These 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. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.

I keep getting "no input signal". I have a small 32" Visio as a spare and it works fine using same cables, box, etc


try selecting the input source on your TV to the one you are using, sometimes auto-detect doesn't seem to work properly. This can be done by the remote control, or the buttons on top of your set.
You might also try changing the physical input socket, eg to the RF in, SCART, HDMI etc (you will probably need different cables for this), but if your set is selecting another source you will still get this message.
Also you might try using a different input device to check your TV, although this is unlikely to have any effect because the input devive plays on your second set.

Wheni push input, i get the options but no arrow i push will move down to option to play vhs


not enough info , if your trying to change the tv input , make sure you select tv on the universal remote first , you either need to keep pushing input til it moves down to your desired input , or use the arrow key to move it down to the input. some require you to hit enter or ok to select , others just wait a second , it should change. if your getting the options menu when your hitting input , then the remote is not compatible with your TV / VHS / DVD...
If you get the input to change and your successful , make sure you hit VHS in order to call a command , if its still in tv mode , your only going backwards , make sure whatever your trying to control , the remote is selected to that device ... Good Luck ..

HDMI connection


You should have an Input selection on your remote, keep pressing it until HDMI is high-lighted and that should be it. The other method is going into the menu under input and select HDMI. Let me know?
