Hyundai plasma model HP-4200

Hi there i have a hyundai plasma tv the problem is it wont turn on when you switch it on you can hear a relay click like most tvs and you can hear it tring to come on then you hear 2 more clicks from relays then nothing, on the rare occasion the tv will turn on and when it does you dont get the 2 more clicks, i have been looking at lots of other sites with no joy as i think i could fix my self as i have had the back off and most is big circuit boards that just unplug but dont no what to change .
any help would be most greatful.

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.

2001 hyundai elantra-winshield wipers not working and it is not the fuse under the dash. could it be the fuse relay under the hood?


It could definately be the wiper relay, and it could also be the wiper motor. If you put a long screw driver on the relay and have someone turn the wipers on with the key on, you should be able to hear the relay clicking as it opens and closes. Sometimes you can put your finger on the relay and feel the relay switching. If you can hear/feel the relay then the next step is the wiper motor. Hope this helps.

Hi I have a LG 42' plasma, but it wont turn


Hi Paul, This seems to be a common issue in most of the plasma flat screens. You are almost accurate in guessing the reason of trouble. The issue with the TV is mainly with the power board itself which happens in most models. Even though if you try replacing board level components you will finally end up in replacing the power board for sure. I managed to find a contact who can help with spare parts of most of the plasma models...i am posting it here for your reference. plasma TV parts-- Steve Hu: masterhu@yahoo.com .
Have a nice day!!!!
