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.

Which pico? Its possible you have a convergence chip failure that is causing it to blow.

Problem #1) Convergence

Symptoms:

  • Screen Looks 3D
  • Colors wont align
  • Video may look distorted
Problem #2 CRT Fluid has clouded over. Symtoms
  • Dull looking video

Power problem on Pioneer Pro-700HD


The failure is not on the power supply but the convergence amplifiers STK ICs have the 24 volts shorted.
If that fuse is blowing, de-solder the convergence ICs and put a new fuse to power up the TV; you should see distorted video when the TV powers up and the fuse should not blow.
The service manual migth not help much in this case since the failure is easy to pin point.

Good Luck.

You most likely need a new convergence power supply board if fl231 keeps blowing thats the most likely cause, also check for shorthed capacitor cp231. If you need a link to get a replacement convergence power supply board, let me know I know where you can get them.

RCA HD52W59 Convergence issues after some repairs.


Hello rmolen,

This is an indication that the convergence amps are drawing too much current which has an effect on the power supply and thus killing your sound by removing or lowering the voltage supplied to that stage, finally this results in the blowing of the fuse. I would suggest that you change the convergence amplifiers and the biasing resistors (All of them) and then see if this corrects your problem (I believe it will). Also get a schematic of the TV and try to find out how the power supply relates the sound module and the convergence module, they might share a common power bus, or the voltage regulator for the sound also feeds the convergence board.

I hope this helps,

Thank you,

RCA R52WM24 52 in. HDTV convergence IC location


the rca itc222 chasis uses no stk the convergence is controled with transistors... the convergence amp board is located above the main signal board(green board)... it can be identified as the one with several heat sink fins on it. FL231 is related to convergence.. there has been a problem with this fuse when it blows the processor doesnt know it is a projection set so it turns it into a regular tube tv. Here at the shop we have found number one reason this fuse blows is poor solder connection on the flyback. So replace the fuse and reflow the solder connection on the flyback and around that area also the horizontal transistor and then see if that doesnt fix the problem.. if you have an more trouble ..... willie@fordtv.com
