Found out from Toshiba that the yellow flashing is the cooling fan has stopped working. Replace that and you should be fine.

I just want to remind you that the average surge protector is only good for the one hit

Insignia quit working after storm


Check the fuses on the power supply board first. They usually blow when you get a power surge. You may be able to replace them and get the TV running for a few dollars. If the fuses are good then the power supply board will be the issue. The main board should not be damaged because the surge has to go through the power supply board first.

I have a Mitsubishi projection model WS-B55 that is plugged into a surge protector. The power went off for about an hour or an hour and a half this morning, and the power light is flashing. I called...


First, to answer your last question, not all power outages and subsequent surges are created equally nor are all surge protectors. Also, after a power outage where the subsequent surge is so strong that it got past your surge protector and knocks out your TV and it's never done that before... REPLACE YOUR SURGE PROTECTOR.
However, that being said, in my experience it is unlikely that the TV is going to require a technician. Understand that the person that you spoke with in tech Support is not a technician and is reading off of a list of troubleshooting pages that are more extensive then what's in the manual. What the technician is probably not aware of is that your TV, like most home electronics, has a safety failsafe that requires the device to be separated from power completely before doing a system reset
First, after pressing the button it's supposed to flash for about a minute anyway but I'm assuming that after it's done pressing that the TV is still not firing up.
Unplug the TV, let it sit for an hour, plug it back in (to the wall, not the suspect surge protector). If the light is still flashing, press the reset button again and wait for it to stop flashing and attempt to turn it on again. If it doesn't work, unplug the TV, follow the same steps however, let it sit for 24 hours before plugging it back in. That length of time is not common but some sets do require it.
If none of this works, then I would say that it's time to call a technician.

Recently there was a storm in my area. Satellite quit working then TV went out. TV is on a surge protector and nothing else quit working but tv. The power light blinks and nothing can be done to make TV...


Usually the blinking indicates a power section problem. That could have been from a power surge. Thats a shop job to fix. Since its out of warrenty you need to get an estimate first. Repair costs can be more than a new tv. Last one I saw was $450ish. If you have any local tv repair shops talk to them , then talk to sharp and get contact info for the repair depot and talk to them. Get estimates from all, then compare that to a new tv cost and you will know which way is best for you to go.

Unless you spent almost as much on the surge supressor as the tv they are only actually meant to protect the wiring in the house. The do not react fast enough to actually stop a power surge. They just cut off a short circuit problem so the house wiring doesn't overheat and burn the house down.

Turn on system, it flashes green than a yellow flashes then to red flashes. i have unplugged everthing even shut down power towhole house...and nothing.


Yes this is the red/yellow light and you will need to get it fixed, it is not a power surge unfortunately!

It is the motherboard taking too much heat!

You can fix it at home with a top guide or send it in.

Having the yellow flashing light


Sounds like maybe a power surge killed the TV. If it is newer, try contacting the Manufacturer for warranty repairs.

I like ones like you who already understand that a lightening power surge can really kill the computers will to live lol

1. always put the computer on a surge protection strip or even better a UPS backup device to protect it from surges , and in the case of brownout the UPS backup would take care of that circumstance
or at least some kind of VR , voltage regulator ... not that computer powersupplies do not protect the PC , the PC powersupplies of today to have some built in protections , but ooops there went your power supply anyway if you know what I mean.

2. if you suspect the power supply is the culprit , you can test by using another power supply
which is a good investment because if it was the power supply you just got yourself a nice new one
and even if it's not the power supply , you still have a nice new one in your hand

a power supply in the hand is worth two in the bush :-> lol

and if it's the motherboards fault , at least you'll already have your nice new power supply for that new motherboard you get.

a good strong power supply is a good investment no matter how you slice it.

I always keep any spare power supplies I get , because you can use them while your dead power supply is being RMA-ed or sent back. ,, that time gap is not fun lol

shalom
