Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

It sounds like the on-off switch that my son destroyed at age 3 by constant on off. It was a Trinitron. It was still running at least 13 years later after I replaced the switch. But it also sounds like a voltage leak due to a high moisture environment. The high voltage leak pulls a higher load and causes a protection device to open the circuit etc until everything has dried out. If I had to guess, it is a flyback transformer causing the problem.

To select a proper universal remote control, you should know about the number of digits to its set-up codes. There are 3 digit, 4 digit, 5 digit, 2 digit and even single digit codes, to some brand devices. After confirming this, check the sites linked here. Both the sites have set-up code list and set-up procedure to many popular brand remote controls. Check which brand remote control has set-up code/s to your device brand, and buy that one according to availability? Brand name of the remote control isn't a matter, but it should have set-up codes in its code list, to the device brand you have.
Please note: Every new universal remote control will have set-up code list, and set-up procedure along with its pack. Never accept a remote control, that hasn't both of this. For more details about the set-up codes, visit the site http://electrohelponline.blogspot.com/ Check this site too. http://remotesearch.blogspot.com/ Type in the brand name of your device in the search box, and press "Enter".
Universal remote controls are available at most of the electronic spare part selling shops.

It is likely that the power supply is failing.

Sony FD... | Answered on Jul 19, 2014


You can try a hard reset: Unplug TV from AC mains and remove all cables from TV. Wait about 30 minutes and replug to AC power and redo the cabling. Switch on the TV and see if it works..

I would recommend going to the following link and getting the service manual so you can see first hand disassembly instructions and testing procedures. Its only 10.99 and they email it to you shortly after purchase. The manual is a valuable resource as it will have part numbers in case you do need a new board. heres the link.

hit menu button on your remote, navigate to channel setup menu. on the sub-menu, set channel fix to your channel that you require. now when your tv powers up this will be the default channel. if this doesn't fix your issue then try cycling through video inputs tv/video button on your remote.
