Sony bravia KDL-37XBR6 wont turn on at all, and blinks 6 times..


The 6X blink code is a bad back light error. could be one of the florescent bulbs in the panel if it shows a picture for a couple seconds and there is a darker band across the screen. Also Found loose connector CN6153 on the G5 Power Board.
CN6153 goes to CN6702 on the D4 board. Or the power board

I have a 19'' baird tv that is staying on standby.


your h.o.t. horiz. output transistor is more than likely shorted and this is how a switching power supply protects itself it does a self test and if parameters and current/voltage aren't correct this is what happens

standby light coms on when the tv is on standby - maybe you should switch it on via remote or on tv buttons, if there are any.

Good day,i have a problem on lg ctv model CF-20E60, STANDBY power after 10-15 mins, what's the possible trouble?


Hi,

You must look for its sleep up timer that might have been changed by someone. By restoring its setting you can get out of this problem. Other than this your picture tube may have some issues so if it is not dealt with settings go for a Tv engineer.

Please let us know if that was helpful enough.
Good Luck & Thanks,
Shiv.

Closed Captioning comes on every time i turn on the tv!


Apparently the 2002 Sharp model TV that I purchased has the closed captioning by default if the mute button is engaged. So there is no solution for my particular model, it has been built in this way. The only solution is not to use the mute button and lower the volume instead.

FAULTY TV SWITCH


Sounds like a fault in the secondary side of the power supply or possibly the Field/Line Output stages. Needs attention from a Technician.

My Screen Said "Are You Sure" and "Please Wait" and now, instead of "AV", i have "AV1" and "AV2" and my tv wont show picture from the dvd player OR vcr


You will need to go back into the menu and see what ia available in the video input mode. You may have switched the type of input you can use such as default or componts ect. If you have an isntruction manual, look in there or call the manufacturer, should also be in the instruction or user manual. Good Luck
