Power on problems

When I turn on my TV, the green light goes on as it should but then turns into a blinking red after a few seconds. The connections are all intact.

    Started out with the TV coming on, then would go to blinking red. Now the green light does not come on at all. I am an old tv tech with no experience on LCD TV's. I found lots of dust in the back of the unit and cleaned the fan and all openings. After cleaning the unit would start to power up, the fan would come on and then go off, and then the power light would back to blinking red..

    I have an identical problem that developed today with my LC-26GA4U.  Green power light comes on and screen turns on momentarily, then there is a relay click, and the red light blinks.

    is a relay click, and the red light blinks.

    I have hesitated to call Sharp, but seeing from this site that this appears to be a common issue, maybe they will have an answer?

This worked for me before, but now the problem came back after being fixed for months! unplug the two connectors at the back of the tv, the ones that look like computer monitor cables. then go to top of tv and use manual controls, turn off main power, then turn on while holding input and vol down button, a small service menu will come up, use the channel up down button to go to test, then push input button, there should be a box with reset and some number in red. use the vol buttons to reset to 0, then power off.... reconnect the cables and then turn on the tv.

Sony trinitron kv-es29m80 tv has no led light

The blinks are fault indication. If the standby light blinks 10 times and the set shuts down after that;
Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on the " D" board. If the transistors are bad, check R8051 and IC8005, also on the "D" board
