Insignia tv sound but no picture

At 8 years age components are wearing out. It sounds like a power supply issue. It is not cost effective to repair.

I have a proview lcd screen and it palys the tv shows in back ground but it's a dark screen like dark blue no picture. Volume and everything working but just no picture. What can i do.

Show a torch light on the screen for a distance, and if you can see the picture, the backlight is not lighting up. Check for its settings on the remote, if you have that option. Check also the settings of brightness/contrast/sharpness/color. If you still have problems, please call in a qualified service technician.

When I turn on my tv it may at times have a white screen-then it goes dark and eventually the picture will come back, its been happening more and more lately.

The lamp only has a life span of about 8000 hours if you are past that then it maybe time to replace. If you average out 6 to 8 hours a day X 365 x years you will get the average hours used, not sure how old you set is but the formula works.

Dark Picture

The procedure for correcting dark picture is EXTREMELY dangerous.. If you're not sure about what you're doing call a qualified technician or you could seriously hurt yourself or get killed!

Picture Dark, abnormal, Changing Color Temperature
  • Clean the Spark Gaps on each CRT PWB. Remove the Cap, clean the contacts with thin fine sand paper, blow out, reseal.
  • Remove the CRT Sockets, clean the pins on the CRT. Push the CRT socket on and off several times.
Make really sure before you sttart this process that the Tv has been unplugged for several hours and that you discharge the crt as you remove the anode. There is some extremely high voltage present for hours after the Tv has been off...
Or get a reputable shop to come out and do the procedure for you - - might just save picking yourself up of the opposite wall.
