    This television stays on for about a minute - dims then just shuts down onto standby for no apparent reason. I have taken it away from the remote as I thought the sleep button might be stuck but it made no difference

Samsung T.V. goes on for 30 seconds then no picture


If this is a flat panel LCD tv, this is a sure sign that the panel itself is bad. I have seen this before. Tv comes on works fine then within 5 minutes goes blank.

Good Day, texxastam;

Do this:

1. UNPLUG TV
2. HOLD IN VOLUME DOWN &INPUT buttons on TV
3. Plug in the TV. (the TV will turn itself on).
4. A blue "K" should now be showing on the TV screen, release the buttons.
5. Press and release the VOLUME DOWN & CHANNEL DOWN buttons simultaneously on the TV. (A blue service menu will appear on the screen).
6. Using the remote, press the DOWN SELECT button once. (The highlighted line should read INDUSTRY INT (+CAUSE) OFF
7. Using the remote, press VOLUME UP once (OFF changes to ON).
8. Press ENTER. After a few seconds the screen turns green and shows - Industry INIT success - at the top of the screen.
9. Unplug the AC cord for 10 seconds then plug back in.

Good Luck, big IRISH.

PS; I did not make this up... it's from SHARP> again good luck...you may have to do this several times....too...get the timming down.

TV screen goes blank but power stays on


Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.

Sony LCD Projection TV turning OFF.....help!!!


Look carefully at the front lights. Usually when these sets shutdown they have a blink code on either the standby light or the lamp light. Update this with those counts. In the meantime, you may be seeing a problem with heat. If the lamp area gets too hot, the set will shutdown the lamp. Once the area is cool again, the lamp will fire.

Update this and we'll hopefully fix the both of them.

Sony KP-51HW40 51 in. Rear Projection turns blue


Hello......
First reduse the G2 voltage for the blue c.r.t,and watch if the unit works for longer period (offcource blue colour will be not present).After reducing G2 voltage to blue c.r.t still behaves the same than c.r.t is faulty and you have to replace.
Pls count the red led blinking when it goes off,incase it goes to std by mode.
