When I turn on my 42" LG LCD tv the screen remains blue, yet I watched it this morning. What is wrong how can I repair it.
Make: LGModel: 42LB1DR
Messing with all the buttons, turning off the mega big surge protector. Short of putting my fist through it.
Do you see the on screen indicators, volume up , channel number etc?
Do you have other tv's in the house connected to same cable , antenna, sattelite?
What are you using Sat, cable , off air antenna?
Will a dvd playback?
Nothing appears on the screen - it is completely blue, no channel, volume or any indicator.
Yes our other tvs work fine.
We use comcast cable.
No a DVD will not play on the screen
Plus it seems like it takes a really long time for the tv to turn on and off.
Thanks for the additional info.
This is a fairly technical repair that would require unsoldering capacitors and installing
My records show that there have been many failures of C235 2200@10V capacitors in the power supply.
Some symptoms include backlight only (blue screen) or Intermittent picture and sound. No menu operation , slow power on & off. Replaced 2200uf 10v caps on Main power Supply board. check for bulges in these capacitors.
check these capacitors as well CAPS C235, C201, C218, C219 .

So is this something a tv repair person can do and is it an expensive fix or one that should be done - rather than purchasing a new tv?
It is something an experienced TV repair person could do.
I would think a fair cost to repair should be in the $150.00 to 175.00 range.
Parts cost would be 20 to 30 dollars, the rest labor.
