Toshiba Color TV Relay clicks slowly. TV does not come ON.
I have a Toshiba Color TV mod: 20AF41C. When I plug it in, the relay ''RY501'' clicks about once every 4 seconds. When it clicks, the contacts inside the relay do not stay closed. The coil is not energised enough to close the contacts. Only enough to cause the clicking noise. I have opened the relay to confirm that this is what happens. I also removed the relay (RY501) and if I connect the set, I hear a very faint click at the same speed (about one click every 4 seconds) I tried to discover the source of this faint clicking, but it is too faint for me to locate where it is coming from. If I press the power switch, nothing happens. I tested the Power switch, and it is normally opened, and it closes when I press it.

Re: Toshiba Color TV Relay clicks slowly. TV does not...
Electrolitic Capasitors in the power supply going or being bad will cause this. At some point a low value resister also will start to run hot or burn up. I believe it it a 16v 1500 uf cap near the relay. I would also replace any 10uf 160v caps in the powersupply too.
Hope this Helps,

Hi, First check that you have good power coming in from plug. If that is good check out power board (capacitors Bad) replace if oozing out or bulging out. If you are good with soldering then do so.
Replace with same capacitors or better ones.
It wouldn't be your output transistors. If they go bad they blow the fuse. Sounds like a speaker relay problem. Have you checked the solder connections on the relays? They sometimes break down. If that doesn't help, I would replace the relay. Center channel goes through RY501. Sony p/n: 1-755-170-11.
Your main power board located in the center where your power cord will plug into is going bad, actually it's just a relay. I have the same problem, tv works for hours til relay overheats, then tv shuts off and tries to restart, hence the clicking and the 3 green flashes, mine will actually restart after 15-30 minutes. search online for the board, ranges anywhere from 150-280. I haven't found anyone to sell just the relay. I am trying tv with rear panel removed and cover removed from relay to see if relay will not malfunction? Board is a simple plug and play, just remember to have the tv unplugged.... you can actually remove the rear panel while on it's stand, just don't remove the screws holding the base onto the tv. Good luck!
I HAVE THE SAME PROBLEM ,I FOUND OUT AFTER OBSERVING FOR QUITE SOMETIME THAT THE CLICKING NOISE I HERE AFTER PLUGGING IT TO THE OUTLET CAME FROM A RELAY SWITCH LOCATED ON THE POWER BOARD AFTER TAPPING ON IT THE SET WOULD POWER AND THE BLINKING RED LIGHT GOES TO NORMAL..I BELIEVE THIS RELAY IS CAUSING THIS PROBLEM FOR ALL THE FELLOWS OUT THERE WITH THIS TV SET AND THE BLINKING RED LIGHT..IN MY CASE THE RELAY WENT SO BAD NOW THAT THE COIL THAT MAGNETIZES TO CLOSE THE CIRCUIT GAVE UP ,SO I PULLED THE COVER OF THE RELAY TO UNVEIL THE TWO METAL STRPS THAT COME IN CONTACT AND HAVE BENT ONE SLITELY TO REMANE CLOSE THIS POWERS THE TV UP NORMAL BUT IN ORDER TO SHUT IT DOWN I HAVE TO PULL THE OUTLET. THIS IS TEMPORARY UNTIL I CAN FIND WHERE TO GET RELAY SWITCH. PLEASE DONT TAKE MY RESEARCH AS A SOLUTION BUT FOR WHAT EVER ITS WORTH. I WILL GET THIS UP AND RUNNING AGAIN ITS ALL WORTH EVERY DOLLAR TO FIX.
This is a typical condition if the power supply has failed or a power-consuming circuit the supply services has exceeded a predetermined current draw. The relay you hear is preventing further damage or even fire. You will need local tech help with this.
