Did you ever get your tv fixed? My tv wouldn't turn on this morning for the first time. It made a awful clicking noise. NO sound, or picture. I've only had my tv for 1 1/2 years.

TV does not turn on? (Relay problem?)


The power supply could be failing intermittently. That's why it sometimes works and sometimes doesn't. Also, the relay could be erratic.

Tv will not turn on and green light blinks 3 times constantly


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!

Toshiba Color TV Relay clicks slowly. TV does not come ON.


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,

Toshiba cf32c50 tv will not turn on


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.

Hello ****, I have the same problem. However. I manage to get the TV on by pulling the cable out and then plug it back in again several times. A couple of times just after you have heard the first click and the a couple of times just when you hear the second click. Sudenly the TV decided to work again. I think it must be a problem with one of the two relays that sits next to each other near the centre of the TV. If you take the back of and then plug the power back in you will see the two lights next to those relays come on and then die out when the relays let go. This is what hapens if the TV doesnt work. If the TV works those lights/LED's will stay green and the relays will hold on and feeding the TV screen. I will probably try to see if I can buy replacement relays and replace these. If I can get hold of them, then probably I would take the existing relays appart to see if I could see any fault. If those relays ar ok and the replacement relays appear in the same manor like the old ones I would look for problems before those relays. Maby order a new circut board from Samsung.

Ok. I got my tv back on.
I pulled off the back cover and found the relay that was clicking.
I have two blue relays next to each other that click when the power is pushed.
I placed a hair dryer over the relays for about a minute.
Once heated up, it only took 4 tries to get the TV to stay on.
