Green and purple vertical stripes on our TV screen

Our TV was working perfectly for 3 years, but now when we switch it on, the picture comes on for about a minute, and then the screen becomes mostly green and purple and covered in vertical lines. Sound still works fine. Very grateful for any ideas of what might cause this! Model is a Toshiba 32ZP38B

    I have a samsung lcd 42 inch tv which is 18 months old. Over the last few weeks, the picture suddenly turns a purple/green hue. It sometimes lasts for hours and then pops back to a normal clour. It has now been purple/green for the last two days. I have tried to reset it to factory colours with no improvement, I would appreciate any suggestions or repair solutions.



    Many Thanks Darlene

The cause is one or more shorted transistors either on CRT board or on main or both. The colors are red,blue and green, you have a transistor for each and a bias trans. check each there are 6 in all.

It will be best to contact the authorized service center for Samsung in this case. They only can provide the component.

Vizio TV has purple haze and colored stripes on the sides of the picture.


You possibly have a failing hi-voltage module or fly-back transformer going bad. If it has a fly-back transformer, It's not worth the trouble. Some repair shops will sell you a module. Call a repair shop for help.

Green and purple horizontal lines


You will most likely need what is called a scan converter/scaler. It will convert your source signal to the desired signal for you. You can find these online.

Green vertical bars on a Samsung projection


That is a problem with your main board - some of your inputs work fine and another is bogus. The tv input is not working because there could be a defect in your tuner. If you have cable try a different input for the signal.from the box. If you are using OTA, then use an external HD OTA tuner to feed your set.

Thank you!!!! Our power was off due to new transformers being installed in the area and we had no clue how to fix this. I called around and no one seemed to know the answer (not even Samsung, who only wanted to tell me my TWO year old tv was out of warranty),so I tried this and it worked perfectly!!! You saved me a bundle! Thanks!

2-inch picture stripe in middle of screen.


deight, your set is going into total vertical collapse, either the vertical IC is failing or some support component to the vertical circuit is failing, should not be an expensive repair, hope this helps, BMW Rider

Samsung TXN3275HF 32" tv - purple picture


Chuck the TV - probably It depends on the repair facilities available where you live. In big urban areas the cost of staffing a repair shop is such it can cost nearly as much per hour just to look at an item is it does to buy the next one-plus you get all the latest features.
