Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

SOURCE: after lightening zap

Call your insurance agency as this should be covered under your homeowners policy. The main driver board is made by JeanCo of Taiwan and is not replaceable and cannot be ordered as a part.

Good luck

SOURCE: SAMSUNG LE32R73BDX/XEU TV

just spoke to Samsung support and it turns out that the freeview tuner had froze and needed resetting. To do this put TV on standby and then push in series these buttons on the remote: 'info, menu, mute, power' the TV will then turn itself on and display a menu. Press the 'down arrow' untill you've highlighted option 12 - 'reset' and then press the 'right arrow' to enter the option. TV will turn off and when you turn back on it will start in 'plug & play' mode as if new. Set the time and country options and then it will perform a complete scan. I've just retuned mine and all back to normal. Hoorah!!!! :-)

SOURCE: cant change the input mode on my LG 50pq60d. its in antenna mode and will not change to av

I think this calls for a phone call to LG customer service to see what can be done and to inquire if this is known issue in this model--all these companies keep extensive records or model versus problems.

Nothing you are likely to deal with in something other than a repair shop---most of The LCD type sets this size never get fixed from a cost point of view it usually is cheaper to buy a new set.

Inverters that drive the screen and or back lights if used are the common issues but there are others.

SOURCE: my coby tftv3227 tv won't turn on and has no sound plugged it in new power source and still nothing what to do?

I see so many here with no sound/nopicture issues:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.5_27_2012_5_44_12_pm.jpg5_27_2012_5_44_31_pm.jpg

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

How to get Sanyo dp50741 out of hotel mode?!


This is for Panasonic but might help you
Getting out of the hotel mode is very easy. Just go get the Panasonic remote and open your tv. Go near the tv and hold down the AV/- button on the television itself. Then use the remote and press the AV button for 3 times. A hidden menu on the television screen will appear. Turn off the "Hotel Mode" from the menu and exit. Do not touch anything from the hidden menu except the hotel mode. Now you can use your tv in normal mode. The remote is required to access the hidden menu so be sure your remote is working and has working or full charged battery before doing the steps above.

My DVD 958 not showing with the hdmi cable through the television


You first should hook the device up with AV cables, after you uses AV cables , you will get a picture, once you get a picture, you need to go into the setup menu and turn on HDMI, once you do this, then you can switch to the HDMI cable.

Coby kyros mid 7022 is stuck on lock scteen, how do I get around this? Also goes into hibernate for seemingly no reason. Very new android user, no clue what I'm doing


Here is the instruction on how to do the factory data reset when a customer locks the system and lost his security password/pattern. This instruction works for MID7016 and MID7022. An end user must follow each step precisely. Otherwise, he/she will not access to the system menu mode.

  • Connect the AC power adapter.
  • Turn on the system.
  • Press and hold the power button until the popup window of "Device options" appears on the screen.
  • Select the "Power off" option from the popup window. You will see another popup window of "Power off".
  • Select the "OK" option. The unit will turn off.
  • While holding down the "BACK" button, press and hold the "POWER" button until Coby logo appears on the screen.
  • Release both buttons once you see Coby logo on the screen and wait for a while. The Coby logo screen will change to Android logo.
  • Wait about 15 seconds after you see Android logo. (Do not press any button while waiting. If you do, you will not be able to access to the system menu.)
  • Press the "BACK" button once. The system menu screen will appear on the screen.
  • Choose the "wipe data/factory reset" by using the "HOME" and "MENU" buttons. (The "MENU" button will allow you to browse down through the option list, while the "HOME" button will allow you to browse up through the list.)
  • Press the "BACK" button once you select the "wipe data/factory reset" option. The confirmation message will appear on the screen with YES or NO option.
  • Choose the "Yes - delete all user data" option by using the "HOME" and "MENU" buttons.
  • Press the "BACK" button once the "Yes - delete all user data" option is selected. It will perform the factory data reset. Wait until it is done. Once it is done, the main system menu will appear on the screen again, and the "reboot system now" option will be selected as a default. If not, you will need to select the "reboot system now" option from the list.
  • Press the "BACK" button to reboot the system. The system will reboot with the initial factory data setting. All user data will be lost.

Give the reboot at least 5 minutes. Do not assume the unit has frozen
