I have a VISIO VW26L TV, when I power it on.. the screen is light gray.. gradually ask it warms it turns to blue.. then after a while longer.. the screen is perfect.. and can watch all channels no problem. If I turn the TV off and then back on.. NO problem as long as the TV is still warm... wait too long.. and the TV takes time to warm up again.

I replaced the back light inverter.. and it worked great. After a couple weeks, the same problem. I got another inverter (exchanged, because I thought it was bad again), installed new inverter.. no help.. still needs time to warm up.

Two options at this point.
The new (replacement) inverter is also bad.. or
There is a different problem.

Any ideas?
Thank you

Same problem.. same TV.. it's the T-con board (v260b1-l01 or C01 either one will work) around $35.. pretty easy to install. Then sell those inverter boards to get your money back.. lol
