RCA Model Number SLD65A55RQ Powers on blue then after few seconds turns to red and goes off? What can this be?

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: Screen goes all blue

if it is a KP65ws500 it is one of a group of sets made by Sony where all the picture Tubes(set has a RED, Green, and Blue Tube.) ARE BAD. Most of these sets had all three tubes replaced during a program Sony had. The tubes are NO LONGER AVAILABLE---the only way to get one is remove the tube and send it out for rebuild---most of these cost about 250-300 just for the tube.

The set is shutting down because when the screen goes bright blue it detects one of the CRT's(tubes) is pulling way to much current.

The problem with Replacing your Blue Tube is cost and----sooner or later the other two(red and green) are going to fail also.

best advice is maybe not to fix it.

I replaced dozens of the tubes in these sets when Sony had a recall and provided the tubes for free and paid for the labor etc.

I know I am not giving you good news but I do this here for free and if this has been helpful give me a vote here. Thanks!
