Re: powering on and off

I must say this is a wierd problem here. First of all, make sure that the T.V. has enough space, and the cables arent layed on each other, give each cable its space. Now, try to check the main T.V. cable, is it strongly plugged in? because it should be, might be that your cable is weak and gets loose sometimes, so try to plug it in in a strong way. Keep me informed.

Kf-42we610 goes on but shuts off (sound and picture) after a few seconds. lamp light NOT on. Six years old. never needed maintenace. sometimes blinks five times

My thoughts is that there is an issue on the power supply board. Sony is one of the best serviceable TV's. If you find a TV shop that services Sony. They will be able to fix it. May not be the cheepest but they should be able to fix it.

Tv switches off and on

If lamp is good, Did you reset lamp hours? That should be done. Reset instructions are different for different brand tv's.
If you have reset the lamp hour counter, then test the ballast and the power supply to make sure they are sending out a constant voltage and current reading.

Resetting the TV
Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.
1. Unplug the TV power cord from the power outlet.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.

Hope it may help you;

Mitsubishi WS-55807 television

this tvhas a built in safety feature, fuse, sometimes you can hear a faint popping noise when you turn the tv on and it shuts down. This feature was designed to prevent power surges from hurting your tv any more than it already is. You will have to have someone repair the small problem you have now and reset the tv. 10% of the time you can try holding doen the menu button for 10 seconds and/or unlpugging it for 4 hours to do a hard reset. This hardly ever works though. It will probably cost you about 200 to 500 to fix it. sorry

Power problem

Most likely the convergence ICs are bad. These aare large black ICs attached to a heatsink. They will be marked STK393-110 and have about 15 pins or so. Replace these and check the fuses marked F9A01- F9A06 on the same board. Replace any open fuses after the IC replacement and report your results here.

Loss of Power

You might want to unlpug the powercord for the night, then plug it back in the next morning. Some times that can help reset things. If that still doesnt do the trick, you might have a faulty power cord. If it does this with every source you hook up to your TV then that would be a sign that its something in the set vs. your external source.
