Insignia NS-LCD47HD -- No Picture but I have blue power LED

[dr_jared88]

Hello Everyone!

Long story short (no pun intended), my idiot dog chewed the power cord to my TV and I believe it shorted something in my TV. After replacing the power cord I get the regular power LED (Red standby, blue powered on) but absolutely no display. I have checked with a flashlight to verify it's not a back light issue.

I opened the TV up hoping I'd see something that stood out as wrong like a blown capacitor. All I really found was a thermistor that appeared a little burnt but I believe it is still working.

Any ideas on what the issue might be and what I can check? Any help would be greatly appreciated!!

Hi - if you have a steady blue light fuse should be ok.
Do you have a multimeter.?

If so with the power on can you test the voltage across the two BIG caps
CARE HIGH VOLTAGE - Meter on 600VDC or DC multirange with the TV plugged in
put red probe on positive leg of the cap and black probe on negative leg and report
result. Press the power on button and do the test again. ( May be even higher voltage!!)

Sent the manual to tom66 to host. In the meantime... here is a snapshot of the flowchart for a "no power" scenario, but it states the indicator light would be "green" not the blue you're experiencing.

Perhaps it's a typo... in any event..
