Looking for the values of R and SG located near the flyback.
ZD is an 18 Volt zener. When powered up again the fuse and trany went. Princeton eo70 monitor with R and R burned, I cannot identify their value.

If the flyback tests fine, check the G1 and G2 voltages. Removed Hor Def yoke. I am unsure as to the nominal specification of this hopefully bipolar transistor because the number printed on its case C 4B4 does not come up in any searches I have done. NEC multisync 70 monitor will intermittently not turn on from cold start.
Try checking the vertical IC, R, and R I have a couple of G monitors but do not know what FBT to get. This may prevent having to go into it again later. Jumper any cracked PC runs. I need help trying to locate it TLF flyback. Push power off on the TV.
I need cross reference for a transistor BSS89 for an Acer e monitor. The monitor came on for a few seconds, then the flyback began to squeal and blew Q again. Check carefully for cracks, with magnification, and jumper any broken PC traces.
Compaq v70 monitor, the video will expand and contract horizontally. Do people’s faces look natural? That other diode is a 12 volt zener, with its anode connecting to R I replaced that and it worked well for a couple of days.
Viewsonic 17GA monitor when it powers up, or changes scan rates, it takes sometimes over a minute for the screen to reach full brightness.
Desolder pins 1 and 5 on the flyback, and check for a high-resistance leakage between these pins. If no zener is installed at location ZD, in parallel with R, and if problems still persist, you might consider installing an 18 to 20 Volt zener at location ZD as protection for the gate of Q I agree that swapping yokes will be a convergence nightmare.
Check that VREF stays at about 2. Often, however, that Zilog, if thermal, can be made to function by attaching a grounded heatsink to it. Service menu TV Sharp.

All other aspects, ie focus, work with no problems. If this chassis was handled roughly, there may be cracks on the G board near the flyback, often at the mounting screws, which should be repaired.
Pay attention to what you are doing and don’t miss anything. Power stays on after removal of Q10 DA.

Polycat monitor of a pick and place, the input automatically switches between the built in computer and ccd camera connected to the loading arm of the machine. Acerview 76e monitor e powers up with black screen and LED is on green. I know that one of the diodes is a 1N but the other one disappeared.
Related Questions P and P Checked all the diodes, caps. The Princetons also can get bad solder on W also on the FBT, but probably not an issue anymoreand bad yoke connector connections.
Also, look carefully for any bad solder in the power supply and horizontal section. IBM monitor has burned resistor Rcausing it to appear dead when a video signal is applied. Checked that the power supply works, but apparently in a standby mode. Could it be the monitor cable?
The screen cracked a few times, then went dead.
