Coppell TV Repair offers an EXCHANGE SERVICE for a tested and functional replacement for the main board J4HEF (PCB identifier 1LG4B10Y04600_B and possibly others) as shown on the picture and used in Sanyo DP42740 plasma TV model with chassis P42740-03.

EXCHANGE SERVICE means you agree to buy a functional (possibly serviced and always tested) board under the condition to return your own old dud.

Details of the condition can be found in the REQUIREMENTS section below.


It is EXTREMELY important to verify that the board you need is indeed J4HEF!

Sanyo DP42740 comes in a number of different chassis and some of them have boards that look like the one on this picture (while others are different), but the ones that look like this are not compatible with each other.

All they will have the same stamp on the PCB - PWB.MAIN.N7AL with a longer number above it, which may differ; that number is not relevant.

What is relevant is the label stamped at one side of the tuner board (the box with the cable coaxial input).
It MUST say J4HEF or this is NOT the listing for you!

See the image of the tuner and the label so you can verify your original board is the same!


All board serviced by us come with a standard 90 days warranty of parts and labor. Customer is responsible for return shipping and Coppell TV Repair is responsible for shipping back to customer. Returned boards subject to exchange, service or refund, subject to availability and agreement by Coppell TV Repair and customer.


Upon installing and verifying its functionality you can send your old dud and receive the advertised credit subject to the below conditions.

The returned module must arrive back to us within 3 weeks of arrival of our own board to you.

It must arrive in good physical condition and without traces of repairs or tampering in order to qualify for the full advertised credit.

Modules that do not meed those criterias will be subjected to partial refund or no refund at all (depending on their condition and trade-in value).
