This is a Star Trek GNDN USB mini port for the Haier factory to update the firmware (software stored permanently) in the TV.
If you return the set to Haier for servicing under the 90 days labor, 1 year parts warranty, Haier will probably just send you a refurbished unit.
Part of the refurbishment is for the Haier factory to update the software which runs this digital TV.
If you connect your computer to the port with the correct cable, nothing will happen.
No drivers or user mods (hacks) appear to be available.

How long will the battery last? Can it be recharged in my car? How long does it take to recharge?

Haier HLT71 portable TV battery is good for about 2 hours.
You can recharge it from your car cigarette lighter jack.
Or from your household 120 VAC wall plug.
It comes with both adaptors you need.
It takes about 8 hours for a full charge.
You can charge the TV while watching it, or you can power it off.
Not sure if it charges faster or the same if you are watching.
If the battery does not give you 2 hours after the first charge, try charging and using it a few more times to bring the battery up to full capacity.
Replacement batteries are available on eBay. Good to have for backup in case of a storm.

I have coloured vertical lines on my 40-inch Samsung Series 7 LCD tv, sound ok, what is wrong? Can it be fixed, Yasna

is the screen full of vertical lines? It sounds like your Tcon has gone faulty but...there is hope. Firstly, only if you are competent with electrics follow the procedure bleow, else get a qualified tv engineer to inspect your tv.
Remove the back cover on the tv.Looking in from behind, check the power supply which is the board connected to the mains power lead. Check the capacitors, making sure none of them have bulging tops.These are the components shown below.
The caps shown below are an example of faulty caps, with their tops bulging.
This model of tv is prone to this condition, and if you have any bulging topped caps, replace them.
Next check the Tcon LVDS lead connection. The Tcon is the board located top centre of the screen and is enclosed in a metal plate.It has a lead connected to it that goes to the main board. Clean the connector at the Tcon.Be very careful though because the connection is fragile. It can be removed by gently squeezing in either end of the connector and gently pulling outwards.If these procedures are not successful, replace the Tcon.

Haier 37" LCD TV...need a power supply

Find a differant web site because this one is run by a bunch of money grubbing technicians that really don't have a good solution but would love to charge you to take a look at it.
After you pay to have your tv shipped to them only to hear them say that it will be $700 to fix it or you can pay to have it shipped back still in its junk state most people probly say keep it and they then fix it for $25 and sell it to another ******!
