Question about Sony FD Trinitron WEGA KV-27FV300 27" TV

1 Answer

KV27FV300 PIP Great TV for last 6 years. Today a sudden bright white flash on the screen; then an all white screen (but still with volume); then completely blank. When I plug it in or unplug, I do hear a click. I'm reluctant to pay a $99.00 fee just to have a tech tell me it's dead. Is it?

MY TV PICTURE HAS GONE A LITTLE DARKER AND ADJUSTING BRIGHT, CONTRAST, COLOR,ETC. DOES NOT HELP


How long u have this RCA analoge tv?Around 10 years or more and used it like about 5 or 6 hrs everydays?Yes,than ur tv it is losing CRT tube radiation cohetion.As times go bye years in years out the tv CRT-(tv tube) radiation will slowly dying out,Tv actual pictures will lost some of it luster and it brightnesses to the tv auctual pictures.Brightnesses of CRT tube will get darker and darker until the tv actual pictures barely it is watchable anymore.Contrast,Brightness and Colors adjusting more will help some.But u have to take this tv aparts and take a Flat scerw driver turn up a little bit more of the tv HV-(high voltage) SCREEN button on the FBT-(flyback transformer) to make any big differences of the CRT tube brightnesses.The FBT-(flyback tranformer) is the big block of plastic with a red wire with a black cap hook up to the tv CRT-(tv tube).This adjustment on of the FBT,HV-SCREEN button will help the tv CRT-(tv tube) last another year or two.

I have owned an emerson tv for two years now. All of a sudden the picture has become very blurry and white. It is not the cable connection and a DVD is also white and blurry. Even the input channels are...


you must open the back cover of tv, and then things you should do is set "SCREEN" adjustment on the flyback transformer. you must turn it counterclockwise to reduce and decrease the level of screen brightness. turn screen adjustment gradually until the horizontal blanking lines disappear from the screen. and blurred images will be sharp again

Brightness


The adjustment is on the transformer = it is labeled "screen"
for screen voltage.If the tv is working normally, you should not
have to adjust at all.My recommendation is to get the tv fixed,
not "mask" the problem with the screen adjust. The brightness
limiter circuit is suspect or the transformer itself. Any product
that has an electric AC cord attached is potentially dangerous
not to mention the physical removal / reinstall of the back.....T.

Flashes bright white randomly


resolder the tv circuit in the power supply and the flyback area that will solve your problem as the symtoms are intermittent just some loose components due to consistent heat over the years.good luck.

Need help with PIP


When you go into the menu to choose the PIP source the PIP comes on to confirm that a valid source has been selected. It is normal for the PIP to close when the menu is exited. To display the PIP normally you will need a remote with a PIP button. Most universal remotes today have PIP functions but if you get a Zenith original replacement then you are guaranteed to enjoy the other PIP features such as size, position, freeze and swap.

PIP won't turn off


I pressed "Demo" on the front of my TV and it worked, I have an old Sony KP-53XBR35 VIDEOSCOPE XBR - no original remote and the Universal remote has PIP button but would not shut it off.
Finally it's off!!!!
