Hitachi 42DP9700 – High pitched hum/squeak

oops

Standard Member
I brought a Hitachi 42DP9700 Plasma TV in May this year. Recently during the hot weather I have noticed after approx 20 to 30 minutes of continuous usage the unit develops, want can be best described as a high pitched hiss/squeaking sound. I just wanted to know if any body else has experienced this sound? A friend told me it could that step down transformer within the unit. Can any one throw some light on this issue?

It could be the power supply.

If you look on the 42PD9700 owners thread, a few of them have had a buzzing noise, which seems to be fixed by calling Hitachi, and getting an engineer out to replace the power supply. worked in most cases.

Or if its only a few days old, possibly get another unit from the shop
