Damage to screen during power failure

Our 5 year old TV screen (cathode ray tube I think) was damaged during a power failure. It appears distorted and cannot be adjusted. Also the colour cannot be adjusted and is very poor. Would this be able to be repaired or do we need to replace the TV?

Yes, worth fixing. A techie may be able to do a "degauss" on the screen and get it right again. This is the removal of residual magnetization of the cathode ray tube that is done by applying a fast alternating magnetic field to the screen. Sometimes the symptoms you indicated (though a bit vague) imply that the degauss circuit of the TV itself has failed. Voltage spikes are known to often do that.

How to degausse gpsmap 172 gps

Hi Donnie,

Degaussing is not something that ever needs to be done on this device.

Degaussing is a term that I learned many years ago - it was a process performed periodically on early CRT (cathode ray tube) displays (such as a TV). Over time, CRT displays would build up magnetic charges that would cause the image to become distorted. A degaussing wand would be connected to an AC outlet and then brought very close to the display and gradually withdrawn. This would neutralize the magnetic charges on the display - and the resulting distortion. Years later, manufacturers incorporated a degaussing coil inside the display's cabinet that did the same job as the degaussing wand - thereby making the wand obsolete.

The GPSMap 172 has an LCD display that requires an electrical charge to create an image on the display. Unlike a traditional CRT type displays, an LCD (or LED for that matter) display is unaffected by magnets / magentism. Hold a magnet near a non-CRT type display to see for yourself. A magnet held near a CRT display however will distort the image more as it gets closer to the display. Caution: Doing this may cause PERMANENT damage to the CRT display. This is why many home theater speaker systems touted that fact that they were "magnetically shielded" so that they would not distort the images on the CRT display.

I hope this helps!

Sony Trinitron TV now taking around 5 minutes for picture to appear (sound comes on instantly) Is it worth repair or should I cut losses and replace set?

How old is the TV?
Sony Trinitron sounds like it may be from the 1980's?
Some TV engineers can use a piece of equipment to do a "tube boost" but this is sometimes risky and can completely ruin the tube, but it's a risk you would have to take.
If the TV is over 15 years old, and has been used regularly, (like 4 hours every day or more) it seems likely that the tube has reached the end of life.
TV cathode ray tubes are like light bulbs...they do not last forever!

Black line down lefthand side of screen about 1" thick

The monitor is old. It could be slightly adjusted. But when you start getting lines, soon the image becomes blurry, and during CRT death the Cathode Ray Tube radiates 100 times the radiation of a healthy monitor.

I have a Sylvania SRT2227S with video rollover a the top of the screen.

I am unfamilliar witht this model however it appears to sound like a Cathode ray tube Television , roll over is caused by a fault in the vertical frame output stage if it is an old Hybrid set it will probably be a vacum valve that controls this ( however havent seen this type in 20 years all transistor and intergrated circuit outputs now ) and repair should be undertaken by a qualified engineer . if an engineer is not available then someone with electrical knowledge and safety precaution training as the insides of these type of televisions generate lethal voltages at several points in the system . The coils around the tube base are the deflection controlers and they control the size and shape of the picture depending on the voltages and positioning of the screen mask's to shape and stabilize your picture . Any one touching these without the correct tools may damage the set further by distubing the convegence settings , in short I suggest that this is a job for a trained TV technician ...
