I just recapped my 13" g07 everything went well I had picture but still had trouble with horizontal roll . I shut it down friday and when I powered it up today I have vertical collapse any sugestions? I also reflowed the sync pins and double checked for any cold solder connections.

I was playing with he vertical center pins when I switch it to the left I get about a 2 inch band of picture from the center towards the bottom not stable though rolling horizontally like crazy when I move the pin back I just get the flickering line changing colors . monitor is a horizontal. any help ?????????
 
Check for cold solder joints on all the parts that are in the 400's....
 
Ok vertical height pot does nothing, checked all components in the 400 range, de-soldered and re-soldered all previously replaced caps . I need to get details on transistors and check them nothing in my manuals
 
ok horizontal out put transistor reads .000 regulator transistor reads .246 I'm assuming the horizontal is shot I need to get the info on the vertical output transistors or would the bad horizontal be the problem?
 
Dumb question but how do I test the vertical output transistors in circuit or out and what readings should I have I can't find any info on testing them
 
Put a meter on diode test. try every combination with the black lead on one leg and the red lead on another leg (for example, C-E, C-B, B-E, B-C) then reverse the leads and test again. You should get a number reading (between .400-.700 or 1.3-1.8) or an overload reading. if you get a short reading (zeros or beep), pull it from the chassis and check it again. if it's still shorted, replace it.

Wiggle all the big parts while watching the solder pad below to see if you need to touch it up....
 
Ok here is what I got on the vertical output transistors x401
Left leg Red center leg Black .270 center leg Black Right leg Red .0L center leg Red Right leg Black .633 left leg Red Right leg Black .539 Left leg Black Right leg Red .0L Left Leg Black Center leg Red .270
X402 Left leg Black Center leg Red 1.240 Left leg Black Right Leg Red .221 center leg red Right leg Black .0L Left leg Red Center leg Black .544 Left leg Red right leg Black .221 center leg Black right leg Red .0L hope thats eaier to figure out
 
Oh the joy another failed attempt at getting this beast running . I got a few parts today that I ordered before the vertical collapse occured, new pot kit couple of resistors for R314 and R317and the non polarized caps for C301 and C520. I thought just maybe but of course still vertical collapse . I'm going blind staring at this stupid horizontal line change colors. Well I've done every other damn thing I guess I will order the vertical output transistors and the horizontal bottle cap as well.
 
Ok I'm about to blow up this f....ing G07 I have been back over every connection recapped it new vertical transistors new hot checked every resistor for an open ... I'm at a total loss I've never seen a monitor go this bad just a thin line mocking me
 
Measure the vertical yoke. You should get about 50 ohms or so (at least the 19" does). I had one that had that problem and the problem was a bad yoke....
 
Ok well I got back to this again today . I re-soldered every suspect joint I checked the yoke,it tests perfect went over everything with a fine tooth comb and still just the same damn line running from side to side . Anybody out there want to take a crack at this thing any other ideas before I permanently shelve the thing.
