Question about Hitachi 42HDS69 42 in. Plasma Television
My tv is 1 year 3 months old. Its never been moved, touched, bumped or anything. Yesterday it suddenly went off. Now it won't go back on. The red standby light stays on, but nothing else. If I hold down the power button on the side for like 10 seconds, it clicks and sounds like it will start up, but nothing.... Then then blue "on" light comes on, but thats it. If I push power again, back to the red light. I tried unplugging it (overnight) and same thing. When I first turn the main power switch back on after unplugging it buzzes and sounds like its powering up for like 20 seconds, but nothing. I paid $1,800 for this TV and warranty expired 3 months ago... I'll be really choked if its dead. Any advice?
Hi, everyone. Me too have the same problem. TV just stays in red but won't turn to blue. I tried unplugging then wait and restart again, sometimes it will work but lately that trick doesn't work anymore. Then somebody suggested to open the back of the tv (it's not hard... just a lot of screws and a couple of bolts to remove) and clean (vacuum) the exhaust fan. Out of frustration, I did open the back and clean the the fan (has a lot of dust on the blades) and everywhere where there is dust. Just be careful not to touch any part of the printed circuit board with the vacuum nozzle to eliminate the destructive effect of static electricity. Or while you're cleaning it you have to hold the metal frame with your other hand to ground yourself (by the way you have to unplug your tv before you start opening the back). After the cleaning then covering the back, the tv worked... for only a few hours. It did stop working again as soon as I turned it off then on again. Again I opened the back, this time I removed the power supply board ( that's the biggest board and located above where you connect all your wirings). Got myselt a small brush and start brushing and vacuuming the dust out. I don't know if the cleaning did the trick or it was the unplugging of the connectors from the power supply board. All these work did the job... my tv is still working for almost three weeks now. Another thing, when you have a a time warner cable with a dvr box where you can program its remote to power most of your equipment in sequence by pressing the remote power button, I set it so that the tv will be powered up last considering that power can fluctuate everytime a unit starts up specially when they are all connected to the same power/surge protector... tv doesn't like it when the power fluctuates while it is still starting. Hope these helps.... (Hitachi 42HDS69)
