Question about Sony Bravia KDL-32V4000 32 in. LCD TV
Sony bravia LCD KDL52 TV: starts to show vertical color bands with soft edges after about 45 minutes of being in-use. On power-recycle and TV cool-off, problem gets corrected for about 45 mins.
It is most likely the TCON board (located at the top right against the LCD panel). When these boards have problems, they can act up when cold or warmed up.
You will want to check with any extended warranty company you might have, or Sony's part website for the availability of the TCON board.
The problem here is, sometimes those TCONs are not made available separately and need to be replaced with the screen.
If you have to replace the panel, buy a new tv. You'll save yourself a costly repair.

It could be 1 of 4 things:
1. One of the ribbon cables has worked itself loose (Simple Fix)
2. One of the assembly boards maybe faulty
3. The driver board which feeds the panel maybe faulty
4. The panel is faulty
The driver board in the UK costs approx £70 and approx £35-70 to fit it if this is the fault.
All other parts are between £80-160 and approx £35-70 to fit it if this is the fault.
The panel will cost approx 50-75% of what the TV was worth when you bought it - "Repair versus Replacement"

I had one vertical line it cam and went for awhile then stayed permanently and I took it in for repair only to be told they couldn't fix it now they are trying to give me a used tv (warranty don't want to pay) but I refuse I purchased it new and I told them I want a new one. I had that tv less than 2 years. So if you have a warranty and lines get it in fast.

You may ahev failing T-CON board, try having a small fan blowing at the vent on the back of the TV. If you can post pictures it will help a lot.
