那应该是背光启动电路,很有可能是楼上讲的哪个电容爆了。

那不过一两百块的新的低档货就不要拿出来丢人现眼了彭长老 写了: 2025年 8月 12日 16:01 24英寸的显示器,新的也不过一两百块钱。80刀是修好了,可毕竟是太老了。 就比女演员,再换零件装嫩,但毕竟70多岁了,随时见棺材。多花点钱,弄个花花闺女不好吗?

赞一下楼主的动手能力。但如果纯粹从经济角度来说,同城二手买一个也许更实惠。
前不久淘了个 Dell 2723Q (4K屏),才 $20,成色很好。当然,同城二手的缺点是时效性。如果急着用,也许不能马上找到合适的型号或者价格。如果不急,一个月内基本能找到成色和价格比 eBay 好的。现在很少用 eBay 了。买新东西基本上是 Amazon 和 Walmart,淘旧货就 Facebook Market Place。

你那闪瞎眼睛的低频pwm+wled背光的才是妥妥的垃圾彭长老 写了: 2025年 8月 12日 17:49 现在显示器这是垃圾价格。 32英尺的FIRE TV, $99, 加上折扣$75到手。 10多年的显示器,一切正常,估计FREE才有人要。有点毛病的,估计FREE都没人要。

自己整配件,修个垃圾显示器,瞎折腾费时间费钱。说实在话,就你那显示器那丑陋的宽边, 即使是好的,我都不想用。
我几年前折腾电视机, 那我是赚钱的。 一个彩电,保修期间,好像是不能打开了, 师傅上门检查报个价格,记得300多刀。 我记得AMAZON上, $12.34刀, 买了个二手的供电板, 换上,修好了。 保修给了300刀,我只花了$12.34, 这才值得折腾。
瞎折腾要学会算经济账, 当然如果说那是你的兴趣就另当别论了。

楼主这么迷信 CCFL。 我问了一下AI:
Do any new monitor models still use CCFL?
No new monitor models use CCFL (cold cathode fluorescent lamp) backlighting as of 2025. All recently announced and upcoming monitors from major brands employ LED, mini LED, or OLED backlight technologies, and the monitor market has fully transitioned away from CCFL several years ago. The comprehensive lists of new and forthcoming monitors show only LED-based solutions, even in niche categories like professional or gaming displays.
CCFL technology is now only found in much older, used monitors. Enthusiast discussions and recent user experiences confirm that CCFL-backlit monitors are now exclusively available secondhand, and are generally considered obsolete for mainstream or professional use. Even in manufacturing and industrial contexts, CCFL is being phased out in favor of LED because of efficiency and reliability advantages.
If you seek CCFL for specific visual characteristics, your only current option is to find a refurbished or used model—no modern monitors are produced using this technology.
