This is a strange tv. It will not power on when pressing the power button. It gives me 7 flashes of the standby light then cycles the 7 flashes again and again. If i leave the tv plugged in it will turn on after a while all on its own. When it does turn on, the menus on the screen are missing any text. when looking at the video on the screen it seems to be slightly blurry. Any thoughts on what is going on? I have tried to find a service manual with no luck so far. Any kind of help would be appreciated.

Re: insignia ns-46e340a13 standby 7 blinks - when on, text missing on menus
Hi
can you post some pictures please when the tv is ON.
next step you have to take the tv apart and check visually if you have some bulging caps on power supply. -
Re: insignia ns-46e340a13 standby 7 blinks - when on, text missing on menus
There are no bulging caps. I have tested the voltages running from the power board to the main boards. CN901.
1 0v
2 5.2v
3 5.2v
4 5.14v
5 25.01v
6 24.97v
7 0v
8 0v
9 0v
10 12.19v
11 12.15v
12 0v
13 0v

You seem to have your ps_on but you lose your backlight signal. With your other problems sounds maybe like eepromI assume no responsibility for any stupid suggestions I might post.Comment

On main board U403 is eeprom. Probably under metal shield. You could try freezing it with air duster upside down and see if it comes on.

you can try heating/cooling the main board to see if the missing signals come back when in fault mode, or force the fault on when it is working.
looks like dskall beat me to this comment. :PWHY CAN'T PHILIPS USE PHILLIPS HEAD SCREWS?Comment

by salopianHello. I would need some advice please.
My son's MBP suddenly stopped working and is now only getting the green-then-orange light on Magsafe and no fan spin.
He brought the MBP into the house (22 deg C) from a very cold conservatory (-3 deg C) and turned it on straight away. The Mac suddenly died a few minutes later.
I examined the logic board and couldn't find any signs of water damage, corrosion, blown up components etc. Nothing was ever spilt on it, and the logic board looks immaculate.
I have already replaced the logic board with another... -

by sickboyI obtained this TV with a backlight problem which I've fixed, only to find out that although the TV works fine, all menus are blank with no text.
The background for the menu comes up with blank text boxes, and you can navigate these boxes with the remote, and I even managed to tune the TV in so the menu's do work, it's just that there's no text in them.
Is there a way to factory reset the TV? I've tried menu 4725 but the TV just restarts when I do this. Any help greatly appreciated! -
