Question about Hitachi 61SDX01B 61" Rear Projection Television

1 Answer

No audio, no video

My house got hit by lightning, even though I had a surge protector it affected my TV. The fuse on the power supply circuit board is good. It has several LED's illuminated on the power supply circuit board, but the rest of the TV shows no sign of power getting to it. Need a suggestion, thank you.

Can you find out what Led is not on or which comes up and goes out? Most of these sets have convergence problems. Or Power Regulators.

2010 dlp mitsubishi tv is not working after power surge even though it was on surge protector. Have replaced power supply board and lamp. Now it gives error code 5 red flashes then 7 yellow.

some one will have to answer the tv faults
I just want to remind you that the average surge protector is only good for the one hit
after that it still passes power but has no surge protection

Most likely the power supply. In most models, if the lamp goes out you will still get sound. However, the power supply is not a single piece swap. I would suggest getting a voltmeter, and check the voltage where the power cord meets the power supply. Then follow the circuit pathways, checking after each component, until you find a break in power. You are getting power to that light, so some power is getting through. However, the light works on much less voltage than the rest of the television, so probably there is a capacitor or transformer that's gone out.

We had a power surge and now the tv will not come on. is there a diagnostic sequence we can perform to see if it is repairable?

Time for the repair shop, but also check that the surge protector has a protection guarantee. A number of brands do and it may cover the repair/replacement cost.

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).

The timer light keeps flashing and there is no picture after there was a lightning surge

Sorry to inform you but this is total disaster. The power supply and possibly the display boards have been compromised. TV;s and other sensitive equipment neeed a power surge protector boad. The cost to fix this is around 500-600 dollard. However if you have household insurance a claim can be made if you are covered for FUSION. Parts but not labor will be paid by your insurance company. Buy a surge protector board, $25 for the future protection of expensive electronics

Sony wega kdf-e50a10 hit by lightning now it will not turn

follow the power cord and just check the input fuse if you've got a surge protector on it it may have just blown the fuse from a spike. It doesn't hurt to try. This fuse is inside the tv.

Tv struck by lightning

You wont be able to fix the TV your self as the power circuit board may have blown - consult a qualified repair man. Buying a surge protector for your expensive electronic goods is highly recommended.

Tv after power surge

There isn't really an absolute answer to your question. The power supply affords some protection to the rest of the set when the components designed to prevent short-term power spikes activate but their primary purpose is the protection of the supply. There is surely a fuse on the line-side of the supply, then there are two more devices normally included (they cost little) that will force the fuse to blow if a certain line voltage peak is encountered, a type of resistor that is actually a semiconductor that has little effect until its design is exceeded; it then looks electrically more like a  dead short, causing the fuse to blow. The other device doesn't do much after the first few cycles of AC and is there to reduce 'inrush' current. Well-designed supplies will have fuses on the output side of the supply that protect specific voltages and circuits.
Could the low-level circuits have been affected?  Yes, but in some cases, only a working supply and time would show up some kinds of failures.
In addition, I always include the suggestion pasted below:
If you live in an area of frequent lightning strikes, investing in a 'whole house' surge arrester makes sense.
These are installed in the main breaker box and any brand I've seen comes with a $10-25,000 insurance policy to replace any dead appliances that fail despite the surge protector.
They cost $150-250 US plus installation which you can save if you are afraid to DIY.
