|
My brother fell of the tv from a sofa, with small home service every thing was normal except discoloration. The board was broken, but it worked. Now after several month whole screen discolorised to pale pink, although color is still present. I took to sony maintainence jamal(kathmandu). They told me picture tube had gone or dying and they cannot fix it. Is it possible a broken picture tube still functions. Do i have to take it somewhere else or is it finished  |

| I own the exact same TV and it has the discoloration on the bottom left corner. It's a bright green blotch in the lower left corner. |

I've heard peole have used an electric drill to manually degause although I personally have never tried it but it may work as it produces a symetrical a.c waveform from the motor windings.
Anybody else tried it? |

Just a quick note before manually degausing or opening the set.
We used to get many phone calls if the set was moved or after a storm with these symptoms.
First ensure no magnets next to the t.v like hi-fi speakers and then switch off the set from the main mains on/off switch (not using the remote) or unplug from mains and leave for a couple of hours to cool and when you switch on again it should be o.k if not you may have to do it manually but I would assume the posistor is faulty as StarBaseONE2 suggests. |

Is this a terrible problem? What can I do? Will it get worse? How much to repair?
Any information, advise will be appreciated. THANKS!  |
I had the same problem and it was caused by the yoke slipping on the back of the tube. It took him about 15 minutes to get the picture fixed but he said the yokes on these seem to slip pretty easy.. Glad I have a warranty.. 
Do not degause the tube by any means other than the auto-degaus that happens when the TV is turned on. According to the repair man I had, he said the degausing of the trintron tube should only be done once per power cycle and it is done when the power is turned on.. Hope this helps. |

| Have you attempted a degaussing of the screen? If this helps trace down and check the the thermister near where the main A.C. hits the board. Maybe this will help. |
