Ken, If you give us the model numbers then we will be in a position to help you regarding bad reports. The top 4 manufacturers currently (LG, Panasonic, Samsung and Sony) make a wide range of models and in the main the majority of models attract favourable reviews with just the odd lemon.
Looking at Which? 32 inch TVs there aren't any Sony Best Buys (and yes I know some FMs don't rate Which? reviews but the OP might). Apart from the Samsung Best Buy I mentioned in my post above, the LG 32LS570T gets 67% and is the third rated Best Buy for 32 inch TVs. The two top models are both Samsung but considerably more expensive than the LG, and only 1 and 2% better in terms of picture quality.
The 2 Best Buys below the LG above are also LG; the LG 32LM620T at 65% but more expensive than the 570T, although Which? reckon the sound is better, and the LG 32LM3400 also at 65%, but this TV is not Full HD and does not have a Freeview HD tuner.
You totally fooled me with your opening post as I thought it was a new TV, rather than a fault with an old TV. I reckon other FMs thought so too. Perhaps if you start a thread in the future about something similar you could mention this point to save people wasting time. It would be nice if you could thank FMs for their help too. mac2708 went to a lot of trouble looking in the manual for you.
