Question about Insignia IS-LCDTV32 32 in. Television
The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.
The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board.
I do not think it needs replacement, rather some defective capacitors are causing this issue.
Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.
The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)
You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.
What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).
You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors).
After replacing these capacitor(capacitors) most likely the normal operation will be restored.
Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.
If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.
I hope this helps.

SOURCE: insignia 32 in LCD TV: no signal
No signal.does it means in all modes...tuner, A/V and all other sources. If it does, you may have a faulty main pcb board. Call a technician.

Sorry to say but I believe you have what the rest of us have had happen to our TV's. There are three capacitors on your TV's power board that have gone bad. It is an easy fix and I only paid $5.16 for the capacitors required for the fix, but if you don't have the desire to do it yourself the power board is available on bestbuy.com for about $100. You can replace it easily enough with a philips screwdriver.
Make sure you un plug it first.
This seems to be pretty common with alot of LCD TV's from what I've seen here recently.
Good luck with it,

You can search for the exact manual at the database in this link. You just input the exact model number of your TV into the product search text box on the site at the link (as you have not provided this I cannot check it for you unfortunately).
Good luck and thanks for using FixYa.
