JK321 32" High Definition LCD TV no picture has vertical lines on left side of screen, is it worth fixing.


Hello,

well this is common on your model and could be a few different things. one is the video circuit and a cost would range around 100.00. the other is a weak picture tube this would cost more than the TV new. sometimes when it is the tube we can adjust it but it does not always last long. sounds to me it would be better to invest into a newer TV in this case.
good luck :)

We have a 32 in lcd dell tv with sound no picture...


Yes, either a new back light, or a new inverter (the circuit inside the TV that powers the back light): http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=120540641447&rvr_id=&crlp=1_263602_263622&UA=WVF%3F&GUID=a4a3861a1240a0aad0b022b0ffee21c3&itemid=120540641447&ff4=263602_263622

It looks like the parts for your TV are readily available online (unusual), but I couldn't find the backlight itself, sorry.

Will not come on, the lights come on but the screen is still black


This sounds like you have bad capacitors on the power supply board. Look for bulging capacitors. Any weak capacitors will have a bulge at the top. If you know how flourescent lighting works with a ballast, tv's work the same way to power up the backlights but use capacitors. The backlights when lit allows you to see the picture. If they are not charging up fully you get a black screen or a very dim screen which looks black under normal lighting conditions. Sometimes you can turn off all lights and maybe see a faint picture.

32 inch Samsung LCD TV has no picture


do this test, turn tv on and touch the screen if you can see light in the background it is the panel if no back light is present then it is the power board.
