Question about Dynex Televison & Video

1 Answer

After about 30 to 45 minutes of operation the screen will start to flash with a white background and colored lines from top to bottom. The flash is only fractions of a second but from that point on gets more frequent. When turned off and allowed to cool the problem will go away until 30 to 45 minutes of operation again.

Hi,

I am afraid I have very bad news for you.
The issue you describe is consistent with a defective LCD panel.
This is a common occurrence with these LCD tvs.
The problem is located inside the LCD panel,one of the ribbon cables that connects the glass panel to the driving boards is making poor connection.
These cables are bonded into the manufacturing process to the glass panel and the boards,and they are nor repairable in a regular service shop(manufacturing facility only!)
The lcd panel can be replaced,no doubt about that,but the cost of the panel will be very high,making the repair uneconomical,exceeding the cost of a new unit.
Besides this,the Dynex brand is a Best Buy private label ,and the whole parts supply chain is controlled by Best Buy,making hard to find replacement parts for it.
What you can do -take the tv set to any Best Buy store,they will send it to the nearest service center,and then a tech will call you with a repair estimate.
You still can deny the repair anytime,in this case you will be liable only for some shipping and handling charges.
I am really sorry for this bad news,like I said this is a common failure on all LCD tvs,this is why I recommend always to buy an extended warranty if you can afford,since these new tve sets are all cool and fancy ,until they break,usually soon after the manufacturer warranty runs out.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Riding Mower No Start Troubleshooting


  • First check the air filter to see if it getting air and gas.
  • Check your gas cap. If your gas cap is clogged, your fuel tank can get a vapor lock, and you will have no gas flow. Loosen the gas cap to see if it will run longer.
  • Check the gas filter (if you have one on the mower) to be sure it is clean and has good gas flow.
  • Check to see if you are getting spark at the plug. Check out the video below.


If the engine clicks but will not start, the battery or solenoid is often to blame. To find the battery on a riding lawn mower:

  • The battery may be under the hood
  • The battery may be located under the seat
  • You may need to lift the hood to find the solenoid
  • Check the owner's manual for the battery or solenoid location

Check to see that all wires are securely connected and that the terminals are clean.


If the lawn mower still does not start, the problem may be with the fuel, if it was left in the mower over the winter months the fuel may have become stale or watered.. If the fuel appears dirty or contains water, you will need to drain the fuel tank and replace with fresh gasoline.

Other reasons for the mower not to starting also include:

  • Damaged or loose wiring
  • Problems in the carburetor
  • Maladjusted or damaged engine valves
  • A blown fuse
  • Ignition switch may be faulty

How to reset nokia mobiles life timer to ''0''


Nokia life timer is a counter that keeps track of the Total call time of your phone. It will show how much the phone has been used, and it?s the best thing to check if you?re planning to buy a used Nokia Mobile.
To see the Total Call Time or the life timer counter, On the standby screen type the following code *#92702689# (Easy way to remember this is ? *#war0anty#). And it will pop up a message that shows the life timer in hours and minutes.

Here is a detailed procedure to make this life timer zero.


REQUIREMENTS:
The following files are required to reset the life timer:
  1. Nemesis service suite link: Download from Here
  2. lifetimer.pm file: Download Here
PROCEDURE:
1. Download and Extract the lifetimer.pm file, and Download Nemesis Service Suite.

2. Install Nemesis Service Suite on your Computer, It won?t take much time.(select the first option)

3. Install Nokia Cable Drivers (No need to install, if you have Nokia PC Suite already installed)

4. Connect The Phone in ?PC Suite? Mode to the PC

5. Open Nemesis Service Software

6. Click on ?Scan for new Device? Button on Top right Corner 



7. It Will take a few seconds to scan, and it will load up the software interface after communicating with the Phone.

8. Click the ?Phone Info? Button.


9. On the Bottom, Select and open the ?Permanent Memory? Tab, which is next to the Fbus info.


10. Click the ?Write? button on Below right, and open the Extracted lifetimer.pm file on your PC. 


11. After the lifetimer.pm file is opened , it will immediately start writing it to the Phone?s EEPROM Area.




12. The Procedure will end when the progress bar reaches 20%. This is normal , and on the bottom right side, it will display its done.

13. Unplug the Phone, and Restart it.

14. After boot up, Check the life timer .


Note: This method has been tested on following devices: Nokia 6630, 6670, 6680, 5500 sport, 5700XM, 6110 Navigator, 6120 Classic, N70, N72, N73,N76, E50, E51, E61i, E65, N80, N91, N95, N95 8GB, 5800XM Mobile devices. If you want to try it on other S60v3 or S60v5 mobiles, do it at your own risk.


Caution:
  • Power Failure During Writing will cause damage to the Phone, And there is a chance that it might brick the phone as well.
  • Loose, worn out Data Cables Might fail the Writing process, and there are chances of damage to the EEPROM area of the phone.
  • Do not attempt this with phones that are not included in the confirmed list.

Blue Vertical Line


It is sounding like when the laptop is turned on and heats up a bit, the line appears? Sounds like one of the panels is going bad or atleast has developed a problem. below are some tricks you can try to lessen the annoyance of the line. Dual-Scan STN displays are composed of 2 panels behind a single protective panel or screen. Because you are looking through the protective screen the display appears to be one large panel even though it is not. There is a physical separation line (gap) at the point where the two panels meet. When the computer is on and being viewed it is not unusual to see the visible separation line with the Dual-Scan STN displays. The line, actually the fine gap between the display panels, appears because the color and light pixels cannot run along the very outside edges of the panels. This line (gap) between the panels can be seen as a fine gray line and is most noticeable when viewing on a screen with a white or light background. Note the line may not be as noticeable when the screen is displaying certain colors or darker backgrounds. SUGGESTIONS: It is not possible to completely eliminate the line but there are some things you can try to reduce it's visibility. 1) Lower the display brightness/contrast. The brighter the backlight the more noticeable the line. 2) Use Wallpapers and Screen savers that use darker colors. 3) In the Control Panel/Display applet under appearance try different combinations of color schemes for your Window and Background choice Let me know what happens. Good Luck, Tim
