Laptop screen inverter issue (Toshiba Satellite A205-S4587)

\015 Toshiba Satellite A205-S4587I believe this laptop is about 2-3 years old (it is not mine so I am not certain), and I believe the issue is with the LCD inverter. After about an hour or so of use the backlight will shut off. I've opened up the case to look at the inverter, and the plastic casing around it is warped and somewhat melted. The plastic piece that that inverter is mounted on is also warped and melted in places. On the back of the inverter itself, there are darkened burned spots.I'm not sure if the inverter is the problem or if there is an underlying overheating issue. Given that that the laptop is a few years old, the inverter could have gone bad. (I don't know much about electronic components, but could it be possible that the internal resistance of the inverter has increased, causing the inverter to generate more heat?) Another possibility is that the inverter is not properly cooled, but from what I've seen, underneath the screen is a universal placement for an inverter and should not be a problem.I do hope that the inverter is the only problem. Do Toshiba laptops have a history of issues like mine? And, should replacing the inverter work, would I run into the same problems 2-3 years down the road? If cooling is an issue, are there any methods for preventing the overheating of an inverter? Any help and suggestions are much appreciated.\015

Answers :

Inveter issues are a common fault on laptops both new and old. In many cases it is up to the individual to decide if the laptop is still going to fulfill thier needs for the next few years if it is repaired or sold to provide some funds towards a new laptop.
\015\012I have not seen any special cooling products for inverters. I have seen laptops used as desktops with the screens left running for weeks on end which is not the primary purpose of a laptop. conditions such as those could lead to heat build up and the issues you have seen.
\015\012If you are confident enough to do the repair yourself then you can keep your repair costs to a minimum and replace the inverter.
