Replace the pcb convergence board,, It costs $96 and takes 10 minutes to replace you will have to manually line up your convergence afterward as the settings go to factory default. Everyone that owns this set has or will have to replace this part within 3 years

I have a Mitsi WS-65807 65" Played Wii for about two hours. Lost sound then picture. Now it wont turn on. Just get a warped bluish screen with lines. Any Suggestions?


Well i need more info. have you tried unplugging the tv for around 60 seconds? Was the "warped bluish screen" right before it died. Or is this when you turn it on it happens?(Bluish screen)? Because if no power at all and no picture at all. Could be Power supply. If you have some sort of picture with blue lines that are stable? You have a convergence problem. Get back to me with info i can help.

BLUE TINT ON MY SCREEN


Philips tv's have always had this problem. Between the picture tube and focus lens there is a layer of coolant fluid. The coolant fluid, over time, will break down and turn a brownish cloudy color and it usually starts with the blue. Something to do with the color frequency. Have a good repair shop check it out and if the fluid is the problem have them change all the fluid in all 3 picture tubes (there is a red, green and blue tube). Don't feel bad, like I said all the philips projo's had this problem. Thanks

Bluish color right coener


I'm afraid, it is problem of optics unit block (light engine), there are 3 LCDs red-green-blue for color picture formation and blue LCD sounds bad, please call local TV tech for fix.
Thanks.

Blue tint on rear projection tv


If this is a crts model , then one of the crts had blown, if it is a lamp rear projection, then it is a fault on the video circuit.

Screen is too blue


You will have to take the front cover off, usually 3-6 screws holding from the back, when it does come off there will be wires to the control panel attached still. you will also have another panel to undo. after that there will be a block with 3 focus controls and 3 screen controls marked b g and r for the three colors. The blue screen control is the one you are looking for, be very careful the slightesr turn has huge response including shuting the tv off when you turn it the wrong direction to far

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.

FADING TO BLUE SCREEN


Sounds like you have a problem with the blue gun in your picture tube or its drive circuit. You might remove the back cover and gently tap on the neck of the picture tube using a plastic screwdriver handle while watching the screen in a mirrow. If the picture flashes back on or on and off then the picture tube is the problem. If this is a projection tv you have three separate tubes : red, green & blue. you'd need to tap the blut one.Gently!!!! Stargazer
