Refer to owners manual ! Blinking indicates the type of fault that is occuring on all your tv sets. example : power light on red - indicator light beside it green but blinks rapidly for half a second rapidly then shuts off. This refers to a faulty lamp or a lamp that is near its expiration. Read your manuals if indicators refer to easy repair sweet, but if it says call tech then bummer...

when both the blue light and red light are blinking it means 1 of 3 things. 1. lamp replacement. This often works everytime for the repair. TIP!!! DO NOT USE ANY OTHER LAMPS OTHER THAN JVC AUTHENTIC LAMPS. ANY OTHERS AND YOU RISK DAMAGING YOUR TV FURTHER. 2. the fans are not working properly or need to be replaced. They need to be cleaned every so often and they will stop working from burn-out if not done so. This repair will cost you less than 100 dollars. 3. The ballasts are defective and need to be replaced. The ballasts themselves run about 150 dollars. I tell you I have fixed this TV more times than I care to count, not to mention the number of lamps I have gone through. The guy at the TV repair place now knows me by name when i come to buy lamps. :(

Your owner's manual for the television will contain a troubleshooting section that will describe the blinking codes for the various lights, and what they mean.
However, in your case, it probably means the light is burned out.
The bulb on my TV tends to burn out about every 16 months (I watch TV for many hours per day, so your experience may be different). If your TV is still under warranty, I would suggest you contact the store where it was purchased, or contact the manufacturer.

There are three fans the one that usually fails is located on top of the optical block and cannot be reached by the owner unless you take the set apart yourself. What is happening is that one of the fans are not spinning fast enough or has stopped altogether. The best solution is to replace all three fans cleaning may not be enough to get a slow fan up to speed, and the tech should blow out the dust in the duct work. This is what the tech coming out will (or should) be doing. Also some fans will have an intermittent startup, and cause this intermittently, so it is a good idea just to replace the fans instead of just cleaning them.
