I have a 27 inch WG D9410 digital monitor no screen pic. Monitor powers with green LED lit on Chassis board. Fuse is not blown and checks good.There is neck glow seen. Turning the flyback did nothing. Where to start. Tried dvi output and normal monitor output. Also there is no static on screen. Leaving monitor on for 5 minutes and fuse still didn't blow.
 
Ok pulled the chassis tonight. started testing the transistors and horizontal output transistor.didn't have much time tonight but I've checked about 5 so far and Q216 is leaking(faulty) and Q207 is bad completely double checked both just to make sure. One question do you pull the diodes out of circuit to test or test them in circuit? I have an ESR meter so caps I can test in circuit no problem. I'll post a photo tommorrow of the flyback and see what your opinion is.

Edited: I didn't realize it was copyrighted. Don't want to burn any bridges...thank you Ken.

If anyone is interested I can make a pdf file of how to operate it if you need it just pm me.

Q901 is the HOT..C5387
Do you have voltage on both sides of R901 .33 ohm 2 watt resistor
 
Parts List?

How you doing with this repair?
Did you do a cap kit along with Q207

I found when Q207 the Horizontal Scan Output Transistor
fails its because Cap 226 is bad.
The trans may have ran hot untill it shorted.
Poor or low Horz-drive will over heat a HOT!
