The main power supply of the set may be faulty, and or there is a fault condition on one of the other boards, and the main power supply is going in to protect mode.

You might want to talk to JVC as this model had all kinds of issues--missing any color, picture inverted or backwards just to mention a few.

The solution was to connect it to a computer and use a jig from JVC and download two up grades on sd cards and install them manually.

I mention this as the Light engine in the set communicates with the main chassis and you in fact may have a issue with that.

At least make a call to JVC---saw about 40 sets with this model where this cures all sorts of communication issues--the engine if "set" wrong could easily cause this problem.

Lamp button flashes on and off


Suspect set has a bad lamp---light is there to indicate lamp or something associated with it has failed.

Lamp life varies but is usually 2,000 hours or 2 years average use.

Replaced lamp in my HD 61Z575, but when I turn on my TV, nothing happens (no fan noise). After ~10 seconds, the Light LED starts blinking rapidly. Could it possibly be the brand new lamp? Ballast?


The old lamp was in there before the fan work?U replaced the lamp u put the door back on did u make sure the safety latch is off and tightly closed with the the lamp door.The continue blinking LED light does it make alot of clicking noises too.Yes,then the Ballast board it is dead too.The Ballast board only job are to help the projection lamp to ignite to work.

61 inch projection tv flashing on and off


The most common problem with JVC LCD rear projection TV is bulb failure. Do not panic, this is normal after 2-5 years of use.

You can change the complete assembly or for less cost just change the bulb. Do not use Osram or other funny brand "rebuilt" or locally made bulb. Use a Philips replacement and all should be good.

Changing the bulb involves removing the lamp assembly and taking it apart like a puzzle and replacing the bulb. JVC are a little more difficult to do than most others because the wires on the original bulb are molded into the glass on the original bulb. Wires must be cut and stripped of insulation before connecting to the new bulb.

All JVC LCD Rear projections TVs use TSCL110 TSCL110U TS-CL110U Lamps.

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. :(

NO PICTURE OR SOUND


Hi
Usually, if the red light is flashing and you get no picture, that means that the lamp life cycle is finished and you'll have to get a replacment lamp. the lamp has about 3000 hours of life (2 to 3 years under nomal use).

You can buy a replacment lamp from here
