    I have a 36 inch Sony Trinitron thats doing the same thing. Was hoping to find out how to fix it! I love the TV and don't want to toss it if it is something easy to fix!

    When the tv is turned on after a few seconds it switches to the view timer mode and the tv picture is lost. I opened the rear panel an began disconnecting and reconnecting wires thinking a wire was loose, well this worked for a month or so eventually started turning off again. Now I have no tv picture, and I'm out of ideas. I believe it has something to do with the power cord, but I'm no repair guy. I think I'd rather trash the tv before I call a repair guy because lets face it, they can charge whatever they feel even if the part are cheap or its a simple to fix. It's time to upgrade anyway, that flat screens been calling me. hopefully I can get some ideas and what to do.

I fixed mine with help of this site. I needed the 2 convergence amps and 1 resistor on that board was bad also. I done what Premtech said and that was to unplug the power to the convergence amps an turn TV on well it stayed on looked like **** but that led me to change the amps. Search google for a pic of these STK392-040. Then you can look at back of your tv they hook to the convergence board. Unplug the biggest connector on it see if it turns on. If it does you need both amps, and need a dvom to check the low ohm resistors on the board. Or take it to someone that can solder it all up and check the board. Also saw where the flybacks can have cold solder spot.

Sound goes off after 15 Min

Assuming it is not hardware but soft settings...
1) Check and make sure that your TV does not have the timer set.
The Timer feature allows you to set a day and time for the TV to turn on automatically and the device and channel to display when it switches on. If the TV is already on at the requested time, the TV automatically tunes to the channel you designated in the Timer menu.
When the Timer turns on the TV, the following message is displayed: "Press a button for the TV to stay on." Press any button on the remote control within five minutes if you wish the TV to remain on.
Note: The TV clock must be set before you can use the
Timer feature (see preceding page to set the clock).
Press down arrow / up arrow to enable or disable the Timer.
2) If not working, try SYSTEM RESET. Press SYSTEM RESET button on the front panel with pointed object (e.g. straight paperclip). TV turns off, green LED flashes for about 1 minute. When it stops flashing turn the TV on again. All settings other than Parental Lock need to be set again using the manual.
3) TV RESET. If all else fails for soft error. Your manual describes this last resort for soft type error. It could be hardware problem needing more expertise.

I have rear projection tv sharp 55u-wp7h. Unable to turn on tv due to view timer automatic turn on. what cause that and how to fix the problem?

I'm having same issue with same TV. It powers off after about an hour and red power light starts flashing. Only way to power back on is by unplugging TV and waiting a while, then plugging it back in, but then the TV will turn off again after a few more minutes, red light flashing again. I've checked the sleep timer and it is turned off, so any other solutions to this problem? All capacitors on power board look fine (not blown). I've read it could be solder joints in power board need to be resoldered.

Have the 6165wx tv won't turn on flashes 3 lights timer lamp and standby/temp any suggestions?

The tv's lamps life span is about 3,000 hours of viewing pleasure. Some lamps exceeds and some barely reached the 3,000 mark, but when this happened you will not have any pictures showing, but it have sounds. This means that lamp is already burnt out and needs to be replaced.

I cannot turn on the television, the word timer is flashing.

Start with plugging the unit out of the wall. Wait. Plug it back in and see if the green flashing lamp stops. If so, try to turn it on manually. If it turns on, go through setup again. If not, note the flashing pattern, it is a code for service personnel.

Timer light is flashing but tv wont turn on!

When the timer light stoped flashing the remote control would not turn on the TV. The next time the light quit flashing I held the power button in on the TV for about 5 seconds and it came on and has had no problems since then with the remote or the local TV power button.
