Four blinks denotes a fault with its main board. It will be best to contact any service technician in this case. If you're sound in electronics, check this link It has blinking codes details to many brand TVs. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic / Time slide, can be selected by the drop-down list, at the top left of the display window, will make surf easy. You can also do a search, by type in the brand name/model number/IC used, in the search box at the top right of the display window.

SOURCE: sony kdsr50xrb standby light red 3 times

If the STANDBY light flashes three times in sequence, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.

NOTE: You may have to replace the lamp also if the issue persists.

How to fix your gas furnice


most gas furneses have a red light on circuit board wich is located on intake. turn heater off then have someone turn it back on while you watch the circuit board. count the # of times the red light flashes before it pauses. it will flash in a cycle. for instance it flashe 3 times then pauses for 5 secounds then flashes 3 times again on and on. look on the back of the panel cover,their will be a diagram, in the diagram their will be dianostic report that will include what that # of flashing red light and what it means. for examle 3 flashing red lights ps stuck open. that means pressure switch stuck open. replace the part and your back up and running.
