SOURCE: Projection TV keeps shutting down

I just took my Mitsubishi WS-65315 65" in to be repaired for the same problem and was told that it needed a new main circuit board part number 930b899005 as was told they wanted to charge me $1100.00. So I told them not to do the repair and picked up my tv and found that same part at Sears parts for only $225.00. Some of these TV repair places are theifs.

SOURCE: screen tuens blue them tv turns off

NOT GOOD NEWS... IT SOUNDS LIKE YOUR BLUE CRT IS SHORTED. THE ORIGINAL PART IS N.L.A.(NO LONGER AVAILABLE) THEY DO MAKE A GENERIC REPLACEMENT, BUT I DON'T THINK THEY ARE AS GOOD AS O.E.M.
YOU CAN TAKE OFF FRONT OF T.V. AND ADJUST THE SCREEN DOWN ON THE FOCUS BLOCK. IT IS THE BLACK BOX WITH 6 ADJ. ON IT 3 ARE FOCUS. 3 ARE SCREEN . TURN THE BLUE ALL THE WAY DOWN , THEN WITH THE BACK OF A PLASTIC OR RUBBER SCREWDRIVER HANDEL YOU CAN TAP ON THE NECK OF THE CRT, NOT TO HARD. SOME TIMES YOU CAN CLEAR THE SHORT OUT OF THE CTR. IF THIS WORKS LET THE SET WARM UP FOR 10-20 MIN. THEN TURN THE COLOR ALL THE WAR OFF, THEN SET THE BLUE LEVER UNTIL YOU HAVE A GOOD BLACK AND WHITE PICTURE. BE CAREFUL NOT TO TURN IT UP YOU CAN DAMAGE THE CTR IF THE LEVEL IS TO HIGH. ERROR 8 IS A.K.B. ERROR THAT MEANS THE CRT'S ARE DRAWING TO MUCH CURRENT.

SOURCE: TV turns off anf on

I finally got this problem fixed. I posted on another forum and found that when a bulb starts to go bad it can cause these TVs to do strange things. You can replace the bulb for less than half the cost of replacing the whole housing. See how here: www.geocities.com/bob_lipp

If you have Hitachi model number 50UX58B, 60UX58B, 50UX58K, 60UX58K, 50SBX78B or 60SBX78B and you have the following symptoms you may want to grab a repair kit from www.TvRepairKits.com. They have put together a kit that includes the parts and instructions to fix these models. This is a fairly common problem with the above model numbers. It is typically caused by a blown capacitor and pico fuse. Again, you can get a kit from the above address. 
Here are the symptoms...

Primary Symptom: No Audio or Video. Power light will come on briefly then shut off.
Other Possible Symptoms : The green LEDs on the circuit board light up for a few seconds then turn off.

Hope this helps,

SOURCE: TV shutting down

Probable main power supply failure. In all modern sets, there will be two power supplies; one that keeps the set enough alive to respond to the remote and a second one that does the 'heavy lifting' supplying several regulated voltages for different subsystems. This latter one has failed.
If you can locate the main supply board, it may be fairly easy to remove to send off to the factory for repair.

TV click on and off.When it come on it has a green screen with lines. Stay on just for about 3 sec. than click off.


The green crt is dawning to much current, and that is why the TV is shutting down, if you remove the speaker cover, there is a focus block, that has six controls, on it three are for red blue, and green screen voltages, if you turn green down where the retrace lines go away, the TV should stay on, it is not worth fixing, you would be better off getting a new LCD.

Replace a projection bulb on a RCA D52W23?


Hi,
I have this tv.
pull it out and start undoing the screws towards the bottom half of the tv around the back, get the speaker grille off and then in there is your access cover for your bulbs. theres three of them red blue green. the bulb assemblies and circuit boards are integrated 3 bulbs -three separate assemblies. you will probably have to turn the tv back on when its disassembled to see which bulb went.

Projection TV keeps shutting down


Good Day;

Sounds like you have a bad green picture tube that has failed. To check this out; remove front speaker grill, remove small panel, you will see three CRT's (pictue tubes) sticking down, remove the little board on the middle tube then restore power. If TV stays on more then likely the CRT is bad but not always the driver on board could also be bad, check voltages.

Good Luck, big IRISH.

KP51ws500 turns green and shuts itslelf off


There may be several causes but, one is that when any color gun is being over driven, the Sony shuts down the gun to protect it. Try this. Remove the front of the set by removing the two screws from each lower corner. Next remove the black panel held on by 5 or 6 screws. Now you should see a panel with 6 potentiometers on it. Turning the ones on the bottom row CCW reduces the drive. Turn the color down and if all the guns stay lit, SLOWLY turn them up until you get the color balance that you like.

Green picture


you might wanna look into the "flicker issue" with your set...If you've had it for a while a could be that it's just worsened over time and developed into a voltage leak. I have the same set and it went undetected for a couple of years due to poor quality cable signal..once I went to a clear signal (ie. directv) the issue was very noticeable, but by that time it had progressed. Eventually one of your guns will fail and the set will stop working all together (mine did just under 4yrs from purchase) and unless you have Sears warranty that WILL try to stick it to you. TRUST ME!!! Good luck.
