Your television is very likely stuck on a diagnostic cycle which is normally only used at the factory and by repair technicians.

You will need to contact the manufacturers customer care/service department to find out how to get the tv back to normal; I cannot tell you who to contact as you haven't stated the make and model nor which country you're in. The information won't be in your user manual as it's not a mode which customers are ever meant to be able to access.

Turns on for 30 sec then goes bright blue and goes back into standby. turn back on it does it agian


This is blue CRT problem in tv as it is rear projection tv that has three CRTs red-green-blue inside to project color picture on front screen.
Blue CRT (tube) will be replaced to fix the issue and it is job of Pro because lots of adjustments are required after replacement of tube.
Local tv repair shop will help you for that.
Thanks

My Sony KP-46WT500 screen shows the tv image in blue only for a few seconds, then it goes completely blank (as if it were off). Do I need to replace the bulbs?


It is rear projection TV that use 3 picture tubes of red-green-blue to show color picture on tv front screen.
Do you see standby red light blinking when TV shuts off after showing blue image for a while?
If red standby light is blinking, please count it how many times it blinks, there would be 3 seconds pause between blinks so count pause to pause and post it here to find out possible solution.
Thanks.

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!

Display has red tint across entire screen. Could it be the bulb? If so, is that still available? Approximate cost?


two possible solutions----either a problem on the small circuit board that is connected to the RED picture tube OR the red screen control is turned up too high. These sets have a small square block with RED,Green, Blue screen controls(same place also has red, green, blue Focus controls) if you remove the speaker grill you will find an inspection plate made of masionite---the focus/screen block is visable behind it----get a flashlight and look carefully at the block---one row of 3 plastic shafts is Focus(don't touch those) the other 3 are Screens(you should see R, G, B marked) go to a blank video input(one with nothing attached) and turn the RED SCREEN CONTROL JUST SLIGHTLY TO THE LEFT UNTIL the red goes away.

Red,green and blue lines across screen


I f these lines are slightly diagonal and they all showed up at the same time. you probaly have an open resistor in the ABL circuit. since your set is 13 yrs old, I would not put a penny into it.
You might take the front grill cover off and the panel behind it and find the little black box with 6 little controls 3 are for focus 3 are for screen turn the screen ones ever so slightly counter clock wise. the control in the middle is the green screen adjustment. If the green line goes away try the one labeled r for red and b for blue.
