Gateway GTW-P50M203 plasma tv blinks

I have a Gateway GTW-P50M203 plasma tv. It started blinking when first turned on. Blinking would last a few minutes then clear up. Then blinking lasted 20 mins and then clear up. Now just blinks and never clears up. Any ideas?

Sorry to tell you a common problem with these sets. It is a bad capacitor in the main power supply.. There are really about three of them that go bad from time to time to cause this problem... If your not a tech you should find an authorized repair facility as a non authorized is not going to know what to do to fix it and it will most likly cost you double to repair. Good luck and let us know how you got it fixed.

Good day.
First, Have your tv 's circuitry be resoldered. this might be a case of loose contacts particularly along the crt circuitry. the longer you operate the unit at this condition, the faster you are counting the possibility of shortening the lifespan of your tube. 9 years is quite a young age for a unit which has an average of 18years.


response is highly appreciated.

SOURCE: Gateway GTW-P42M102 / Won't come on

Had the same problem... drove me nuts... I figured what the hell!!! I started pulling boards out, and on the main power board I dicovered a visual indication that one of the main capacitors "M105k" took a ****. Ordered it for $1.29... presto, works like a charm! I had to remove both relays and manually rig them to the on position for troubleshooting purposes. I'm replacing them with new ones. Let me know if this helps!

SOURCE: Tv cuts off and green light flashes

If your set was manufactured around July 2005, you may need a firmware upgrade to solve this issue. On the Sony website you can enter your model # and serial # to see if you TV is affected. If so, it is easy to have done and may be free from Sony. It sounds like the issue they described in the writeup on the required formware update. I had mine done within few months of when i bought it (purchased in Dec 2005) and it has been working flawlessly since.

Good luck!

I have a Gateway Plasma TV, model GTW-P46M103. I am not getting a picture or sound.


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Tv turns on for a few seconds then shuts off and the blue power light blinks.


Mine never turned on but the blue power light would blink.I disconnected the upper y buffer and got light on the bottom half of screen and the blinking stopped.I have the upper board on order and I think this will fix my problem.There is a blink code somewhere,just count how many blinks.Start pulling connectors from power supply and when it quits blinking you've found the one,could also be the power supply with bad cap.

SONY-LED BLINKS 10 TIMES


OK, 10 times is HV protection (High Voltage) and problem can be in D board and Q8013, Q8014 can be shorted along with R8051 open.
also IC8005 can be damaged.
All above parts on D board.
I would recommend to get related service manual for proper diagnose of problem in TV.
Good luck.

I actually bought the 5 year warranty when we purchased this new and it was still under warranty. Gateway is sending us a brand new TV. No need for me to try to fix this, but thanks to all involved.
