Hi
I have a Compaq F750us and its display doesn't turn on. The video card is fine because I can connect to an external monitor and everything runs just fine. I've been having this problem for sometime now. Earlier, the display used to turn on occasionally and everything went well after it turned on. I'm sure it isn't a coincidence, but the display was more likely to turn on after folding the laptop display to various degrees. Only recently it has stopped to turn on completely even after a lot of folding and unfolding. It simply won't turn on now (except once in probably a 100 times of switching on).
My warranty has expired. I've checked other forums and the problem seems to be one of the following:
a) LCD cable could be faulty
b) inverter could be defective
c) there could be a loose connection somewhere
d) there's a problem with the display itself
The last option is least likely because only yesterday the display again turned on and everything ran smoothly.
I went to the HP service center in Hyderabad (Redington India, Raj Bhavan Road, Somajiguda) and they zeroed down to the same four options listed above. But they want to keep the laptop with them for a day or two to diagnose it. They didn't exactly look like people I could trust (especially after I'm out of warranty). So, I've decided to look for help online.
Can anybody give me any tips on how to repair the thing or at least figure out exactly which part of the laptop is defective? Also, if there's someone in Hyderabad (someone reliable) I could contact personally I'd be happy to do so.
