Model number: hPS553 X/XAA. Yes have turned power off to both and does not help
I have this TV for 6 years, but its is only used during the winter months (6) every year. And just returned and it only worked for two days, the problem started two days ago.
It is a satitlle box and have another TV hooked up to it also through the box and this TV works OK The menu screen shows up but is in black and white and with the lines and bars etc. and some times the TV does not come on at all, except for the sound. so no menu..
Thx for your help, and this information I already had (about the capacitors), but thought it could be fixed without a tech. You only confirmed what I already knew. But thanks anyway.
