Check Regulator for 132V +-. Check for 32kv at CRT anode. Try lowering screen control on the flyback.

Sylvania TV - 3 tics


Not economically. The ticking sound is a sure sign of high-voltage shutdown, and is coming from your flyback transformer - the most expensive part in the TV besides the picture tube. Even if it's not the flyback, troubleshooting the high voltage section is usually more than the cost of a new TV.

Shows for one minute then goes tick, tick and shuts off


ok try this , unplug the front control board , if it stays on then thats the problem , but if it don't , then you will need to check the components around the EEPROM and resolder all components that heat up, it is possible that the crystal and EEPROM may need to be replaced but doing these other things plus a couple of more checks will help find the culprit
also make sure all work is good, resolder and recheck are the best way to eliminate any problems
please give a fixya rating so that i may continue to help you if needed , thanks

My TV


the old ticking sound... yes.. it means your power supply shut down and continously trys to reboot ... hense the tick sound as the voltage rises and fails.

Means you got a short somewhere. Most likely the obvious high power consuming High Voltage Suppy... and as I found in 99.9 percent the Horizontal power Transistor shorted... 80 percent Flyback, 10 percent audio... 10 percent some odd circuits like vertical or yoke as shorted.

you have a short.

It won't turn on


The smell of something burning is not a good sign. The clicking sound you are hearing could be a relay or breaker kicking in and out as a result of whatever is wrong.

This could be cause by:
1. A problem in the power supply.
2. A problem with the Horizontal Output Stage.
3. The Flyback transformer.

Someone gave me a TV once that had the same problem. I determined that it had a bad flyback transformer. I replaced the transformer and the TV worked about 5 secs before I saw some black smoke come out of the new flyback. I turned it off right away and realized that something else was bad that caused the original flyback to burn up. The same thing was causing the new flyback to go as well. It turned out to be a shorted, 50 cent hi-speed switching diode. Fortunately, because I had turned the set off quickly when the 2nd flyback started to smoke, once I replaced the diode, the TV was fixed.

If you want to get it working again, you'll need to have it serviced.

Good luck,

TV making ticking sound when turned on


most times I hear that ticking its the high voltage failure ...most likely a shorted HOT fallowed by flyback. the ticking is your shut-down engaged.

TV TURNS OFF AT DIFFERENT INTERVALS


How old is your TV?
TV's have a circuit that monitors the high voltage and shuts down the set if it senses something amiss. If the set is at least 10 years old this is typical and not worth repairing. If less, figure on replacing the flyback transformer.
Hope ya fix it!

TV starts but Does Not show picture or no sound


The Tic Tic sound is a result of the high voltage shutdown circuit. Thats what the circuit does if theres a short in the Highvoltage sweep. like maybe a shorted horizontal output transistor??. The only way to really tell is go in and measure the start up voltage and if the Hivoltage comes up and shuts down its a fault in the shutdown or Hhv regulation circuit . if it dosent come up at all then the faults in the Horizontal sweep circuit . Hope this explains a bit? good luck
