rca convergence problem	Can't Post

i have a rca 52 in model D52w20b i think the chassi # is e176c301f.i recently had to fix the diaphragm on the blue crt lens. i fill the blue crt lens back up and put it back together. well while fixing the blue crt i broke the red crt kine drive. so i ordered a new one of those and replaced that.. put it all back together tried to set my convergence and now the red and bluce picture curves down on the left side of the t.v. why is it doing this.. it will not let me set the convergence because the green is straight but the red and blue curve the same way.. down on the bottom left of the screen.. also i tried to get to the service screen by holding the channel and volume buttons with the tv off. and my tv doesnt do any thing.. please help.. <br>

Just a couple thing to check:

Check the flat ribbon cable fron the SSB board to the convergence board to see if it is seated properly (may have been bumped while you were working on the set).

Also check for cold solder on the flyback.

Check the 3 small brown square pico fuses sitting in a row next to the flyback, one of them is for convergence (I believe it's the middle fuse)

----------------------------------

Here is the way to enter the service menu:

1. Press and release the POWER button to turn
the TV OFF.
2. Wait 10 seconds before trying to enter the Service Mode.
3. Using the front panel buttons (Not the remote) press and hold the VOLUME DOWN and CHANNEL DOWN buttons for at least 8 seconds.
4. The TV will switch on and come up with
the service main menu on the screen. LED
will illuminate before the picture comes up

Hope this helps -- Dan
