Check its T'Con board's connection cables. If there is some loose contact to these connectors with sockets, this type of fault can occur. Check it first.

SOURCE: TV turns on for a split second then back to standyby

i think your capacitor is blown, do a google search for insignia, lcd, capacitor...
you can buy another one for about $2 but its a pain to install, you can also instead buy a new powerboard for about $80, its an east install and you wont blow more capacitors

SOURCE: TV Problems!

This is usually the high voltage on the inverter, balancer or backlight arcing to the chassis or at the connections. One quick fix was to look for a burn spot under the inverter(s). If that's the case, insulate the chassis at the point of the spot with a few layers of electrical tape 600v dialectric strength or better and carefully clip the leads just above the solder joint on the inverter board to widen the arc gap. If the white pink wire connectors arc too long they will charr requiring replacement. Cost varies depending on the problem.

SOURCE: blue light flashing

Possibly the power board or the sustain board has died.
Power board failure does not stop the blue light from working as this is an LED on voltage side of power transformer. The set fails because it has detected a voltage difference in one o0f the other boards that controls the initial starup and convergence. Some transistors and capacitors are also possibly involved. Not a dIY unless you are skilled. Parts $300 labour ?
but about $400
If you are a DIY get a kit from this site, complete with step by step instructions This is an LCD rear projection set.The yellow blob may be from the drivers to the LCD display, dirt or object on the projection mechanism, stain on the mirrors or lamp; bad projection lamp - among others.If you are handy, get inside the set and see if you can observe any of the items mentioned above.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. Viewing it in "Mosaic" or "Magazine" will make surf easy.

Hi! I have a 32" LCD led backlit bush tv (not sure


Yes, all the issues point to a problem in the standby power supply which runs 7/24 if the set is plugged into wall power--get it taken care of under warranty before it really fails bad.

My tv is on the fritz too.. Its basically doing the same thing. Im guessing it has the same capacitor problems all those others are having. Mines only 3 years old, paying 1500 for a now $700 tv.. Ive yet to find a price to fix it but nothings going to satisfy me. And all the talk sounds like samsung wont do a thing to help. Ready to invest in a good old am radio and boycott the tv industry. Sorry this wont help but I felt like venting.
