If some technical problem happens after OM it is not safe to trooble shoot when in LVP. Solution to problem may not be as clear as in your example and mistake would be costly. You should Go-arround first and troobleshoot later. A new briefing should be made and a/c prepared accordingly.
There may be exception that should be in company LVP policies and briefed before app, like "For any failure bellow OM, GA shall be performed except for A/T failure for cat II"
Some companies have single callout for any failure bellow OM in LVP like "Alarm" which calls for immediate GA
Hope this helps
