I have a blue tint to the picture all the time. Sometimes the screen goes all blue for a couple of seconds. This has been happening for about 2 months.

It appears that the HV tripler may also produce the screen voltage as is common on a lot of rear projection units. It is a common failure for the devider resistor circuit to fail. Somtime the resistors are external but often they are internal requiring the replacement of the tripler.

Picture goes off and on every couple of seconds


If you are hooked up to a HD source if the signal is too high will cause this to happen. Normally this will happen due to signal interuptions such as signal being low will cause freeze, too high will cause it to go out and cause the TV to show default blue.
Good luck to you.

Normal screen is white background, but lately I am getting a blue tint that clears up sometimes and sometimes not. Please advise


Try hooking up another knowng working monitor to the computer and see if the blue tint comes back intermittently.

If it still comes up then you know your video card is the culprit. If the blue tint goes away then you know the original monitor is bad.

Blue Tint


Most likely cause would be a loose solder connection that expands as the set warms up until it no longer makes a connection. You may get the blue to come and go by hitting the side of the cabinet after the set is warmed up awhile. (don't hurt your hand doing this, and don't keep doing it to "fix" the set. The connection will have to be located and repaired). Otherwise, there could be a component going bad, including the blue picture tube.
