If you like this type of video, let me know in the comments. Stay tuned for Part 2 as soon as I receive my transformer. Thanks for watching! As always, keep doing everyday things!
I have 4 of them, and sure enough they've all lost their transformers over the years. My oldest one is nearly 20 years and old and still klcking, I've got another one down currently for another transformer replacement! 😁
i have two of these monitors, and i can tell you it now seems like it may be typical for those bottom two capacitors to bulge up. also hot spots seem to be prevalent on these boards, which now makes me think that the design flaw, is that the monitor should probably have a fan included in its design, probably aimed at the transformer. Inverter Transformer SPI 8TC00332 is the component name for it.
It's interesting that, if I recall correctly, it was those same two capacitors which seemed to have gone on my board as well. I was going to ask whether that might be indicative of some sort of design flaw, but given how long my monitor lasted, I don't think that's necessarily a fair question to ask. Looking forward to part two, either way!
Thanks for the comment. Oddly enough, those 2 bulging caps are filters for power for the digital board that plugs into the power board. The problem to begin with was that the digital was coming through fine, however, the backlight wasn't lighting (or lighting for 2 seconds). So, even with the bulging caps, the digital board was still working. The backlight problem was twofold: 1. All of the other caps had hotspots around them, therefore they were probably dried up and less effective or bad. They were all replaced. If replacing caps on a power board, always replace them all, even if they are not bulging. This could be why the transformer got hot and burned out. 2. The secondary of one of the transformers that powers the lights was open and this type of lighting needs a balanced power supply so only half of the lights were lighting only briefly, due to the imbalance, and then would shut off.
My monitor is same model and working... It just takes a long time to come on. Blinking blue light by power button soon as I hit the power button. After about 10-15 min it finally comes on (or if PC is not on, light turns yellow meaning it's ready) Haven't opened it up yet... but I'm guessing it's a bad cap somewhere... did yours do this?
Hi, thanks for the comment. No, my monitor would turn on for a couple of seconds and turn completely dark and only flash on again if cable disconnected. I did find half of the inverter transformer bad and that explains the partial turning on. I have not had time to finish the video, but should get back to it soon. From your description, sounds like a power supply/capacitor problem for your monitor.
I have a different monitor with a similar FSP power supply, and after 12 years ALL the caps on the secondary went bad, even the ones that weren't domed, from gaining enough leakage to drain it in seconds and at least a 40% capacity loss, to complete capacitance loss. The slow decay of the capacitors just past the diodes has caused the capacitors further down the line to dome and pop. The section of the power supply gets quite hot from the diodes, and capacitors appear to get slowly cooked. I think i fixed the power supply but possibly ruined something else by now after assembling and disassembling it a bit too many times, it whitescreens now, meaning the panel isn't doing anything, but the processor board appears to be running. EDIT: I. Am. A. Stupid. Little. Kitten. The panel connector partially slid out - tape gave up. Phew, it's running now! Happy that no latch-up damage occured!

Siana Gearz Thanks for the comment. Ha, we all do things like that, glad it was that easy.
