    will all the fuses look like the one by the cord or are they a different style. Because i seen on the middle of the circut board where it said attention fuse but i didnt see a fuse. Should i look on the bottom of the circut board to see if there is burnt soder or will there not be something like that.

  • bkindle Jun 12, 2008

    i see on the circut board where it says "see fuse notice" but all the resistores around it have strips on them. I see things around them that set high off the board that look like resistors and dont have a srip but the have long legs. How would i test them to know if they were bad.

There is usually about 3 fuses in mitsubishis many models have more than 3. Look the bord over good where the power enters especially in the center of the board.

    There are some pico fuses that are either green, yellow or brown solid color that look like resistors except no bands they will be solid color green brown or yellow

    you have to unsolder one side and lift that side out of circuit to test them for resistance or continuity

Our electricity went out for a few minutes, and since then the TV will not turn on. The green light is flashing. We tried resetting it by pushing a pen point into the reset hole, but it does nothing. ...


Your power outage may have been caused by a nearby lightning strike, or any number of
1000 different reasons that cause power surges, brown-outs, voltage spikes, inductive loading,
and/or utility pole breaker trips and resets (this accounts for your power loss (a pole breaker trip),
followed by restoration of power (the pole breaker automatically reset) - even plain old high electrical demand causing an overload due to air conditioning demands caused by hot weather.
When the pole breaker reset, your TV caught a power surge.
Whenever a power outage occurs, quickly power off (or better, unplug) any/all computers, TVs,
etc. that are not protected by surge-protection.
As an electrician, when someone loses an item of electronics concommitant to an electrical
anomaly, its almost
always traceable to a nearby lightning strike (or the power company provided equivalent), accompanied by inadequate surge protection for
the VCR/TV/Computer/Stereo/uninsured valuable electronic item/XBOX 360/Nintendo Wii.
Surge protection can
be provided by the consumer at the power strip (a good one with builtin MOV protection and a
warranty costs $20, whereas a zero-protection 4-outlet or 6-outlet power strip will cost $4-$5).
Your electrician can provide whole-house surge protection where a whole-house MOV-based (metal oxide varistor) surge protector, or per-circuit protection can be installed with
a GFCI breaker (or better, an AFCI breaker) can be installed.
GFCI = ground fault circuit interruptor
AFCI = Arc fault circuit interruptor
Lightning protection is especially important in Florida, which is the "lightning capital of the world."
I've never found a good solution to lightning-fried electronics (random power supply components are destroyed and/or fuse blown), other than renters insurance or homeowners insurance.

Your only real hope for an economical fix is to look for a blown fuse, and replace it.

If desperate to attempt a fix on your own, you could try replacing the entire TV power supply as a module, but even this provides
no guarantee of a fix - lightning damage can extend beyond the power supply.
When traveling, I will always unplug everything before I leave (except the security system),
and also turn off the breakers to unneeded house circuits (which kills the wall switches that
control interior lighting - forcing a burglar to use their flashlight instead of interior lighting)
which is the least convenient lightning protection, but highly effective, and cheap (free).

I have a toshiba tz50v51 projection tv. the red power light is on


It could either be due to the convergence Circuits ( If the Power Indicator Blinks) or the power deflection board if it doesnt blink. I have a source for parts if you would like the link.

Lightning strike


This model is famous for capacitors being bad in the low voltage regulators on the signal board. Also has been known for cold solder connections in the power supply to the convergence IC. I don't have my notes at home but I belive that model only uses one IC for convergence, STK393-570. You cant see it from the back because of it being hidden by its heat sink.

Someone please help


Good Day;

Two things normally happens after a L storm:1.) One must unplug TV for 5 minutes, then plug back in. 2.) Main glass fuse out, will be near a/c cord. 3.( Power regulator IC may be out. Try these first.

Good Luck!

Lightning strike


Hello bkindle.....not a boat anchor YET!!!! Had similar problem with WS-55513 and it turned out to be a faulty DM board. There are 4 capacitors on the board that may have blown. If yo can solder, it is a pretty easy repair. I purchased a PDF manual for mine online to get familiar with the model.

Otherwise, you can expect to pay between 275.00 for a repaired board OR between 350.00 and 450.00 for a replacement board from Sears or Mitsubishi.

Hope this helps. I know it is frustrating but be patient.

Good Luck - Richard (MetalDad)

LIGHTENING STRIKE


Ed,
Open the back and take a look at the saw tooth filter cap. It's the largest cap you'll encounter in the PS. Just follow the electrical cord onto the board and look for a VERY large electrolytic cap in that area. Usually they bow at the top on a strike like that. Replacing the cap might restore the unit.
If not do you have an esr meter?

My vcr won't tearn on and its connected to my tv who now can not tearn on and on top of all that in my vcr there is a vhs that I need to return immediatly.


Hi,

Even if the TV is connected to the VCR, chances are that it would only be the signal (RF or Audio/Video) cables and not the power cords. Both not powering on would indicate an electrical problem such as:
1. defective power strip as wall outlet;
2. blown fuse or popped open circuit breaker;
3. a near lightning strike or power outage that has affected the AC section of the 2 devices.

One that you can try is to remove the VCR from its current location and try plugging it elsewhere. If it powers up (and hopefully you can eject the tape that needs to be returned), then you likewise have confirmed the electrical problem,

Alternately, you can manually removed the tape (with the possibility of wrinkling a few areas) by opening the top cover, determining the motor/gear drive that ejects the tape and just basically winging it. Of course your best bet would be to seek the services of a qualified professional.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

No power to my tv


The reason could have been a power surge(lost power in the whole house while you were out)or a lightning strike specially if you have no indication of power(no lights,no click sound),if this is the case you can start by checking the main fuse and it should be close to where the power cord comes in the tv,if the fuse is black you can expect more damage ahead and it will blow up again as soon as you replace it,if the fuse is not black replace it with the same kind and try it,if the unit does not power up you will need the assistance of a service technician to diagnose the problem.
