Siggi¡¯s right¡ get the proper manual¡.artek¡¯s are very good¡.
read the manual¡. Tek has been very very good about teaching you HOW it works and then letting you trouble shoot it. The 465b is a very good scope to work on. take the feet off of the back and the two center screws and then carefully slide the whole cover off. LOOK!¡.. study the manual and see where things are and where the dangers are and where to make your test measurements. most of the 465 has individual transistors making things a lot easier to test. from the look of your video 1/2 of the horizontal amp is not working. first just for fun¡wiggle any of the transistors on the horz bd that are in sockets¡. you could get lucky¡. then as Siggi suggested, check your power supply voltages. go slow and read as you go..you¡¯ll get done¡there is plenty of help here¡

One more thing. It appears Artek Manuals have three different 465 scans for different serial ranges < <>>. You may want to buy the one that matches your scope's serial number (on the front of the scope, I believe). Dave's scans are going to be better quality than the free one on bama, and OCR-ed too.
Feel free to shoot questions and observations as you go, someone may notice trouble you miss in the heat of the moment. In addition to tinkerers like me, there are real-life experts hanging out here, but they seem to reserve themselves for the tougher problems :).
Have fun,
