Sorry to say, you need a new TV. The picture tube is bad, and allowing high voltage to feed back into the set where it shouldn't go. It would cost more to replace the picture tube (and probably the circuit board as well, as that usually gets damaged too) than a new TV.

Red, green and blue colours diveded on my TV


ok well "tube" tellys as they are called use an electro magnet to keep the picture stable and colours correct its called gaussing now if you have a speaker or something magnetic nearby it will stuff up the colors but only normally producing colors like purple,green, or white
if you have colors across the screen (that aren't caused by magnetic force) then you need to take it to a repairer or decide wether or not to buy a new one this issue can turn out to be quite hard to fix and can be expensive the different colored electron guns may be burning or burnt out causing pale color or it could be as simple as a power transistor in the H.V supply has shorted out..and causing power issues to the tube.
hope this helps,ben

Weird sound coming from the inside


Hi,
TV needs some kind of service and dust inside to be removed.
Regarding sparks sound, it can be leakage of high voltage of Fly-back Transformer. Qualified tv technician can check and repair it as high voltage risk is involved here.
Thank you.

Screen doesn't come on, but sound does!


Hi There!

Sony TVs are very difficult to assess at first, so one would first need to know how a TV works and then the experience that goes with it. Every model is different and has different faults that make them NOT work. I would recommend to have it repaired by a technician. I dont think this is something you can do with a remote or on the unit. It is internal. Good Luck, JUS004

Red screen


This problem occurs when there is defect in the chroma demodulator circuit. The usual symtom is a red or magenta color rastor with white retrace lines about 3/4' apart through out the display area.
In the worst case scenario, it could also be a defective picture tube. In either case, this is something only a qualified TV repair technician can service.
I hope you still have warranty left on this TV..

No! that is difinitely not an easy fix. there is something wrong with the picture tube. it is the part that emits light and colors. you need to bring that to a local repair shop.

Sony 34 inch Trinitron TV


uplug and open the cover and look for the red cable coming out of the picture tube. follow this red cable to a small board where you should see 2 black screws labled focus and screen. try turning these a notch and power on. it worked for some people but not for me...:(

WONT WORK *****


if you see near plug it might be due to sparking in socket or plug by calling electrician it might be repaired easily. But you have seen blue light in tv & chattering sound than it is dangerous. do not put on tv &call skilled person.

No picture / No Sound / No nothing


that sounds like the Hi voltage transformer went bad.. If your a tech simply disconnect the horizontal output transistor and see if thats shorted. If it is then it is for sure the HV transformer. If its not shorted look in the main power supply. Its cost is around 40 bucks or so and the transistor is about 15 to 20 bucks. This entire repair should cost ya around 150 to 175. So if you decide this tv is the one you like then have it fixed. Good Luck
