Greetings,
My DELL 2007WFPb stopped working properly from yesterday, which I bought almost 6 years ago. I googled and got here to find lots and lots of priceless information from others. Thank you for those who shared all the experiences.
Symptom)
- The screen shows without problem only for 1~2 seconds from being switched on, and goes to black right away.
- Shining flashlight to the screen reveals it is actually showing the produced image by PC, so the problem may be with the backlight.
- USB port has no problem
Brief diagnostic of inverter board)
- Disassembled it and checked all the capacitors, but they don't have visible leakage or something
- Checked three transformers: all three show almost the same resistance around 1.04KOhms. (Between pin#1 and #8, #4 and #5 accordingly)
I suspected one of these transformers would have gone, but they look like being OK. Attached photos of inverter board and PSU. Do you have any idea what I should do next? Thanks in advance.
