Have a Toshiba 42K81 Colorstream projection TV about 8 years old. Was watching TV and TV shut off. Now will not power on. Only get a blinking power light. Tried unplugging and replugging in. Tried all connections. Tried a different outlet on a different circuit. Tried unconnecting all components. Nothing worked.

I believe its the power supply board that has gone bad and needs to be replaced. The cost of repair will be around $200-$300 including labor if you get this done by a professional. As I said blinking light itself states that the power supply has gone bad. Please do accept the solution if the issue is resolved or else revert for further assistance.

May be you can take the back off the TV and blow all the dust off then inspect the power supply board and all the other boards for any blown capacitors however, still I would recommend to take help from a professional instead of doing it yourself just to avoid future issues. Please do accept the solution if the issue is resolved or else revert for further assistance.
