Have a Magnovox 42MF531D/37 and are trying to replace the TCon board. However, we are having an issue with the brown "straps" - we don't know how to get them off of the old one.

If you are talking about the flat ribbon connections that go from the Tcon board to the LCD panel, the you just have to lift up the little tab on the connector that is on the Tcon board. It should flip up like a little hinge and once that is unlocked then the flat ribbon cable will pull straight out.

To replace the flat ribbon cable just slide it straight into the connector ensuring the little flip up tabs are up first. Once the ribbons are fully inserted into the connector then flip the little tab back down which locks the ribbon into position.

Good luck and post back if this helps or if you need more assistance.

Where is Tcon board?

HELLO Kolachalam,

Tampatec is a lot of fun to watch... and can get you inside your set with a lot of confidence... I would recommend adding a WRIST-STRAP... (and more caution).

I do adore that he manages to BLOW out a collateral board because he does NOT use (ANTI-STATIC) WRIST STRAPS

He does run through a lot of internal topology of where the various parts are located... I am assuming your question was actually deeper than where your board was located

Lg lcd can a bad tcon board kill all power

Yes , it can be a short on the board that will ask the SMPS unit to protect the power so as to switch off. So even with a multi-meter check you will be able to trace the short on the board, the drivers or any capacitor that is cutting off the power which must solve the issue.

I had a similar problem with my 42 in Philips LCD HDTV.

Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors on the PSB. Many major electronics companies Philips/Magnavox, Sony, Panasonic, and others were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.

Here are some options for you.

1. Have it fixed by a professional $$$$$$$??????? (Is it under warranty?)

Remember, TVs CONTAIN HIGH VOLTAGE AND CAN KILL YOU! Do this at your own risk.

2. Open your TV and find PSB. (The board that the power cord plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. The entire board costs around $250 right now because they are in high demand right now. They can be found online. I would definitely shop around though.

3. Remove and then replace individual faulty caps. This takes some soldering skill.

Caps are inexpensive and if you can take care of it yourself it will save you hundreds.

This may be your problem. If you determine that it might be.

I have a Tip/How TO tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. Here is the Link: Fixing the Philips Turns/shuts off on its own problem. I'm working on uploading pictures to help guide people though the process as well. Let me know if I can do anything to help.

Hope this helps and if it does please rate it accordingly. Good luck.
