I got the schematics for my monitor (dell d1626ht) and it came with a text file that said a common problem is failure of fa4111, and check to see if the IC is bad with cold spray. but i have no idea what exactly to do,(although i assume spray it down. Does anyone know what i should be looking for??
Thanx

This method of fault finding is used where you would have a normal picture at power up i.e. cold.

When the unit warms up the fault appears and using frezer spray to cool down the suspected component/s to see if the fault clears.
