SOURCE: Samsung HDMI issue

Have you try to replace your HDMI cable?I recommend you to pick up a good Monster HD700 HDMI cable from a local retail store like best buy or circuit city.In case it isn't the cable problem,you could return it.
However,when you are a using the HDMI cable,it is normally either have both picture and sound or nothing at all.Are you sure you didn't hook up the audio OUTPUT from your TV back to a receiver input?
Or even an optical output from the TV to the receiver?

SOURCE: Samsung 50" plasma won't turn on

My 42" plasma is making a clicking sound, then it switches off and keeps clicking but not switching back on, when it does go back on it stays on for just a few moments, it is only 14months old.

SOURCE: Have sound but no picture on Samsung plasma

It's a pretty common problem. The no picture but sound problem is usually the y sustain board. I've replaced 2 on mine now. The 680uf 35V capacitors usually are bulging because one of the power transistors went and took them out. This has happened to both of the y boards I had. One time the failing y board took out the buffer boards too, and once it did not. The fix is super simple and anyone with even the most rudimentary knowledge of computers or electronics can do the labor yourself. You should do the simple stuff first by just doing a quick test with a multimeter. Just check the power coming to the y board. After that you can just remove the y board by removing 3 cables and like 3 screws. Plug in the new board and it's done! You can source the parts from a place like shopjimmy or discount merchant. 3 boards were like 200 bucks. 1 board is like 100 bucks. Labor took me 15min. Think about that the next time an electronics repair place charges you 1000 dollars. Of course they check everything (Yeah right) and warranty their work (I don't) but if you check the service manual it states that this is the most common repair. Look for the Canadian manual online. Hope this helps!

It's not the x main. 90% of the time it's a y buffer that goes out. It's usually the top buffer. 3/4 of the time the buffer takes out the y main board too. You cannot just replace the y-main or buffer because it will just burn out the other within seconds. Also about 1/4 of the time it'll take out the top transformer on the power supply too. The solution? First disconnect the power to the y main board. turn on the television and check the voltages coming off of it. Careful it's high voltage 208V! Remember it's DC too. Then disconnect the buffers from the y main board. You can try powering the y-main up to see if the little LED lights up. This does not indicate it's working though but it'll tell you if it is possible to fix. The fixes for these boards is only for electronics guys. It usually involves replacing 1-3 capacitors and 1-4 FET's. Since a bad buffer can take out a good y main in seconds it's usually recommended that one replace all 3 boards at the same time. It's a $250 fix. How do I know all this? I've now repaired 5 of these televisions. I owned one and spent close to 600 repairing it. I bought misc parts and broken sets online for months before I had 2 different repair guys walk me through the process of repairing them. I had so much cash tied up in parts that I bought 3 more dead sets and repaired them to justify all my spending. I've never had an x board fail. I've had EVERY top buffer fail. I've had all but 1 y-mains fail. and 1 lower buffer fail. I've also had the y buffer fry it's top chip, blow a capacitor and FET on the y-main, and fry the top transformer on the power supply before my eyes. It only took 5 seconds. Replacement of the 3 y boards will almost always fix the sound but no picture problem. Hope this helps!

Hi Its means that your television have no power.Maybe the power supply is dead.Its better to repair the power supply.If you have knowledge in TV,will you remove the back cover and check the power supply.Check the fuse if blown and check if the capacitors is leaked.

If the sound is still going and you can change the channels then the problem is most certainly the ysus or zsus board.

I have found the most common problems with the symptom you have described, to be the SMPS PCB. Sometimes the Y Main will cause the power supply to short out and lower a voltage in that area. Your set has a two year warranty. Call 1-800-Samsung to find an authorized servicer in your area.
