Tv turns right off seconds after turning it on, green timer light comes on and goes off, no picture comes on or sound

It could be your power supply board.

I'm having the same problem right now. I get the green light for about 5 seconds (not Blinking) then the light goes out. No sound or picture.

It seems that it has a problem in the feeding source I suggest him to check her

the timer is set for a short time, try to get to the menu quick and turn off the timer it may take several tries.

helloFive blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

Sounds like the digital board needs replaced.

you may check your lamp first. other than that i would say a faulty mains board.

after holding down the menu and device the led will blink a two digit error code such as 3 blinks pause then 4 blinks then repeat that sequence a couple of times. Need that blink code to help let you know whats going on. The 34 code means lamp abnormality which translates to the power Pwb capacitors have most likely failed.

I have a mitsubishi 48" integrated 1080. The Timer green light keeps blinking. I have no picture. Can this be the fuse? My coworkers say this might be the problem. Can I replace it myself? If so, where is it located?

check the collector drop on Q29a002. If it is less than 16 nano amps, repl ic u12 in conver circuit. stk392-570 and pico fuses f04 and f05 24v circ
