Tv Won't come on


I suspect a power board failure but to be sure i would have to know how many times your light is blinking as there is a code to it. please repost with number of blinks. This is a common problem with this brand of sony televisions as far as I can tell from what i have been reading online. If you are still under warranty you should contact Sony. If you need further help from an expert please let us know the number of blinks.

Hey there, I have a Sony TV and everytime I turn it on it will turn on for approximately 10 seconds with no picture but with sound, but then after that it automatically shuts off. The standby light is...


Hi slittle, my name is John. Welcome to FixYa. You have a power failure in one or more of the circuits. When you turn it on, it goes into standby mode, (safety mode), (protection mode). Sony has a blinking code they go by, depending on how many times the light blinks. Its called a Self Diagnostics Test. The TV will shut off to protect it from further damage. Count the number of blinks. Thanks for choosing FixYa...John

Our Sony tv is acting up....first it had no sound....then wouldn't change channels...now no sound or picture and turns off right after you turn it on?


I feel your sony is going to need another power supply in it or have the power suppply reworked. You might have bad eletrolytic capacitors in it that is causing this issue. That is what it sounds like when you said first the sound did not work then the remote did not work until total failure.

You might want to take that down to the tv repair shop and have them look at the power supply.

thanks and please do leave postive feedback and ratings for your free answer today.

I have a large projection toshiba tv. When I turn it on the red light indicator blinks but tv screen does not go on. Please help and let me know what I am doing wrong. Thank you.


one thing you may try first is disconecting the tv from ac outlet and plug back in ater 20-30 seconds, try to power back on. If nothing happens you're not doing anything wrong it might be that the tv needs circuit repair, the light blinks and you get sound indicateds a possible deflection board problem either horiz out transistor or surrounding circuit if you only get the blinking light no pix or sound could be also indicator of defl circuit failure or switching mode power supply acting up.hope this helps please let this site know if your question was answered.

The red standby light is flashing twice with a pause, then twice and a pause etc. There's no picture or sound and the light flashed whether we have the tv on or off. Any suggestions?


This blinking is a diagnostic code. Please update this with the model number. These sets contain circuitry that will shut the set down and display a code like this when a problem is detected. With the model number, I can look up the problem and provide potential repair suggestions.

Thanks,
Dan

Tv won' stay on


Sounds like your TV set failed the moment you decided to try the original remote....

But that remote didn't hurt your TV set.
It sounds more like your High Voltage or your Deflection circuit finally gave up the ghost....

TV won't turn on


There is a failure in the scan amplifiers, and or the power supply. This will require trouble shooting by an experienced TV tech who has access to the service manuals and know the set.

There are many components in the set that can cause this type of failure.

Did you not take an extended warranty???

This type of repair is not low in cost to have done.
