Question about Hitachi 42HDM12 42 in. Plasma Television
New plasma tv only 5 months old. When turning it on, it makes a buzzing sound a has vertical lines going across the screen. Doesn't recognize Direct TV box in input 1 or DVD player in input 2. All is plugged in properly. What could have happened all of a sudden??
First of all check your connecting wires see if they are not broken inside.or try some new wires.if that does not solve your problem then you have to start looking at the tv as defective,therefore,it ca be either of these problems 1 defective tuner associated with vertical problem. 2 faulty IF-AGC section solution ajdust IF-AGC verify active components leaking,open,or shorted IF transistor or IC REPLACE either.one more thing give it some slight tap on the case if it resume operation you have lose solder then the circuit needs to resolder.if it remains the same considering the above take it to a tech.good luck.
