Cannot get power to set. There is no reset visible on back of set. Is their an internal fuse or breaker that could be changed by taking the back of the set off?
Have been told by tv repair people the set is to old to mess with, and even if one could find parts it would be very expensive to repair. Until this problem, the set worked perfectly with excellent color and sound. Set is used very little usually during holidays by grandkids.

Re: Mitsubishi console TV Model CK2689R
Your tech could be correct... These were GREAT sets in their time and many are outlasting sets half their age.. When Mitsubishi announced in 1999 that they were discontinuing direct view manufacturing because they wouldn't compete in a throw-away market I was a bit sad as a technician because they were the cadilac of Tvs for how they were built. But alas everything does come to an end...
I would suggest checking the fuse at F901 for open. If it's open then it's likely C587 has failed and the horizontal output transistor. If F901 is intacted then you would need to do some trace testing with a scope to see past the smps what's happening to your power. You might try researching the NESDA site for a nesda technician near you. http://www.nesda.com/locator/state_search.php
Hope this helps!

If your power outage wad caused by a surge your tv may have died. Check fusebox for tripped circuit breaker also check tv wall plug fuse in case that has blown. It might be that the tv internal fuse has blown, you should disconnect the tvv from the electricity supply if you intend opening the rear of the set to check this.
If they are all okay the set probably needs the services of a trained technician
Hi,There are a number of reasons that might prevent a conventional (CRT) TV from turning on. If there is power to the set and it won't come on, there is an electronic problem. There are start up circuits inside the set, and they essentially form a "loop" of sorts. Any "break" in the loop, that is, any failed component in the loop, will prevent the set from starting up.
Some sets have an internal fuse, but very few actually do. Protection is provided by components other than a fuse, and the failure of any one of them will "kill" the set. It should be noted that some components in the set fail because others have failed. The failure of multiple components is possible because of the design of the set.
It could just be the relay that turns the set on when the remote or main power button is press.
Some sets have a circuit breaker on the back that my have tripped. May look like a little red button that you press to reset. Some set have a internal fuse. This fuse is something that needs to be replaced by a professional. If it has a breaker on the back and you set it and it works, no problem. If you reset it and it trips again, have a pro look at your set.
The TV probably has an internal short, most likely in the power supply. If you open it, you will probably find the main fuse is blown (which is why it didn't trip the breaker again. Don't bother replacing the fuse until you find and fix the short - you'll just blow the new fuse and probably trip the breaker again.
The only possible check that could be done without removing/opening the Audiovox TV would be to check for the presence/absence of supply power/voltage depending on how the TV is powered (12VDC or 120 VAC). Normally, there would be an fuse and/or circuit breakers.for the RV's entertainment system including the TV.
The 120-volt circuit breakers and 12-volt
fuses are located in the same compartment. These devices interrupt the power if
the circuit is overloaded.The 120-volt circuit breakers include a 30
amp main breaker and several smaller breakers for individual circuits. If a
circuit breaker is tripped, look for an overload on the circuit, then reset it
by turning the breaker OFF and then turning it ON. Do not try to reset a breaker
the second time without locating the overload problem. The 12-volt fuses protect
individual circuits. If the circuit is overloaded, it will blow the fuse and the
fuse must be replaced. Check the circuit for an overload and replace the fuse
with the same type or amperage rating.
If the above checks out, then problem is internal to the unit and would require removal from its current position.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Since you have a lit power light, you are getting AC power.
Your set either has a blown internal fuse (or circuit breaker) or a power supply problem. If you can reset its breaker or replace its fuse, you may be able to fix it yourself. If not you need professional service.
