TV Repair Questions? Ask a TV Technician for Answers ASAP
I have a sharp lc 52le810un TV. I had the TV wall mounted on a swivel mount and I went to turn the mount. I noticed a spark and the tv shocked me. My directv box that was connected to the tv smoked. I found out that the problem was the TV power cord got pinched and it shorted against the TV frame. Somehow that killed my directv box (no problem another is on the way :). But now after I have fixed the short in the cord the TV will not come on at all. The power light at the bottom initially is solid but then it gives some type of trouble code. 3 slow flashes followed by 1 quick flash. It does that over and over but the TV never comes on. Im thinking It could be the power supply. Im wondering what an expert thinks before I waste the money. Does this some like a power supply or something else. If the power supply was dead would the trouble light even come on?

Hi there, sorry to hear about what happened with the tv,
this certainly sounds like there is some internal damage, likely the main board fried by the short in the power line,
Can you tel me if the flashing light you saw was only the power light, or if the OPC light blinks at all too?
If so, what is the pattern?
only the power light blinks
no other lights work
I think its the power light
whats the opc light
its the light that shapped like a V
the patter is. 3 slow flashes, 1 quick flash
repeat over and over
Yes I'm here
just saw your responses, sorry
opc is toward the lower right corner of the display, for "optimal picture"
no. its the power light then. dead center
the error code you're getting indicates communication error, meaning a failure on the main board.
It's also possible there are other faults on other boards, but this is the first code that is coming up.
Are you looking to do a self repair?
Or trying to get an idea of repair costs to have it serviced?
Im a home theater installer
happened to customers tv
one of my guys ran a wire incorrectly
trying to decide if we can get it repair or just have to buy the customer a new tv
Aaah got it.
Im capable of swaping some boards. Soldering etc.
dont want to waste money and still have to buy a TV anyway
That would be my worry as well,
the short that happened is equivalent to a power surge in terms of the damage that may have been caused;
so there is a fair chance you could swap out the main board and still have to end up doing the power supply too, or the inverter, etc
yeah. that's too many potentials
I'm primarily a home theater installer myself
if this happened on one of my jobs, I'd just consider it a loss, file a claim with my liability insurance policy, and buy the customer a new tv
really. Thats awesome. Watch those wires on those full motion mounts.
but that is mostly in the interest of time. Even if I knew I could fix it,
my insurance deductible is $500
not worth the rate increase
I wouldn't feel right leaving the customer without a tv for weeks waiting on parts, and for me to have time to fix it.
That's too bad
yeah. just happened today
told them to give us to monday
If it were me, I'd buy them a new comparable tv, probably at costco so you can grab one locally,
then you could always get this one fixed at your own pace and use it for yourself, sell it to another customer, etc
What do you think a fair replacement is for that TV
52" about three years old
Considering you can get a 55" lcd for around $700 with comparable features, and the realistic useful life span on these is about 6 years, I'd think fair market value would be in the $500 range (being generous)
Maybe offer to pick them up a comparable one in the 800 range, and kick in 500 toward it if they'll pay the balance to meet them part way.
People never seem to understand depreciation and the value of what they have
And for what it's worth, you're not alone. I've never got a power cord like that, but I've pinched an hdmi and optical cable before, so I know what a pain they can be.
they cant get what the paid for it out of their heads
And it was double what the same model would sell for today.
this was our first time. I thought for sure when I got the call it was a power surge issue
I'd at least try explaining it to them, and if they balk at it just say you'll replace the tv and get the most basic model you can, knowing you can find a vizio one for 600 if you're really pressed for it.
Im glad directv replaced that box
that would have really sucked
Me too, they must have the $5/mo warranty plan on their account, got lucky there.
yep. had the warranty
thanks for all your help. let me do some tv prices checking :(
You're welcome! Sorry you're stuck in this situation, I feel for ya man.
Do you do alot of TV installations in your area
I do, yes
more full home theaters, speaker installs, etc. But I hang a lot of flat panels too
I do a good share of home theaters. but flat panels keep me busy
at least a couple a day
Ya they're good for business. Bad for your back.
again thanks for all your help. Good night
