Question about Norcent Technologies PT4231 42 in. HD-Ready Plasma Television

1 Answer

My last question, I promise!

Thanks for your reply. I hope it will help me. I have 3 quick questions.

1. I am quite a layman when it comes to TV, but what I don't understand is that the TV is perfectly fine until it reaches the operating temperature?

2. If something is broken, shouldn't it always be full of vertical lines?

3. How come they only show on dark pieces of picture?

Thanks a lot. I am in Quebec and unfortunately you can't get a free estimate. I hope you understand.

No on the contrary, most defective components on a defective board will malfunction when they reach operational temperature, and a chemical called component cooler is often employed to locate the faulty component. Semiconductors are weird as some malfunction when cold and work fine when warm, but the majority will fail when operating temperature is reached. If you need assistance please let me know.

Universal Remote's (remote codes)

I am going to write a tip with my own words in it and my own idea's and what I have tried as a Tech and as a consumer. Lots of people come to flooding with questions about "remote codes" "I lost my remote", "I cannot get to channel 3" etc.

I will go thought major universal remote manufactures and try and post some codes or "code sheets" to help the influx of questions about remote codes. I would like to recommend some really good remotes first.

1. logitech Harmony (Expensive for most but overall good remote that you can update).

2.URC Digital R50 another (kinda expensive remote but will not break the bank)

3. Lets say your under the weather with funds a nice RCA,Panasonic will work but make sure it has multi function so you can use the MENU button to control your tv set.

4. I highly recommend these folks so i want to go ahead and give them a plug "i get no kick back I promise". They will find the Factory Remote that works for your TV.

Now here comes some code sheets I hope they help. I cannot grantee they will work on all TV's even tho it may be listed. I will go by manufacture of the Universal Remote first.

1. RCA
2. Phillips

We want to give credit to for displaying the codes on there link. Also credit for hosting there list of codes.

Now these links are FREE and there is no charge to you for using them. I will post more links to more remote codes as they come to me.

Please do be considerate when passing threw today and pay respect to the experts here "trying to provide" you the ask-er FREE and PAID solutions by leaving a rating or feedback. Your rating is important to us even tho if its 1 thumb. We will know quickly how to change up our support solutions.

Tv won't turn on. It blinks green then red.

Question shows tv is Sony KDF-60WF655.
Green light blinks when tv gets prepare to fire up lamp, check internal circuits then show picture on front screen.
Red light blinking shows some kind of internal problem during circuit check and protection got activated upon some failure.
Count the red light blink as you will see 3 second long pause and post it here to diagnose what section of tv got problem.
Did you replaced its lamp in last 2-3 years?

Rylee just advised me that I had a convergence problem with my Panasonic PT-47WXC43 which could cost 300-350 to repair. The TV is approximately 7 years old and I'm aware there are a lot of bulbs and other...

I replied your previous question, click HERE to read it again.
If tv shows bright picture in proper focus then it would last few more years as it is rear projection tv that has 3 picture tubes (red-green-blue) to project color picture on front screen.
Its your choice to have new tv instead of repairing this one and yes, its correct that 32 inch tv is available under 700-800 dollars.
Hope these info will help you.

I have a 2005 Yukon 125K miles - fuel guage

what's happening, is the level sensor in the fuel tank is getting worn out, and it thinks it's out of fuel when you actually still 1/2 to 1/4 of a tank left. The only way to rectify this is to put a new fuel pump in, as it is only available as an entire unit. If you can live with it, it'll probably last quite some time, but if not, you'll have to look at a pump assembly. Hope you get it situated soon! Feel free to reply back if you have other questions

Please reply couple of questions about TV to guess what could be wrong.

1- How many times standby light blinks, there would be interval of 3 seconds in blinks so count pause to pause.

2- Please intimate exact model of TV, written on sticker pasted at back of TV. That will help me to check its schematics.
