Check the speaker/s first. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis.

Hello brattbabie1,

Ok you have sound and no picture. This denotes that since this is a plasma TV the circuitry that controls the activation of the screen may have become defective. You will need the schematic to show the voltage levels that need to be present on the cable that connects between the screen and the control circuit and a voltmeter to measure those voltages. I would suggest that you get a qualified TV technician to work on this problem, due to the technical nature of this issue.

I hope this helps,

Thank you,

SOURCE: no picture -- white screen -- no sound

With no video and the the colored stripes, it sounds like the LVDS cable needs to be reconnected to the LCD control board or the control board itself is bad. If the unit is only 3-4 months old, it should be covered by warranty

SOURCE: sony kdl-40v5100 has handshake problem

1.This issue sounds as though the TV connection circuit has an issue.
2. You have changed the DVR and the HDMI cables and you still have an issue with the video (pink screen) indicates a video circuit issue ( improper voltage or current) at the video section of the circuit.
3. This will require some troubleshooting by a qualified tech.
4. To make sure, try connecting another properly working LCD TV to the cable box or DVR an check.If you get a picture and sound properly it is the TV.
5. Usually a cable box is QA'd (quality assured) by the company and will not be sent unless tested 1st

I have a black screen. Cable company says I have


This is a common problem with Cable companies when they update their firmware. This makes the two incompatible. You can try going onto www.samsung.com and look for firmware updates for your model. Follow the instructions provided. If this does not work then you have a bad cable box. Cables companies are notorious for blaming the tv. Don't let them fool you. Stand your ground and insist on them correcting the problem.

NO Picture or Sound


sounds like someone rolled over on the remote. if you have cable or a dish, the tv channel must be left on a specific station at all times. no matter what channel is on the cable, the television itself must be on the correct channel number in order to receive he signal from the cable company. try hitting the last channel recall button on the tv, not the cable. otherwise try channel 3 or 4 or sometimes 60 on the tv. good luck
