It is not necessary to replace the whole board. Fact is they just repair/recycle the boards anyway. It's a racket. Any good TV Technician should do it for $100 and still make a killing. You can buy the part here.
Your convergence module is probably bad.
It is a plug in module, so labor would be lower if the convergence settings are still good. The bill would be about $300.00 If not, the labor for convergence would add to the bill. If the whole job needed full convergence the cost would be about $500 to $600.
Hope this helps,

All telivisions are provided with fuses, and the function of fuse is to protect its internal circuit agains short circuit, and protect the other components in the TV. if fuse must blow, surely there must ba reason. Without rectify that reason, if you put the fuse and switch it again, it may poise to other more problems. So get it repaired with a qulaified service personal. Never put any more fuse in it and swich on the Tv. Ok.
Open the television and follow the power cord to the main power supply board the fuse will be near this cords contact plug check for blown 5amp fuse, if fuse is not blown then power supply took a shock and needs repair.
Go to Menu then to setup if you do not see Convergence in the menu then you have a blowed Fuse FL231 it will be on right hand side of FBT flyback Transfomer there is 3 in a roll it will be the Middle one they are small brown rectrangler Looking caps but are Fuses Located on the Deflection board Bottom Left hand Board.
You will need to remove the back of the TV. Don't worry, it's not that bad.
There are 4 screws across the top, one on each side, one right next to
where the power cord goes into the back of the case, and the two more
by all of the video connections **These are the most important to
remove because they attach the main board to the back of the case.
Once you have remove the screws then the entire back of the set will
slide off. If you look where the power cord attaches to the board you
will see a small fuse. This is a 6.3 Amp 125 volt fuse. You can replace
it with a 6.3 Amp 250 volt fuse from your local Radio Shack. A four
pack costs between $3 and $5.
Make sure that you check that it works before putting it all back
together. Check for any loose connection cables while you're back
there. I found a few when I did this.
fl231 is the convergence fuse, and is soldered to the board in proximity of the convergence ICS, on RCA rear projection TVs.
If fl231 has blown, TV usually does not turn on at al, if you get bowed picture, that means that the convergence ICs must be replaced.
The fuse is on the same board where you find convergence ICs, if the fuse had blown, or the pico fuses at the base of the STK convergence ics had blown, the STKs must be replaced. There is need of purchasing the service manual to do the job.
If the convergence is missing in the menu in screens,you have a bad reg ic on the convergence power supply the part number is 215530,the power supply is located on the black plastic above the right module with all the heat sinks
