Question about Gateway GTW-P42M102 Television

Main Power Board

My 6 yr old set has been diagnosed with a bad Main Power board.
Gateway wants $250 for the part. Can a lay person replace the board?
Can I just take off the back and plug in the new board?
Thanks!!

The power supply board can be changed without any knowledge of repair but there are sometimes adjustments necessary if the picture is not normal. Many times it is fine. There a 4-5 voltage adjustments that would take some knowledge and a meter to accomplish. You need to hope it was diagnosed properly first. If it is completely dead the p.s is a good possibility. If it clicks on then back off almost immediately it is not likely the power supply.

Main Menu and lock cymbol keep coming on screen. How do I get rid of them?


Wendy ohlsen, I know you really like your E173FP, but it is quite "old" in CCFL back-lit lcd display years. It could be 4 to 6 years old. Retrevo .com lists unit as "time to retire" ,, Please reply back with the "date of manufacture" from rear of unit. Tell me if unit has a "lay on floor" power adapter or just a plain old "line cord" that plugs into the wall. When "strange stuff" starts to appear on screen, problem is most likely inside the unit on the power supply board. Let me know if your husband or boyfriend can assist you with an internal visual investigation of unit's power supply board. See YOUTUBE video clips of repairs being done on typical Dell units first. Pay particular attention to BAD CAPACITORS being replaced with new ones!!! 12fixlouie

It can be due to unstable DC power from the power supply due to bad caps, or bad main board (I had to replace my main board, and later on the inverter boards). You may want to think about putting money into this TV.

When turned on, monitor power light comes on for a moment and then goes out. Monitor eventually comes on after several minutes. The same happens if the monitor is left on but goes into sleep mode.


This is a common problem on these monitors. There are three or four capacitors in the power supply, three on the inverter board and anywhere from 2 to 6 on the main board that go bad.

The number on the main board depends on how long the monitor has been having problems before it was serviced. The longer the wait, the more capacitors will have gone bad.

The power and inverter boards are easy to repair, the main board is not. As mentioned, it is a multi layer board so removing the old capacitors and the old solder can be troublesome. I would suggest you have someone experienced at soldering repair the main board.

Btw, our shop would charge $60 labour plus $2 for each capacitor.
