Question about Insignia LCDTV26 26 in. Television
I fixed the problem with the "no power on, low clicking noise". The NPN transistor (2SC5931) was shorted. This transistor controls the horizontal hold. The shorting caused the power supply to overload and restart, then recycle. This was the cause of the clicking noise. Unfortunately this transistor was over $50, most likely due to the extinction of CRT's. I did find a replacement transistor 2SC5552, which only cost $2 (but I was able to get it in Mexico). The location of the transistor is located on the left side of the TV (looking from the back). Directly in front of it is the high voltage transformer which powers the CRT (should have a thick red wire). The transistor is attached to a large aluminum heatsink. To remove the transistor you will have to remove the entire electronics assembly to you can easily get to the underside. This was the solution for my TV, but there could be other components damaged.

I woke up this morning and noticed mine had the green light flashing- when i got home from work i tried to turn it on but no power, only green light flashing and a clicking sound every second, unplugged it for a few minutes- now i dont even get the flashing light.

This is an
indication that you have a short on the power supply section.It can't be fixed
by replacing the fuse alone. Short usually near the AC line where parts like
the following are present.
This is the common parts that might be shorted and made the fuse
blew. #2-5 is quite technical and need an expert to do the job so I've advice
you to look for a qualified technician to isolate the problem. You may visit
the link http://www.fixya.com/support/r8053361-fuse_keeps_blowing for more info.
Check also if your unit is under warranty, avail it because the manufacturer will fix it for free or a little charge only.
Hope it may help you.
Have a nice day!
