which electronics board to replace in LCD? (gray vertical lines)
My parents' 8 years PILOT 37" LCD TV displays thick vertical gray scale lines.
It happened 3 weeks ago, suddenly, the picture became gray, the sound kept on for a while and then disappeared.
Exact model : PIL3700CH (pic 3)
1. When I connect it to the electricity - the red led outside of the tv is on.
2. When I turn it on (using the remote control or the on button) - the green led outside the TV is on.
then, the screen display is all gray (pic 1), and then it stables at these thick vertical gray lines (pic 2).

3. when I opened the back cover - I did not notice any blown capacitor, nothing seems or smells burnt.
4. I have googled a lot, and now I assume that the fastest solution will be replacing one of the electronic boards (T-con / main / power / inverter ).
but I don't know to relate the symptoms to the right board failure.
Does anybody know this issue and can advice please ?
Is this a good question?
