Got new STK392-040 chips and picture is still distorted. Manual convergence still won't alligne all colors.


the 183 is entry into the tech menu===you need to test all the low value resistors around the convergence chips(only 6 or 8) and they will read low and a resistor with NO reading may be your problem.

Also these sets use a pico fuse going to each chip--either right with it or back at the source----know what a pico fuse looks like"

I have a 52" rca hdtv. the screen looks like its in 3d. can this be fixed? model# hd52w67


It seem like a convergence trouble. I tink it is a ITC222 chassis in this set. If it is, you probleme is eeprom for convergence need to be reprogrammed and cause no power on convergence board.

Convergence is off, can't seem to fix.

No Picture after it's been on a while. Audio OK.


ok you have a vert sweep problem and yes its probably connected to in a way to the "tap and fix" problem! Seems to be n intermittant connection on the vertical out put Ic or maybe even on the rgb convergence ic?? The total loss of sweep though tells me that theres two differant problems! Maybe and intemittant connection on the vert output Ic as well as bad connections on the convergence ic??.
