    Toshiba 28Z33B. Standby light on but cannot swtich it on with remote or by Tv controls (although TV controls are limited). Worked for a day when I kept trying but now won't turn on at all. When it was on the volume could not be adjusted (saw "locked" appear briefy on the screen a few times when I tried to change volume)

    I have 2 tv's one Sony 27" and RCA 32". I have had them both in my sunroom where there is no heat or A/C. Each time I have placed one of the TV's in that room they stop working. They Will not turn on by the power button or remote. The TV's are only about 4-5 years old and have previously been working fine. Please help.

Turn on tv blue light comes on.screen stays dark .nothing happens .tv would come on after 10 minutes thenit started taking longer. now not at all.

Hi there,

Well first of all you can tell us the Brand and the Model number of your TV? and tell how old is your TV?
Anyway you can try to reset your TV first unplug (switch off) your TV for 24 hours and then turn it again........... let us know if further you have the same problem.......

Good Luck!!

1995 toyota 4 runner starting problem once in awhile

Is the starter turning over the engine when it wont start or is nothing happening at all?
I might have your solution if I have more details.
If the engine is turning over but not starting then switch on the ignition and push it to start.If it starts you probably need a new ignition switch.

Please get back to me .Thanks

Tv wont turn on

take your tv to technician who can check your power supply, if your power is coming on and off, than a problem is not as big. firstly let him check a ht of a supply constantly, your supply is cutting.

Tv wont turn on

I had the same problem and took it apart. Before the repair there was no "click" when I pushed the button, a clue to the problem. The on-off button on the front pushes a weakly made angle piece of plastic inside which had broken. The plastic piece in turn is supposed to push an internal switch which is offset to one side.

I used epoxy (Araldite) to repair the broken plastic angle piece, but it still looks weak to me so I switch the tv off at the wall and leave the on-off button alone (though it does work now).

Opening the case requires some knowledge and care, and can be dangerous. It may void the warranty so be careful or give it to a qualified repair person.

Hope this helps!
