Kortek MS7-20L chassis, unknown tube, no picture, no neck glow... Please help

Hi I just got my first cab after years of using custom built sticks and a converter to hook my boards up to a TV...

My problem is that the monitor doesn't show any picture... I have been trying to learn from blog's/forums/youtube on how to identify my monitor/chassis and try repair this myself but so far I've had no luck...

Link to Flikr for pictures of the cab/monitor/chasis

Things I know / have tried...
Kortek Chassis.. (Model MS7-20L Nanao copy)
No picture...
No Orange glow on the neck, have tried re-positioning the board, seems like a tight fit
Fuses are OK...
Haven't tried a cap kit yet as I wanted to find the model number first and maybe a manual...
High pitch noise like any other tv/monitor I have heard... Think this is OK ???
Dirty board (i plan to clean today :))
No apparent bad traces on the chassis or neck boards...
Some components look a little burnt on the sides as there close to other components...
I'm assuming the flyback works as I have discharged this a few times and seems to be charging and discharging OK...

I plan to replace any bad components and get a cap kit/identify each cap and replace...
Does anyone have any other suggestions of what I can try before/after this...

Thanks in advance for your time and help..

Cheers

Fixed: :)

OK so a fun few days I've had,.. I've gone from a monitor with no image, no neck glow and didn't have a clue what was wrong or even the model number... to a fully working monitor...

After asking around here, got the model number,. which was slightly mis-identified i think as this is slightly different to the pictures of the MS7-20L model...

Asked thereal(legend)bobroberts and he didn't know this model (from the pictures i shown him) as i was hoping for a cap kit...

So i set out, to clean it up with isopropyl alcohol, re-solder a few bits, replace one cap after checking everything with a multimeter, a slight tweak of the vertical hold and to my suprise it kicked back to life and is looking great :)

Just want to thank the people here for the responses, great to see there is a community active and ready to help with this stuff...

I still don't know the exact true model number of this so if anyone can still identify it that would be great and maybe a help to future owners of this model,.. there must be some out there...
