Sony bravia 40 brightness control not working

SOURCE: Sony Bravia 40" LCD TV generating heat.

First, you will have to define what you mean by "hot to touch" ie.:
can you or can you not hold your hand on it for a few moments.

Hi,

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"

Thanks

That actually happened to a tv of mine once-i had some clear diet soda get spilled on front, I didn't clean it out(just off of screen) and I corroded the contacts on the lcd itself. if it is a recent problem get it cleaned/clean it yourself as soon as possible to prevent damage to screens connections. hope this was helpful, good luck.
