Question about Mitsubishi WD62628 62" Projection HDTV
Our Mitsubishi wd-62628 has a random problem where the picture freezes and sound stops. There is no control at remote (can't change channels, etc). Then after 30 sec or so, the TV shuts itself off and the power/timer green LED blinks rapidly for 30-45 sec. Once that has stopped, the TV can be powered on again and works normally, as if nothing happened.
This may happen once a day, or once a week. It doesn't seem to have any preference of which TV channel it fails on (we only use over the air antenna signals). It has frozen/shut off while watching analog or digital channels. It may happen after an hour of use or after several hours of use. We first noticed the problem more than a year ago.
The TV is under an extended warranty. A local repair company contracted out by the extended warranty issuer came out a few months back and did a complete reset of the TV hoping that would take care of the issue. It did not. The same company just came out on Monday and replaced the E2P board (Mitsubishi part # 935d820001-v30, pwb-e2p v30). It had been 11 days since the last time the TV froze and shut off previous to them coming out. Now two days after the E2P board was replaced, it froze and shut off again.
The repair company is wanted to take the TV into their shop to try and reproduce the failure. But they haven't conveyed to me exactly what they plan on doing. I told them I am not allowing them to take the TV until they have discussed the problem with Mitsubishi and have determined EXACTLY what the next step will be.
Any help on what to tell them would be appreciated. I get the feeling they have no idea where to start, now that their two attempts to resolve the problem have failed. And as long as the TV works (at this point the problem is mostly a big annoyance), I am reluctant to let them have it, just for them to have it powered up in hopes it will fail for them. It could take WEEKS and the chances of them being there when it happens are slim.
Intermittent problems are the most difficult to find because they don't show up long enough to trace them down. Today the digital sets are all cpu controlled and a glitch from any board can lock up the set. The problem can even be software related, such as settings or firmware updates. Unfortunately we as technicians do not have a history of symptom/cause on the newer digital sets. Your best bet is to e-mail Mitsubishi with the symptom as described above, such as the blinks, E2P, signal source etc ... and ask them what they think. firstname.lastname@example.org good luck
