Question about Sony KV-27V22 TV

1 Answer

Sony Trinitron color TV model no. kv-27v22

To the Experts,

My TV just recently began to have this problem (TV was manufactured in December 1997):

When power is applied to the TV and the power button is pressed to turn "on" the TV, the TV picture would come in for a little while and then slowly decrease in size from the bottom and work its way up to the top of the TV, finally disappearing altogether. Now, its takes a while longer before the picture will even come on - the "stand-by timer" LED on the front flashes a lot longer than normal now while waiting for the picture to come on.

Sound is working just fine.

Just a little history behind the TV. I bought it brand new in Feb 1998. It has been moved 6 times since then and each time a moving company has moved it. The TV also spent about a year and a half in storage during one of my moves. I didn't know if all of the moves / storage time could have affected the TV and caused this problem or not - It seems that the TV has operated just fine with all of the moves until recently when it arrived in Germany. The TV was being powered by a 1000 watt transformer that was transforming 220 volts 50 hz into 110 volts. I'm thinking this may be causing the problem because the rating on the rear of the TV calls for 120 volts 60 hz, which I'm not really sure that its getting from the transformer. Also, any idea of just how long these TVs are made to last?? I thought 10 years without any problems at all was pretty AWESOME, especially with all of the moves and storage time.

Thanks for your time and consideration in this matter!!

Paul

Dear, you can check that transformers out put before connecting to a tv. also when its connected to a tv.
get a avo meter and connect in series with a tv.
observe the current on the intial switch on and when the picture goes. if you notice that current on intial switching is high and then it starts going lower and lower, then change the transformer.
but if the current starts going up from the intial current then check the power supply components of the tv.
thanks for asking fixya.

Sony FD Trinitron Wega model KV-34BR800


Sony Wega Triniton KV-32FS100 TV

For the last week my TV has been going to a black screen for 10 seconds or so then the picture returns. It has been continual. Last night it stopped going to black screen, but now the standby light flashes 5 consecutive times and the color went haywire. A lot of red and everything that is suppose to be black is green.

I did a soft and hard reset with no success. What's wrong and is it worth fixing? Bought new in November 2002.

Sony Trinitron 29inch Color TV


The 2 blinks are an indication of over-current. This is usually because of a shorted component. The most common is the horizontal output transistor. This will be a 3-legged part attached to a heat sink close to the flyback transformer (part with red wire coming out the top). This transistor will be marked C4856 or something similar. Update this with the exact marking and I'll provide you with the full part number and approximate cost.

Sony FD Trinitron WEGA KV-24FS120 24" TV Color changes


Try turning down (off) the color during such an episode. If the image is tinted pink or green instead of black and white when you do this,you have either an intermittent short in your CRT (tube), which is terminal,or a gun drive problem, which may be repairable. If you're feeding it component instead of composite signal,it may just be a bad connection of the B-Y cable.
