Re: Picture turned pink
This all of the sudden happened if so you may have lost the green alot of times yoiu can fix the CRT drive Brd there is a video amp ic and a resistor that can be replaced or yo can replace the whole Brd a little harder to do than just replacing the parts on the Brd

Examine the screen with set on and color set to zero--stand back and look= is screen pink to red color?
If so it may be a common issue on this Hitachi.
Usually it is an adjustment inside the set of the red screen control needing to be turned just slightly down---these are known for the red control "drifting" just slightly from time to time--answer is based on model number indicated here.
If before it was going rather bright red or a version of that--it is related to the circuit for the red picture tube this set uses---the tube itself or the circuit board that plugs onto the end of that tube.
If bright red, green or blue screen set will detect too much current being drawn and blank or turn tubes off; not likely a do it yourself repair and this set is prone to this and many other problems---Just Google the model number with "problems" and see what I mean.
I will assume from you description that this is a rear projection crt(picture tube) tv. if this is true I have good news/bad news.
faint red horizontal bowed lines in the picture indicate the screen(G2) voltage for the red tube is too high.Slight lowering of the G2 adjustment will eliminate these lines. I stress SLIGHT because too much adjustment will mess up the gray scale .
The bad news the red crt made be bad. if the adjustment works but in the future the problem reappears then suspect the red crt.red crt replacement is probably not economical to repair.
yes it could ba the cable itself even, but i suspect more the tuner circuit or tuner itself may have bad solder connections. Here is another test for you to try, plug another dvd or vcr, or xbox etc. into the back, using one odf the inputs. See if this works like the built in dvd. if so it will be more likely bad connections in the tuner or surrounding circuit.
