Error Code 30:

Sometimes an error code 30 will appear on a G70, but only when attempting to do 1080p. All other resolutions are OK. A 30 error code usually indicates a bad DC board (convergence), but replacement of the convergence board doesn’t get rid of the issue.

It seems that a memory location in the G70 can be corrupted and it needs to be deleted. This memory is located on the Ya/Yb boards, and can be deleted in the following manner:

1. If using a Moome HDMI card, cover the infrared receiver on the card.
2. Do not feed the projector a signal. Disconnect your Blu-ray player, PS3, Receiver, etc.
3. Using the remote, perform the following steps:
   a) Enter into Service Control Mode by pressing Enter, Enter, Up, Down, Enter on the remote.
   b) Enter into Special Service Control Mode by pressing Enter, Enter, Left, Right, Enter on the remote.
   c) Go into "Input Info".
   d) Delete the memory that the projector originally assigned to 1080p. If more than one exists, delete them all.
   e) Turn projector off.
4. Reconnect and turn on the Blu-ray player, PS3, or Receiver.
5. Turn on the projector and let it sync and create a new 1080p memory.
6. Redo all focus and convergence.
7. If using a Moome HDMI card, remove the cover from the infrared receiver.
