I recently replaced my DLP chip due to white dots. After replacing the chip my screen is now off center. I have double checked that everything is square upon reassembly. Recommendations to help align? I do know that I can adjust both vertical and horizontal but that does not address anything diagonally to help center the picture.
You need to align the optics mechanically. If you changed the dlp chip and its not centered then the chip is not shimmed properly or the reflection mirror behind the lens needs adjustment. You should get a service manual for that chassis and follow the directions. there may be an electronic method but I am not aware of one.

This sounds like one of the 9 volt regulators on the small signal board is going bad, supplying less than 8 volts. I have seen this is several of those sets. The IC needs to be replaced and if you do not have experience in servicing projection TV's then I suggest letting a qualified tech handle it for you.

the pico fuses will usually need replacement when the Ics go out they take out the two 5amp pico fuses.You can get replacement picos at the following link.

Good Day;
1. Red status LED, self-diagnosis error 44, check for open F9A06 on the Power PCB part # 283P128050 on the Power PCB 2. Red lamp LED, self diagnosis error 34. Check for 5-volts DC at J-9 connector pin 1 and 2 on the Engine Driver PCB if missing replace the Power PCB part # 930B921002 3. LED stops blinking after 70 seconds of plug in but will not power on. This model is equipped with a keyboard lock feature, this can be mistaken as a no power condition. To unlock the keyboard press and hold the "menu" button on the front panel for 10 seconds 4. LED stops blinking after 70 seconds of plug in but will not power on. Check for 3.2 volts DC at connector LE pin 3 and 4 on the Control PCB, if low suspect problems with the switches/buttons on the Control PCB part # 935D776001 5. LED stops blinking after 70 seconds of plug in but will not power on. Keyboard is not locked and key inputs at connector LE pin 3 and 4 check good. Suspect the E2P PCB part # 934C121001 6. (LED does not stop blinking after plug in) Disconnect the USB connector from the card reader to the front from the Chassis, if the LED stops blinking after 70 seconds replace the Card Reader part # 299P271010. 7. (LED does not stop blinking after plug in) Disconnecting the USB connector from the Card Reader did not help. Remove connector FC from the FMT PCB and plug the unit in, if the LED stops blinking after 70 seconds with FC removed suspect a problem on the FMT PCB (part # 930B924002), if the LED keeps blinking with connector FC removed suspect a problem on the DM PCB (part # 934C116002). 8. (LED does not stop blinking after plug in) On the DM PCB (part # 934C116002) check C81A2, C81A3, C81B3 and C81B4 (1000 UFD, 16V, 105C), if any are bad, replace all of them with part # 181P734030 (680 uFD, 16V, 105C). See Service Tip VS-78A 9. (LED does not stop blinking after plug in) On the FMT PCB (part # 930B924002) check C8F19, C8F21, C8F22, and C8F27 (16V 1000 UFD 105C), if any are bad, replace all of them with part # 181P734030 (680 uFD, 16V, 105C). Good Luck, big irish.

the DM and/or the FMT board are going bad. the chassis needs to be rebuilt. check out www.tv-techs.com

Thank you to "TheScreenGuy". He replied with an answer that says the vertical sync is automatic and that I need to replace the SSB. Thanks!!!
