Re: Toshiba CF30E50 TV shuts off
Best first step is: Good visual inspection = look for hot spots
on PCB, check caps in those areas + solder any/all bad connections,esp. low voltage regulator pins.Look the whole
board over with magnifier = solder,solder,solder...T.

check that you have the battery in the correct way
if it has batteries like AA , AAA or what ever the negative terminal of the battery goes against the coil spring so if you have them all facing the same way, that may be why they are not charging
the screen shutting down at this stage would be cause the batteries are flat
of course you could always bet new fully charged rechargeable batteries and put them in correctly to see if the rest works
power light keeps flashing and the tv won't turn on. If you unplug for a
minute and hit the power button it sound like it is coming on then it
shuts off and the red power light flashes slowly. The TV is a Panisonic
1080i HDTV, about 6-7 years old.
Please unplug tv from wall socket for minute or so,, replug back in and turn it On. If tv still goes to standby itself than its standby light would blink to show an error in somewhere inside tv circuits. Let me know how many times standby red light blinking? There would be 3 seconds long pause in blinking so count pause to pause to determine problem section. Thanks.
HI, this is an emergency shut down, due to overheating. the yellow light is an indicator of a previous overheating issue that has damaged the power unit.
unplug the unit and, let it sit for 10 minutes to cool. after the cool off, plug the unit into the wall socket once more and, power up. if it continues to shut down and, flash the red light, this will confirm a major fault within the power unit. Contact Sony for the replacement of the power unit in this case.
***NOTE(If the unit begins to play normally after the cool-down period, you will need to purchase a cooling device to prevent future overheating issues).
If the blinking light on a Dell is yellow or amber or orange (somewhere in that color range) and continues to blink the entire time it is plugged into AC power (wall outlet) and when you unplug it from the wall the laptop immediately dies .... then you battery is dead and needs replaced.
If the blinking light stops after a while (perhaps a minute?) and then turns green while plugged into AC power, then it is successfully charging - or so it thinks.
When you unplug it from the wall, does it stay up and running? If it runs, it's OK - just ignore the light and plan on getting a new battery one day, start browsing now. :) If it dies immediately upon unplugging, then your battery is dead and needs replaced.

tv shuts off for no reason...red light blinks 4 times ...stops...blinks 4 times....stops....etc....what can i do before taking it back??
this is a brand new unit....fantastic picture....fix my problem
The first thing to try is to unplug the unit from the wall for about 15 minutes,if this does not work you will need the assistance of a servicer to diagnose the problem,if you are familiar with tv service you can check the horizontal output transistor for a short,sometimes it fails for no reason and other times it goes bad along with the horizontal output transformer also know as flyback.Be careful if you decide to check this yourself.
