Ive had my 55 inch Sharp Roku tv not even 2 years and now it won't even turn on. Completely black screen with no sound.
Red light at the bottom left of tv is on and flickers but no response to remote or manual on/off button.
Yes, I attempted to contact the manufacturer. I have no idea why the istuation has stopped your calling centers ( per the ATM ).
Yes, I've attempted basic trouble shooting.
Unplug cord from Wall and tv and wait...
Held down the reset button.. With no changes.
Tried whatever codes for the remote.
Nothing seems to work. Any advice would be greatly appreciated. Surely a well kept expensive tv just doesn't die randomly and require a new one.
My 55" Sharp Roku TV LC-58Q7330U was purchased September 2019. It lasted ALMOST 16 months.
One morning a family member tried to turn it on, and it did not turn on. What we noticed was the blinking of the power/INPUT light on the television. Like yours, it blinked in a series, the light became bright then dimmed itself.
We called the toll-free number from the manual of our device and were told that our warranty was up, and there was nothing they could do to assist us.
We emailed Hisense (the company over the TV) but was able to do a direct chat with them online.
We have no idea what needs to be replaced on our model. When we inspected it, NOTHING we were encouraged to look for in researching our TV was amiss.
To purchase a new main board or a power board (LC58Q7330U Hisense Replacement Parts - Hisense (encompass.com)) would just be guessing and together would come close to the price of a new TV.
It was a nice TV while it lasted. If this is what the future of television purchases will be like, I'd rather not own a television. Technology is supposed to bring positive progress and be effective and efficient. The 55" Sharp Roku TV LC-58Q7330U was lacking in longevity.
roku tv's are notorious for this issue. many end up in landfills as a result. try shining a flashlight while it is on. you will find your tv most likely is working but the terrible blacklight system for roku tvs. doesnt matter the brand will fail prematurely. need to enter k mode and reset the system.
this is a major software failure on roku not sharp not any brand. straight software problem. not a hardware issue.
my tv is stuck permantly this way and it was one of the biggest wastes of money in a while
Thanks for the post.
The issue you are experiencing may be hardware related. Have you tried contacting your Roku TV manufacturer to see what insight they can provide?

My house burnt to the ground about 17 months ago and I bought 3 55" sharp roku tvs and my boyfriend bought one at the same time. One of mine went black, no sound about 3 weeks after I bought it. I called and they replaced 2 boards, I wish I could remember which ones. But he said omg you bought 4 of these? They are junk. They won't last you 2 years. He was spot on. 1 died 13 months, one 14 months, and the last one a couple weeks ago. We're talking over $2000. I taking to every head honcho and they don't give a **bleep**. I'll never buy a sharp or a roku again. You basically stole from a family that already lost everything. Scum. Just scum.
