Most likely cause:
Backplane lamps, and or the backplane power supply is defective.

I don't know the particular model, but in most of these models, these parts are replacable. I suggest giving out the set to a tech who is experieced at doing this type of work. The parts would have to be ordered from the manufacture.

SOURCE: My LCD tv's menu screen keeps popping up and won't stop.

Since it is brand new then should be OK.
Please return it to store and get another TV.

If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.

On Rear Projection : check lamp, lamp ballast, power board, and convergence.

On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.

SOURCE: lg lcd tv keeps changing chanels

Come on, lets try to solve this. Take the batteries out of the remote so it can't interfere and try changing the channels and volume with the buttons on the tv. If this works then someone has spillled something onto the remote and gummed it all out. You simply need to take the remote apart and clean it out. If the buttons on the tv do th same as the remote did then yes, take it back.

The menu keeps flashing on and off. I have turn the tv off 4 or 5 times but it still keeps flashing the light on the bottom of tv goes blue then red really fast


How old is your TV? This normally indicates a power problem. It could be any of the following: power supply on the TV, faulty power strip, faulty wall outlet, faulty circuit board inside the TV, faulty power cord/plug, bad airflow/clogged vents restricting air movement into the TV (can cause intermittent power faults),bad sensor inside TV. This is not completely inclusive by any means. It does mean that you should have it looked at. Someone knowledgeable/skilled should be able to determine the cause fairly quickly using a multimeter.

Several possibilities but most common seems to be power supply defect or poor connection. Check these resources. Note that other Youtubes that may address the problem are also accessible from the youtube link.

Update firmware lcd tv toshiba 32pb10e


How to Update Toshiba TV Firmware
  1. Plug a USB flash drive in to an available USB port on your computer and copy any files from the drive that you want to keep into a separate folder on your computer.
  2. Format the drive as a FAT32 file system. This erases all of the files currently on the USB flash drive.
  3. Click here to open the Toshiba Support home page.
  4. Click "Product Support" in the menu along the top of the home page. The Product Support drop-down menu opens.
  5. Select "Televisions" beneath Choose Category.
  6. Select your type of Toshiba TV beneath Choose Family. For example, options include 3D TV, LCD TV and LED TV.
  7. Select your Toshiba TV model beneath Choose Model.
  8. Click the red "Go" button to the right of the Choose Model section after selecting your Toshiba TV model. The product support page for that specific TV model will be displayed.
  9. Select the "Downloads" tab. If there are no downloads available for your TV model, either your won't be able to click the tab or there will be a message within the tab that says there are no downloads at this time. If this is the case, no firmware updates are available for your Toshiba TV. Check back periodically, as firmware updates are released as needed and aren't scheduled.
  10. If there is content in the Downloads section, look in the Category section for an item titled TV Firmware. If this option doesn't appear, no firmware update is available. However, if this option does appear, click the clickable link associated with the firmware. The TV Firmware Update and Release Notes dialog box appears. In this dialog box you can see the size of the firmware update file, when it was released, exactly what it addresses and more.
  11. Click the red "Download Now" button and save the file to your connected USB flash drive.
  12. Extract the contents of the ZIP file on the USB flash drive.
  13. Disconnect the USB flash drive from the computer after the firmware update file saves successfully to the device.
  14. Power on the Toshiba TV and then connect the USB flash drive to the USB port on the Toshiba TV.
  15. Wait a few moments for the "Firmware file is detected in USB" dialog box to appear on the screen. Select "Yes" to update the firmware. A progress bar displays on the screen. Be careful not to turn your TV off while the firmware is updating. The progress bar changes to a "Success!" message after the update successfully installs.
  16. Disconnect the USB flash drive from the TV and then restart the TV. After the TV restarts you can resume using the TV as you normally would.

Hi. i have a LG lcd 37" flat screen t.v. In the


Hi Andy,

Unfortunately, your TV does not have any hard-disk recording facilities built in. The reason for the "Record" option in the menu is that some other LG TVs share common hardware and software with your TV. This means they all have the same menu options but on some TVs certain options have no function or are disabled, e.g. the "Record" option on your TV.

If you want to record TV programmes, you will need to buy an external device with hard-disk recording facilities.

Hope this helps.

Regards,
BElectric
