White spots or dots showing up on your TV's screen could be the result of a bad or damaged processor or due to some overheating occurring the summer time or cold weather temperatures during the winter time. TVs can be affected by electricity surges or spikes as electricity supplies vary throughout the year. Or power outages and brown outs and black out can also cause spots to be on the TV screen too.
The standby light on a Sony television indicates when the television is turned on and operating, or turned off and in "standby" mode. However, this light also serves a secondary function: indicating when there is a problem with the television by flashing. When the standby light begins to flash, there are two reset options that can be performed to resolve whatever issue it's indicating -- a power reset and a factory reset
POWER RESET
1. Turn off your TV
2. Unplug the television from the electrical outlet. If you're using a surge protector or power strip, disconnect the television from the strip itself. Only by disconnecting the power cord from the outlet can you ensure no power reaches the TV during the power cycle.
3. Leave the television without power for at least 60 seconds. This gives the television enough time for all components to power down during the power cycle
4. Plug the television back into the electrical outlet. If you're using a surge protector or power strip, plug the television directly into the wall outlet instead. The surge protector may otherwise interfere with the power-up cycle, especially if it is old or damaged.
5. Turn on the television. If the blinking standby light continues, you'll need to move on to the factory reset process.
FACTORY RESET
1. Turn on the television.
2. Press and hold either the "Reset" or up arrow button on the remote control.
3. Press and release the "Power" button on the front of the television, while keeping the "Reset" or up arrow button on the remote depressed.
4. Release the "Reset" or up arrow button.
5. Allow the television to reset after the "Reset" message appears on the screen.
6. Make no adjustments to the television for at least one minute after the reset has completed. This is to allow the television time to finish auto-configuration and initial set up.
7.Turn off the television and unplug the power cord from the electrical outlet.
8. Wait ten seconds, then plug the television back into the electrical outlet and turn on the TV.
9. Follow all on-screen instructions to complete setup. These are the instructions displayed the first time you set up the television, for configuring channels, menu language, time, display properties and more.
Always include model numbers since problems are sometimes associated with particular models. This may be a sign that a line surge during power fluctuations has damaged the power supply. There are a least two supplies in any modern set; a small supply that provides voltage to the remote circuitry and this one is always on.
The second supply is the main one that is turned on when the set is to be used.
Reluctance to turn on is often a signal that certain components (capacitors) are failing in the main supply and they will continue to degenerate.
Try pulling the plug and leaving the set overnight without any power. If a circuit is only 'confused' (locked up) this should reset everything.
If it still will not turn on, then either the small supply for the remote circuitry was damaged during a surge or that the main power supply is not responding to the power on command.
Unplug tv and cable box.Replug both about an hour later.Still have the same problems.The power supply board is dead.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power supply for the replacement.
It is a fault with your power supply module actually inside the tv...take it to a local service center or if its under warranty take it back. surge protectors help prevent issues like this occuring due to damage to the power supply from surges but not having one wont cause these problems unless it has recieved a surge.....in future i would use a surge protector on all your expensive appliances, surges and power fluctuations are very common in mains power i live near the mines and we have power problems all the time!! hope this helps,ben
Leave the TV off and unplugged for 24 hours then try it. If it still doesnt work you may need to consult an engineer. The TVs power supply board may have blown due to power surge/spike. I recommend getting a surge protector to avoid this happening in future.
Your power transformer is likely shot. It'll cost at least $200 to have it replaced. Someone can come to your house to diagnose it. Usually costs around $65.
Yes, it's quite possible that you indeed may have sufferd from a Power Spike, induced by lightning during the storm, esspecially if plugged in during said storm. I have had quite a few customers ova the years with this exact problem. I always advise my clients to unplug ALL devices during a storm, and for ones that simply cannot be unplugged then some sort of Spike/Surge Protection device MUST be used. As a matter of interest, I have written many a report to insurance companies to support a claim for a replacement.
