The sight in Jean's posting could help. Usually 5 blinks signify that the voltage is too low so you may actually have to turn the knobs up then back them off just until the retrace lines disappear. If one color dominates and you see retrace lines, you may want to turn that one down. But if the dominating color doesn't show retrace lines the other 2 might need to be increased slightly. If you Google Sony TV flashing led codes most likely you will come across an explanation of the codes. Hope this helps.

Please keep in mind many things can go wrong with TV sets and you should really do a lot of research before attempting any adjustment and or repair. There are high voltages present in some areas and they can reside even when the set is unplugged.

Screen fades to blue.


The Blue SCREEN setting is too high. These adjustments are located inside the TV behind the front panel. There are two screws behind covers and then a wooden panel to remove to access the adjustments. The leftmost set are for BLUE, the middle are GREEN, and the right are RED. The top row are FOCUS and the bottom are SCREEN. Focus will focus/unfocus the tube and Screen will adjust the power of that tube (there are 3 tubes, one for each color). If Screen is adjusted too high, horizontal lines will appear (my TV had red lines, but I played around with the knobs and saw that it could happen on any of the colors). Additionally, if SCREEN is set even higher than that, the tube could go so high that it turns the whole screen that color (in your case, blue). If this happens the TV will shut down, probably due to either overheating or overvolting. To fix this issue, turn the appropriate SCREEN dial down until the lines go away. In your case, you want to turn the lower left dial down. Don't turn it too far down, if you turn it more than necessary the TV can give you an AKB error (noted by the STANDBY light flashing a sequence of 5 blinks).

KP-51HW40 Sony 51" Fades to blue screen


The service manual on page 8 shows how to adjust the Red/Blue/Green screen voltages. To get to the adjustment board, take the front speaker grill off (two screws at the bottom left and right) and set it aside. No need to disconnect any wires. Then remove the plywood board with 4 screws that exposes the screen/focus adjustments. The top 3 adjustments are for focus, and you need not mess with these. The bottom 3 adjustments are for Red/Blue/Green screen voltage rough adjustments. My screen showed red lines, so I had to turn the bottom right adjustment with a philips head screwdriver just slightly until the red gun retrace lines where no longer visible.

Green flashes then tv turns off


or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.

TV Problem with shutting off by itself


Mine just did the same thing.  Except for it was green instead of blue.  The service manual states 8 flashes from the light stands for an overvoltage.  After reading the manual for a bit I realized the bottom row of 3 adjuster screws from behind the speaker grill adjust the output for the red, green, and blue colors.  BEFORE OPENING ANY TV OR MONITOR PLEASE KNOW THAT THE VOLTAGE INSIDE CAN KILL YOU EVEN IF UN-PLUGGED so please be careful and only adjust what is mentioned here.  I un-plugged the tv, removed the grill and the board covering the internals, and carefully turned the 3 adjustment screws all the way down.  I then waited about 10 minutes (don't know if this made a difference).  I turned on the tv, turned the channel to an auxilary input (for a black screen), and slowly raised each of the 3 bottom screws one by one up clockwise until i could see a faint green, blue, or red line (depending on the screw), and then turned each one back a hair until the screen was black again.  Only adjust one at a time, the order for colors are blue, green, then red from the left.  I hope this fixes your problems.  Be careful when working inside a tv,  I suggest not using a screw driver to adjust the screws due to the possibility of it slipping and someone getting hurt.
