I have a 9200 that just squeals from the chassis,no raster, no OSD, are there any known common trouble shooting charts or procedures for these?

Does anyone service them in the USA?
 
Chad used to work on D9200s and D9400s... not anymore. Apparently they have some complicated failure modes he can't deal with easily.

Happ will take em, but they charge a hideous premium and IME their workmanship is rather poor.
 
Open r854 to remove scan voltage..
Check to see if its burned too.
You may need a load to monitor the secondary voltages
from the powersupply..with a 75watt bulb.
The idea is to isolate the circuit's,rather then switching on everyone at once..
Its all about troubleshooting,from start to finish..theres a few things that could go wrong..
Like the vertical ic if going to test if holding down powersupply
then remove solder from the vertical ic,then test secondary voltages again..
