Question about HP Televison & Video

1 Answer

HP Touchsmart 310-1033. My computer works, however; I can't see the screen too clearly. It flashes or blinks as if it's going out. I did a diagnostics and then took it to the shop to do their diagnostics and nothing. It's not a hardware issue. The repair shop wants to charge me $99 just to open up the computer to see. I'm looking for a less affordable option. A DIY option, if possible. Does anyone know what can be the issue? As I mentioned before, computer works, I just can't see the screen. It looks like how a TV looks with white snow or white noise or fuzzy.

The first thing to do is go into the device manager and delete the drivers for the display and let windows reinstall them. It may be a bad or out of date driver. So when you restart the computer it will put the driver back. Since you did not post the operating system, there is not a lot more I can tell you. If this does not help, you can try an external monitor to see if the problem is present there. If it is then it may be a display chipset issue.

    I'm sure it would be helpful but I can't see anything. I would have to rely on memory to know where the drivers are or to access anything like a folder or document.

SOURCE: tv picture looks grainy like it was shot on video

well most lcd and plasma tv's above 36" will look grainy on standard definition because they are made for high definition so if you do not receive a high definition signal to your tv then that would most likely be the problem

Hp TouchSmart 310 wont start,power light flashes

The LED light has now turned into a diagnostic light. The fault is a bad Power Supply.
Replacing it however, is easier said than done.

I don't know what exact model of the Touchsmart 310 series you have.
(Examples such as TouchSmart 310-1000Z, or 310-1125f, or 310-1155y, etc.)

The TouchSmart 310 series of All-In-One desktop computers, has a battery, and an AC adapter, (Charger), for power.

Test the battery with a multimeter set to DC Voltage.
{Symbol is a dotted line over a solid line. If there is more than one DC Voltage setting, set it to 0 - 50 Volts }

Should be close to 18.5 Volts (DC)

Battery is low?
Check the AC adapter (Charger)

The middle metal cylinder of the plug that goes into the computer, is Positive.
The outside metal shell which surrounds it, is Negative.
Again, 18.5 Volts (DC)

Check both then post back in a Comment.

By the sound of it you have a BIOS problem. This can happen with a bad flash of the bios HP automatically updates the system if you have not shut off that feature. You may have recieved a bad update. It may also be youre power supply. Check to see if your power supply has the full voltage if you have a Voltmeter. Try reflashing the Bios if you can and make sure to check the "clear nv ram" feature if available during the flash process.
Hope this helps... Dale

We have an HP laptop and is flashing three times when i try to turn on the laptop.. previously it had went completely black in themiddle of using it and now won't turn on at all what does this...

Hello, this problem can mean the processor is faulty. Normally when the processor gets faulty or destroyed the light blinks but doesn't come on at all. I suggest you take it to the tech department for diagnostics. Hope this solution is helpful. Have a wonderful day.

The lightning bolt on my hp touchsmart tx2 flashes

that means your laptop has no power so your battery is dead which would explain why it shut down on you, and that means its not charging so it would either be the adapter or the port on your laptop
