The SHARP LCD TV worked fine in Malaysia.
When we returned to England, it did not work properly.
We tested it with both a direct connection to the TV aerial as well as to a FREEVIEW Box.
I was recently told that if we connected it directly to a SKY Box then it may work.
We have connected it via HDMI to the SKY Box but all we could see were alternating horizontal blue and grey lines.
The MENU displayed but the background lines were still there.
We tried to tune the TV to local TV channels by using the automatic setup option and this seemed to start searching but in the end nothing was found??
We connected the TV set to a DVD Player using another HDMI Port ( which works fine with our other UK TV set )
The sound came through clearly but the picture was pixelated and unstable.
I believe that there must be a setting inside the TV which can be adjusted to enable me to use the TV in England
I will have to go back and check this
It will take about 15 minutes to setup the TV again
I have setup the TV and connected only the power cable.
The Internal Menu displays clearly at first and I am able to scroll through the various options
There are no blue and grey lines visible and the background is black.
After a few seconds the Menu Display starts to flicker,
The alternating blue and grey horizontal lines then appear but they are definitely in the background behind the Menu Display
No the MENU Display flickers, the background remains constant black
OK, thanks, XXXXX XXXXX now halfway there.
Now I need the contact details of a TV Repair Company based near Swindon in South West England that will repair the SHARP AQUOS LCD TV because SHARP UK will probably decline to service the TV as it was purchased in Malaysia and it certainly is not feasible to send it back to Malaysia for repairs.
That's the only thing that I cannot help with because I am in the states and have no knowledge of what places there are in your area for repairs on a Sharp TV. It would not have to be an Authorized Sharp center though- any TV repair shop would be able to perform this repair. I did find the link below with several locations that perform flat screen TV repair for reference:
I originally logged into justanswer.co.uk so I assumed that a technician who was based in the UK would be assigned to this question.
Are you sure about your diagnosis?
what other problems could cause the symptoms that I have observed?
If possible rank them in decreasing order of relevance
It is highly unlikely that the TV was damaged while being shipped to the UK as it was well crated by the removal company and there does not seem to be any external damage.
If I hold the TV and gently rotate it in space there seems to be something loose inside which moves ??
I will have to do that tomorrow morning as it is after 10 pm here.
chat to you tomorrow
The e-mail address that you gave me
[email protected] does not work??
I have sent all the pictures via Google Cloud to the above e-mail address last night
Thank you for the reply Jon, and unfortunately nobody has sent me an e-mail with any pictures. I will inquire about this as we really need to be able to see what's going on.
However, if you want to take this a step further to isolate and repair the problem yourself, then you can proceed with the instructions below:
The first thing you would want to check for in the set, are the capacitors visually, making sure none are bulged, swollen or leaking fluid. The Power Supply is the board inside the TV that power cord directly attaches to.Any that do not appear cylindrical, or are leaking you would take the rating (In uf), and the voltage off the cap (example: 2200 uf, 50 vdc), and cross reference them at an electronics supply store.
They each solder into place with two leads, a positive and a negative. Make sure you solder the news ones in the same way, or they will explode when the TV is powered up.Make sure you are careful not to un-solder any other adjacent circuit traces when removing the old caps, and carefully solder in the new ones allowing the solder to flow into the joint. Replace any and ALL caps that are questionable. Remember- when in doubt, change them out.Try powering up the TV, and if the set operates normally, then you have solved the issue by replacing the faulty cap(s).If it does not, then you would need to isolate which board is causing the problem by measuring the Power Supply Voltages. Please only proceed if you have experience measuring live voltages on a circuit board level.Use a DVM (Digital Volt Meter) set to DC volts, put the Black probe of the Meter on an RCA jack shield on the back of the TV, then use the Red probe and probe all of the Outputs for voltage (correct voltages will be stamped on the power supply at the outputs). Do this with NOTHING connected to the Power supply but AC power, the Mainboard, and the little board that houses the Power Switch. If a voltage is missing/ fluctuating, then the power board needs to be replaced.If the power supply outputs its rated voltages, then connect the other boards one at a time until one causes it to shut down. This board would have the short causing the supply to SOS, and would need to be replaced.
