I have an Hitachi 51swx20b. Just replaced convergence IC's and resistors. Now the TV shuts off after a couple of seconds.

The service manual (page 61) suggests checking pin 4 of IP02 for 14V to 20V since the green LEDs are solid. The red LED is also solid and not blinking.

I can not find IP02 in the schematic, block diagrams or the parts list in the back of the manual.

Thank you for any help

I bet you have a solder splash shorting two of the pins on those chips you replaced. Take a close look at it.
