Coppell TV Repair LLC offers a REPAIR SERVICE for power supply board RUNTKA935WJQZ based on DELTA DPS-162KP-1 (printed on the board) as shown on the picture and used in Sharp LC-70C8470U.
HOW DOES IT WORK
Advertised price is the maximum price you will pay and includes the return shipping costs within USA. Surcharge applies for international returns.
You start the process through the orange button on the page by filling a short form with your contact information and a brief description of the problem.
An email with shipping instructions is automatically sent once you submit the form to the email address you provide.
You then package and send the board to us. You pay for the shipping to a carrier of your choice and nothing to us at this point.
Once we receive the board and open the box we test it and act depending on what we find out.
If the board arrives in working order you will be charged with a a diagnostic fee of up to $25 plus the return shipping costs, i.e. less than the advertised repair cost.
If the board is bad then we attempt to repair it.
If we succeed we send a payment request for the amount specified in the listing.
If we fail to we send you an email with details and usually only request that you pay for the return shipping and nothing else.
Please make sure your TV has the same board before proceeding with this service or contact us if yours is different to see if we offer repair service for it.
BOARD FAILURE SYMPTOMS
Typical power supply board failure symptoms include:
- Totally dead TV, showing on indication of power , no front LED and no response to attempt to power on via unit or remote power on button;
- TV showing standby power LED and (usually) responding to power on command by briefly changing front LED indication color before returning back to initial state. Depending on the power supply there may be audible click coming upon power on attempt and subsequent powering off and returning back to standby mode.
- TV taking a number of power on attempts until it finally manages to power on and stay on. This symptom tends to usually gets worse over time until a point comes where the TV simply fails to power on.
Even though likely, neither of the above is 100% guaranteed to be caused by a failed power supply board. A TV may be completely dead if the standby portion of the main board is damaged and may shut down for a number of other reasons beyond faulty power supply.
The list is also definitely not complete, i.e. there are a number of other ways in which a power supply could have failed resulting in a number of different symtoms.
Finding a blown (open) fuse on the PSU or finding visually defective (usually burst and burned) components is a very solid indication of a power supply needing a repair.
Finding swollen electrolytic capacitors is an indication of capacitors that need to be changed, but is not a guarantee that whatever problem your TV is experiencing is coming from those capacitors as they may be bulged and still functional for some time.
Typical turnaround time is 2-3 business days.
This is the time it takes for a package that was received to move up the queue and get opened.
Once we open the package we usually have about 1 hour to get the case resolved or we will likely end up losing money on it.
Sometimes, depending on situation, we may leave opened box and make another try on the next day.
Note that it is not guaranteed that the queue will take exactly 2 or 3 days to process. Sometimes - especially after long holodays - it can be larger and take longer.
We do our best, but we have no efficient means of managing the work load on demand.
REQUIREMENTS FOR THE BOARD(S) SENT IN FOR SERVICE
The board(s) we receive must be physically intact and must have not been tampered with or serviced before.
The advertised flat rate for repair service is only valid when the above conditions are met.
Exceptions are possible and often applied for minor repair attempts, but we reserve the sole right to judge if and when we would consider a repair minor.
If we receive board(s) that fails the above conditions we will contact the sender and usually offer two options: 1) returning the board(s) for the sole cost of the return shipping; or 2) continuing the repair service at a higher cost in case of success.
It is also possible, depending on the condition of the board, to eliminate the second possibility and just flat our reject having to service the board.
Subject to situation and availability we may also recommend replacement of the board, again at the higher than advertised price for repair.
In all cases you will have the option to receive your own board(s) back for the sole cost of the return shipping.
