32 wega trinitron

My picture tube is getting weak, from your post and by the way thanks for that post. Question, I fall asleep to the tv. Does this shorten the life of the tube versus turning a tv on and off. Our tv is about 12 years old and is this an average life span of a tv in todays world. thanks in advance for your help and its valuable to have someone such as yourself helping others troubleshooting problems so thanks!

My triniton wega tv 32 inch flashes 5 times and i lose the picture then it comes back on lasts awhile then lose the picture again flashes 5 times again over and over


you can ensure the connection and Heater's voltage, start from Flyback transformer ( Heater Pin) to Heater of the CRT tube, whether exist and normal ( Include : check Resistor in Heater area), perhaps there is lost connection for a while and connect gain. There should be 5 Volt AC available. otherwise check the socket of CRT Tube, unplug and clean it. If there is any question you can ask me and clarification with detail result from my solution.

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!

Screen goes black every few seconds but have a picture


Sony incorporates a video blanking circuit that blanks the picture out when the picture tube begins to get weak. sorry, but short of replacing the tube, there's no lasting solution to this problem. I used to have some success rejuvenating the crt, but I found that it didn't last but a few hours before the blanking circuit starts to activate again.

Standby


I think your picture tube is weak.
You can verify this by taking the back off and slowly adjust the the screen control (it is mounted on the flyback transformer) the one with the wire coming out the top and going to the picture tube
the lower one. it is black and serrated and less than 1/4" in diameter.
turn counter clockwise first then advance it while someone watches for the picture.
If it comes on you know the tube is weak.
it may last for a while at that setting, but be prepared to buy a new set.
Thanks Guy9
