Hi - My Sony 32 inch Bravia TV regularly switches itself off then back on after approx 25 seconds, whether midway thru a programme or sometimes inbetween progs on the same channel
Or sometimes when I am changing channels. Would appreciate any advice - Many thanks.

There are no fans inside your 32 inch Bravia. I don't know the sound you are asking about. Is it a high pitch squeal? Is it a low volume humm? In either case you may hav e a bad filter capacitor or a problem in the Dolby noise reduction filter. In any of these cases, the filter cap in any location on the board can create the first sign of a problem. For starters, always suspect your filter caps.
Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/
In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
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"
If you bought it brand new from a dealer, I would take it back or have them come out and look at it. Less than a month old, it is still under the 1 year MFG warranty or the very best a 30 day one.
