My lg view is stuck on a blue screen with a code showing....error fatal file dog ui. what do i do can it be fixed?

that is called the "LG blue screen of death"

you will have to restore it to factory settings.

follow the steps below:

1. Download the LG Vu firmware files from this site ( Unzip it. These files contain the entire LGAPP firmware folder. Then unzip it. It should create a LGAPP directory with every file that was on your phone when you got it. I know DH said to not replace the entire LGAPP folder because it may brick your phone but, hey, it's already bricked so not a problem.
2. Get into EFS and connect with your phone. Get to the gang screen on your phone using the steps if you have to.
3. Rename the LGAPP folder to something else (LGAPP_bad). Do not delete it. There are some files that are read only and you get an error message replacing them when you copy the new GAPP on top of an existing LGAPP directory. This doesn't happen if you rename the old LGAPP to LGAPP_bad before you do the copy.
4. Copy the LGAPP directory you unzipped above to the phone and restart it.

LG KF390q Blue screen within the following message when turning it on: Error Fatal file: dog: UI line: 0 How do I solve this problem?

This is a system failure, the program could be corrupted. To solve this, bring the phone to an authorized LG repair station and have the firmware re-flash to the phone.

Aside from the firmware, there could be some components that needs to be replaced. Hopefully, firmware could fix the problem so that it would not costs you too much.

Have a great day!
