This fault can be caused by low secondary supply voltages often caused by the value of capacitors becoming low and requiring replacements but you will have to have a technician.

How to recalibrate scream. Image too wide I loses part of the image of each side of the screen (right and left)


before you think about recalibration or any electrical adjustments . lets review one is the whole picture over scanning the screen did you switch it into a different format like wide screen check that you may want to get the owners Manuel out for the help there. option two . you cleaned the optics now the picture is to wide ? did you loosen the lenses on top of the tubes ? there are wing nuts that set the static focus on the three picture tubes did you move them or loosen the look at which color is over scanning if its all of them then id suspect a format change using the factory remote its simple to switch it back the mouse pad on the remote is the 4 arrows with the center push button by left or right it will walk through those modes . let me know how that works out please .

Akai TV CT 2579A will not turn on. It is in standby mode, and pressing "on" with the remote causes a click noise but unit stays in standby mode ... the manual on/off switch does the same thing...


Suspect the problem is in the control circuit of the TV. Often the detector will go bad and have to be replaced. The only way to know for sure what is causing the problem, which parts that are no longer within factory specs and for proper repair all the electronics must be diagnosed by someone with the correct electronic test equipment and the skills to use the test equipment.

Hope that helps........

I have a Sony KP-53S35 53 inch Rear Projection TV connected to a Directv Receiver. The TV does turn on, but the screen goes blank and VIDEO 1 is displayed. It will stay on, but will continue to do this. ...


Hi,
Press any channel button on tv remote to switch its input source as TV to watch tv channels.
As you said, screen shows Video-1 display that means tv is set on input-1 that need to be changed, press channel button on remote or tv front to shift it on tv channels mode.
Let me know if you have additional question.
Thanks.

Can't turn on


When you turn the MAIN off you are killing all power to the set---Some advice---If you Google the model number of this set with the word problem after it you should find what I have seen a lot in these sets: they develop bad solder connections on the power supply printed circuit board---usually the board is about 18 inches tall and 12 inches wide--A number of sites online offer to have you ship them the board and they will resolder it for you.
I have repaired about 12 of these with this problem in the last 2 years---The board has to be removed(there are quite a few plugs that need to be labeled and removed and lots of screws that secure the board in place.)

Maybe not a job for a do it yourself person but the soldering (if it is your problem) will take about 45 minutes(including removal and installing board back).

Like most modern sets this set uses lead free solder and it is soldered(the boards) in a wave or one step process---over time from heat and expansion some connections may crack or even break loose----I would look at the POWER SUPPLY board(follow the power cord as it goes right to it)

If you have any questions or need help please contact me here.

Power/Standby light blinks green then screen goes blank (off) for


I have a similar problem. Just found out a possible solution yesterday. I am waiting for my lamp but here's what you need to do if you have replaced your lamp. Go into self diagnostics mode: Switch of your TV via remote, you will see red standy by light. Now,on the remote press "Display"=>"Channel 5"=>"Volume Up"=>"Power Button". All these keys need to be pressed within 3 seconds. You will now enter the diagnostics mode. Press "Jump" on remote (bottom right) 3 times and then press "Channel 2" 9 times. The screen will display your current lamp hours used.

In order to reset your tv to factory settings and for the new bulb to work you must reset this timer or else your TV will assume you are still using the old bulb and will automatically kick in "over protection mode". So here's what you do once you do on the lamp hours display screen. Press the "Channel 3" button on the remote 3 times then "Mute" then "Press Enter" to reset the timer to zero. Your TV should now work as normal. And remember, whenever a part is replaced all factory settings must be reset to zero. To do this, follow "Display"=>"Channel 5"=>"Volume Up"=> "Power Up" to enter service mode. Finally, press "Channel 8" and then "Enter" to put the TV back to factory settings.

The above mentioned is usually performed by a service technician and they charge somewhere around $95 diagnostic fee. You just saved this charge. If you see flashing red lights count them when they flash in sequence. This is a code for the techs to tell them what is wrong. These flashing red lights sequentially flash from 0 to 10 times to identify a problem. Usually, when the bbulb goes bad the only thing that might need to be replaced would be a "lamp Driver" aka "Power Block Assembly" $116.25 online from Sony, or the ballast. Sometimes, if you do not have a video a Thermal FUse can go bad which only costs $4.80 for the KDF60-XS955 but the techs will charge you over $300. You can do this yourself if you can get your hands on a service manual.

Hope this info helps.

Good Luck to you all.

ALSO:
I searched a Magnavox manual for the lock feature here is what I found...
The following functions are disabled during SDM (and enabled after leaving SDM):
· Parental lock
· Blue mute
· Hospitality Mode
· No-ident Timer (normally the set is automatically switched off when no video signal (IDENT) is received for
15 minutes).
All other controls operate normally.
Entering Service Default Mode
To enter the Service Default Mode, press the following key sequence on the remote control transmitter:
0-6-2-5-9-6-MENU
Do not allow the display to time out between entries while keying the sequence.
Upon entry into the Service Default Mode, the letters “SDM” will be displayed at the upper right corner of the screen.

ALSO:
- Line 7 : “CHANNEL BLOCKED”
Indicates that all channels are locked except the selected channel.
The following complaints may be generated due to locked channels:
- TV cannot be switched on from standby with the local keyboard buttons.
- “CH+” and “CH-“ buttons on local keyboard do not function.
To disable the LOCK feature:
Select ”FEATURE” menu (with the Remote Control).
Select “LOCK” (with the Remote Control).
Set to “OFF”

I have just bought a new wide screen Samsung TV but I can't work out how to switch it off completely. It always goes into standby mode


Have you tried pressing the standby button, and then the on/off button afterwards? Sometimes they need combinations of buttons, to work. It happened to me. I dont know if it will, but i hope this helps! :-)
