SOURCE: toshiba 42wt29b. screen keeps turning blue

MMMM Hard call here. The fact that it does try to come on blue maybe an indication that the power supply regulator circuit is good. It could also be a shorted blue tube and when it comes on its overloading the screen drive and the set goes into overload protection shutdown. The real way to see Would be to pull off the blue crt socket as well as the Hi Voltage lead on the crt and see if the set comes on without blue. If it does Your gonna need a pict tube. If it dosent then troubleshooting along the switched power supplys would be neccassary.. BUT I advise you THAT IF YOU HAVE NO EXPERIENCE TROUBLESHOOTING TV SETS PLEASE SEEK A PRO TO ASSIST YOU AS THERES VERY HIGH VOLTAGE INSIDE THESE SETS EVEN IF THEY ARE UNPLUGGED. GOOD LUCK

SOURCE: Picture gone from TV Model LE46M51B

I suspect that your backlight has gone out. If you shine a light on the screen can you see remnants of the picture that should be displaying? If so, it's definitely the backlight, and most likely the power inverter for the backlight. You can probably find a replacement inverter, but you may need a repair manual to install it. I'd recommend checking the warranty status first and sending it in for repair if you can.

I cannot tune my goodmans gtvl19w17hd tv


If you have sound, then your tv doesn't need tuning. Shine a bright light onto the screen, can you see a very dim picture? If so, your backlight has stopped working. This is almost always due to the inverters failing and can be repaired.

Goodmans flat screen TV.Blank screen


If it is a LCD TV, and there is a faint picture, it is probably the backlight or inverter board (probably the latter). This is a common problem (especially with PC monitors).
Do an internet search for your model and inverter, you may be able to replace it.
Make SURE you REMOVE the power lead before opening the set !!!!
