Hi Sanuj, what you say is that, an LED turns Red and then Green like this alternately?
Indicate your sharp TV model you are commenting on, in order to find the best possible solution
I wait your answer

If it’s a CRT set, sounds as if the blue gun on picture tube has gone out or carboned up. It could also be a problem in your video section or the board on back of picture tube where it plugs in. You could try to use a good electronic cleaner and a q tip on the socket pins on the back of picture tube. UNPLUG IT and don’t touch the wire or connector that goes to the top it the crt tube! Allow it to dry for at least two hours before you plug the board back on the tube. BE CAREFUL!! Go easy when unplugging and plugging in that board! If this doesn’t help you would need diagnosis by a qualified technician.

The 392-150 is a higher current device then the 110---you can use either--this is normal in the hitachi sets---I usually replace both with 150's---check the led that does not light---should indicate which voltage source is bad---if it is one of the 2 voltages for the convergence ic's(one is a positive and the other a negative voltage) then the convergence Ic's may be bad---look for any discolored resistors around the ic's---one way to tell if it is a convergence ic is to de-solder both ic's and see if the set turns on(the convergence will be out the window) but if it comes on change both and do the alignments with the Hitachi remote. By the way----the led should have a location number printed on the top of the circuit board.

led goes from red to green and back to red when turning tv on
SOURCE: Green led indicator light is off on my 62" toshiba
when you turn it off your light blinks because your internal fans are still spinning allowing the inside of the chassis to cool off, hence the reason you dont watch a DLP TV and then unplug it. DLP's are JUNK

not a solution but i have a 50gx30b doing something similar, no picture no sound, 3 green leds are lit up on the main board and then one red led lit up also on main board, front panel red led stays on for about 30 -50 seconds and then it all shuts off, I then have to unplug and replug to get the same results.

This ia an old CRT TV, THERE IS NO POWER SUPPLY BOARD BY ITSELF that you can buy! I sure like to see this 'POWER SUPPLY BOARD' from TVPARTSANDMANUALS.COM!
The main board has power supply, controller, Flyback xformer, etc.
You need to do in-depth troubleshooting, check the H.O.T, Flyback xformer, caps, etc.
