Hi and thank you for choosing Just Answer.
I am Tech Michael and I will be assisting you today.
Please be patient as these are technical questions that may require a bit of conversation to solve. Also remember to be detailed in your description of the problem. That will help me make a diagnosis quickly for you.
May I have the make, and model # ***** your set?
Also how old it is?
Customer: replied 1 year ago.

toshiba Lcd modal number 40bv700b about 4 yearsold

Expert:  MasterFixIt replied 1 year ago.
Thanks Dennis,
is there a pattern to the flashing light?
For example, a set of quick flashes and then a very brief pause before the pattern begins again? And if so, how many flashes before the pause?
You need to look at this carefully.
Customer: replied 1 year ago.

one flash then a pause 6 seconds

Expert:  MasterFixIt replied 1 year ago.
Hi Dennis, please try this.
Unplug your TV form power, next wait 10 full minutes then press and hold the power button on the TV (not the remote) for 20 full seconds then release it.
Now plug your TV in while holding the power button in and let me know if the TV resets and you are able to turn it on at this point or not.
If this works great then please rate my service kindly, but if not please do not rate yet but simply reply to me for further information;-)

michael we are now in the third day and still no joy i am not happy i am going out today so when i return i hope you have been in touch to let me know one way or the other what the problem is regards dennis

Expert:  MasterFixIt replied 1 year ago.
Thanks Dennis, we seem to have been on here at different times sorry for the delay. Usually I am here about 12 hours a day but since the surgery its been touch and go.
on this it sounds like your power supply is bad.
It may be simply a bad capacitor. If you have soldering experience you could replace the caps in the power supply, but if not it would be best to replace the entire power supply board.
Its easy to replace no soldering ;-)
I will help you make this swap. Unless you want to check the caps first.
If so, you are looking for the can shaped components if you see any with bulging lids or some that seem to have leaked a blue, brown liquid that likely dried on the can those caps would need to be replaced. They only cost a few dollars each;-) I will help you get them too if thats the route you choose to go.
But,
The best place to get that power supply is Sears parts Direct:(###) ###-####
I have other sources if you need them.
I will stick with you.
If you need me further you can reach me after rating at no additional cost until this problem is solved.
please be sure to give my answer a top-three rating.
It won't cost you anything to further to rate and I will be with you at no additional cost but you can always get in touch with me if you need further help;-)
Thank you Dennis I just had to be sure so I don't make you try parts that wont fix this.
Please rate kindly at this time and have a great day Dennis.
