Hi, had a question about what you said, have a minute?

Hey there, Im fairly new at and dont know if its correct of me to just ask you directly for a little help. You hae talked about the problem i have in one of your posts. If you have time can you please help me answer this question.

I have a Dell wd4200hd which the same as Sanyo dp42746. My Y main board makes a little whine at first then same tone. The screen just went black. I disconnected the ymain from power and the tone went away, but the screen is still black. Do you think that I have more issues than the Y boards?
The ymain board model is SAMSUNG LJ92-01200A LJ41-02759A Y-MAIN

You need to replace the top and bottom y buffers when you replace the Ymain. If not, it will just go back out. If you have space, wire a 12 volt mini cpu fan near the left of the Ymain and the buffers, should last alot longer that way.

It is difficult to know for sure without some testing - by a trained tech who knows what its all about. Trial and error troubleshooting can sometimes be a poor way to solve the problem.

The TV comes on great picture and sound. After 7 to 10 minutes the TV shuts off. Most times it will come back on in 1 to 2 mins but only stays on a minute or two before it shuts off again.Model # ELDF

Power supplies are number one for going bad on TVs. I think it is worth replacing the part. Sounds like it is over heating and coming back on line when it cools.

Hey listen bulldog, I am just having the same problem! Exact same thing, standy led on, power supply and boards seem like new, but tv doesnt power up! I read a schematic at and if you follow it through it states, to change the control box!! I have fair confidence that I can replace the control box because I have experience in soldering and have built my own computers before as also swapping major components in laptops as well! So I am willing to take the risk to fix this but heres the problem!! I dont know where or what the control box is or where to go to buy a new one! POLAROID customer service is aweful, unless you know the manufacturing plant and can go there, they wont be much help! I hope this info helps you, if you got the problem fixed can you tell me what you did or where I can look to get my issue resolved! Need anything else just post here!

Wrong screws

Hey there,
The screws for the tv are metric.
I would suggest the screws supplied with the shelf are not metric.
Try some new ones.

use the ask me button, post on forum - free. You can mention that I recommended you to contact him. He might not respond this minute but give him some time, I think hes worth the wait with over 25years in tvs!

I need a universal remote control code for a Dynex television model # DX-LCD32

I can confirm that the 0441 code does indeed work for the Xbox 360 Universal Remote. I just programmed it and it works perfectly. Thanks to the person that first posted that code!
