When I turn on the unit, all it does is makes a clicking/ticking noise...nothing else happens...i have a magnavox mpd845 portable dvd player

okay that clicking is from the relay switch..its just because either the micro chip,regulator horizontal output..or some other component in the power supply is not your tv cant come on that is the reason you are hearing the clicking need to take your tv to a tech so that it can be repaired.good luck.

When powered on the tv makes a constant clicking sound

THe clicking noise is the relay on the PSB that allows AC to be sent to the psb. It won't hold in due to some fault either in a resetable link or some other safety component. To check this unplug the cord from the mains for an hour, then try again. You should hear the relay click once and then the TV will power on for a short period before powering off again. The solution is to replace the component, other than that replace the psb. I can't get a manual to prove this so I am just making an intelligent guess until I can prove it.

Power light comes on,clicks before picture comes on then shuts of

Yes, it is either that or the "Startup Circuit" is faulty usually it is the associated relay. Thats the clicking sound you hear. When you turn on the TV, the relay is activated along with a timing transistor, the Relay has to make contact within a certain time frame. If the contact is not made during that time frame, the TV shuts down. This is a safety feature in all TV's. If you can get a schematic it will show you where the relay is or, after you unplug the TV and wait 15 minutes, you can take a look inside at the main circuit board, sometimes they mark the area with either "START UP" or "SHUT DOWN" and there you should see a relay.
But a new one usually has to be soldered in.

Should have been 3300 UF 10V caps that were bad? Shouls have been replaced with 3300UF 18V. 50V is huge. If it was replaced with a 50 the polarity may be wrong or the cap it too big to be seated property. Sometimes the caps just dry out and even a normal looking one will be the culprit of no OSD. Are you getting an LED fault code blinking? That should be a red led. Do you hear the relay clicking.? When you replaced the caps did you charge them? Just plugging in the set without trying to power it on for about 20-30 mins. I may be able to help you

Hyundai plasma model HP-4200

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.
