Question about Dell E173FP 17" LCD Monitor
Hi replaced the transistors x4 now the screen comes on for 3 seconds and goes offf again and if iturn the switch off and on again it does the same can anyone help thanks
You must re-solder all the transformer joints (four of them next to the transistors) for a fix. There are cold joints on the transformers that break, causing the transistors to fail. Reheat the joints and add just a TOUCH of solder to them on each and every lead. Don't use too much solder, or you'll cross connect the leads.
That'll fix it.

When you replaced the transistors(All 4 C507) I hope you also resoldered the inverter transformers and the FET which drives the transistors.

I think one of your back lights has gone, there are two of them, I imagine that when it does come on, it's rather dim.
If so, the monitor is scrap.
