My Avion flat screen TV has no audio. It needs an audio circuit board replacement, but I can find no one who handles Avion parts. Does anyone know of a parts supplier for Avion plasma TV's?

SOURCE: I purchased the Avion 32"

Try http://www.google.com/search?q=090-02180-I3&hl=en&prmd=ivs&source=univ&tbs=shop:1&tbo=u&ei=A3L-TKnWL5OosAPj672vCw&sa=X&oi=product_result_group&ct=title&resnum=4&ved=0CCsQrQQwAw

Also please read my guide so you will know what to look for inside the TV.
It may be the same power supply as used by Protron/Spectroniq PLTV-32 which uses an AC adapter that puts out 12vdc and 24vdc.

Please see my basic troubleshooting guide here:

Lg 60pn5700 plasma tv repair


Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Model 50LN5700. How do I repair broken screen?


You can't repair a broken screen. You must replace it.
Now, the problem is that the screen is the most expensive part of Flat Panel TV and It's not really easy to get them, specially 50" screens.
Maybe you can find some site selling it as parts
Do a google search for Parts LG TV 50" Screen
Quite probably your best solution might be selling your damagerd TV for parts on ebay or even, disember nad sell circuits boards separately.

It's a Sony 32 inch flat screen led tv. Has line going across screen about 4 inches from top and faded verticals lines across tv. Anyway to fix that


one of the circuit board needs repairing replacing. I wouldn't recommend trying it yourself even though it wont be too difficult but without electronics knowledge you could end up getting the wrong parts and wasting good money. Parts aren't cheap so get a quote from a repair guy and prepare to replace the TV if it's dear

My Dynex DX-L26-10A display is not working. The audio is completely functional, but no matter what input I am on whether it be TV or HDMI, all I get is an illuminated but black screen. Ideas?


Most often, this symptom is a result of a failing LCD CONTROLLR (TCON) BOARD but a faulty MAIN BOARD can certainly cause very similar symptoms. Unfortunately, without a donor TV to swap parts with or a dedicated test rig, it can be very difficult to differentiate between these problems.


One quick way to test this is to remove the rear access panel on the TV and then replace the TCON board with a new one, since this is the most often the source of the trouble.


You can usually find replacement supply circuit boards online by searching for your TV's model number.


Here is a link to a replacement TCON BOARD for your TV currently available at SHOPJIMMY for about $63 US plus shipping:


http://www.shopjimmy.com/dynex-569kt04260-t-con-board.htm



Just use your mouse to click on the link, which is the underlined and highlighted text just above. This will open a new web browser page automatically for you and allow you to view the information and items at the website indicated.


The repair / replacement procedure is not extremely difficult if you have some basic electrical safety knowledge and some basic electronics / mechanical repair skills.


You will need to unplug the power cord from the unit, lay the TV screen side down on something soft and flat like a bed if necessary, and then remove the rear access panel or the entire rear cover as required in order to access the circuit boards inside.


When you remove the rear cover and access the circuit boards inside, just check the part number that is printed right on your circuit boards and confirm that they exactly match the ones provided in the online listings. Also make sure that any part you order is labelled "TESTED WORKING" in the condition description. Any part with a condition description of "AS IS" is probably faulty itself as well.


The TCON BOARD will likely be hidden under its own RF shield cover plate. Just remove the screws / tape securing this protective metal cover as well. Then unclip and remove the various electrical wire connectors leading to the TCON BOARD. Then remove the screws securing the circuit board to the frame and then remove the circuit board itself. Be sure to avoid touching any large capacitors on the power supply circuit board which can retain a nasty charge even after the unit is unplugged.


Then just screw in the new circuit board and connect all the wire bundles to their appropriate connectors on the new circuit board and then replace the rear cover. Then plug in the power cord and test.


Here is a link to another Expert's solution to a similar problem which includes links to his excellent and informative set of LCD TV / MONITOR TROUBLESHOOTING GUIDES:


http://www.fixya.com/support/t10008425-when_turn_tv_picture_flicks_off


These guides will give you some idea of the various problems with LCD TVs and monitors and the associated repair procedures.


If you choose to rate BUDMRTN's troubleshooting tips by clicking on the YES THIS WAS HELPFUL icon on his solution page at the above link, then I thank you very much for your time and consideration.


I hope that was helpful to you, good luck.

take the back off the TV, locate and remove the audio circuit board, order new board probably less than $40 online . to find which one it is just Google the make and model of the TV and ask for the board blank # and revision of the audio board/ video input board if not the same board then repeat same steps for that board also.... don't be discouraged it seems like "Yea Right" but its very easy all the replacement parts are readily available for almost all flat screens right here online for cheap! repair man don't want ya to know that though! Good Luck!!!

Can i repair a broken screen on a lcd tv?


LCD stands for Liquid Crystal Display. It is all one unit and when broken can not be repaired. The only way to fix it would be to purchase a replacement screen but that would probably cost more than replacing the whole TV. You might look for a used TV of the same model with a good screen and a bad circuit board and exchange parts but it is far easier to replace circuit boards than LCD screens so if you find a similiar model with a bad circuit board take the good board from your set to make the one with the good screen work again.

My sanyo plasma flat screen tv will not come on.


For what it's worth, you can download the official Sanyo repair manual for this TV (DP42746) at http://www.eserviceinfo.com/downloadsm/43343/sanyo_dp42746.html. I uploaded it here when I had some issues with this TV last year. The solution almost always seems to be to replace the Power Board and the Upper and Lower Y Buffers. The parts and costs (from Sanyo in July 2009) are listed below (NOTE: Sanyo will not ship these parts to anyone but a repair shop):
1. V4 Y-Main (Y-Sustain) Circuit Board (Part # LJ92-01200A, Alt Part # LJ41-02759A) - USD $139.00
2. Upper Y-Buffer Circuit Board (Part # LJ92-01202A, Alt Part # LJ41-02760) - USD $64.00
3. Lower Y-Buffer Circuit Board (Part # LJ92-01203A, Alt Part # LJ41-02761A) - USD $64.00
Sanyo charges USD $10.50 for shipping, which brings the total cost for parts to USD $277.50. From my research, a shop would probably charge between USD $500 and $700 to do this repair. FYI - there is a class action lawsuit pending against Sanyo for this issue. The V4 Y-Main (Y-Sustain) Circuit Boards fail VERY frequently in this TV due to overheating. Hope this helps.

My screen went out on my 50'' nak ...how much to replace it


If your diagnosis is correct and you have a broken plasma screen unit then it's beyond economic repair as a new panel costs more to supply and fit than buying a complete replacement tv.

If the tv has simply gone into protection mode due to a failed cooling fan or if a transformer, relay or circuit board has failed then it's normally a straightforward and cost effective repair but definitely not a DIY job. Fans and relays are the cheapest repairs, typically labour for one hour plus the (usually) cheap parts, transformers and circuit boards are typically one to two hours labour but the parts can be very expensive but the total repair is typically far less than the cost of another 50" plasma tv.
