Hello all ! My 42 inch Daytek TV is broken. I tried everything to fix it but.... no success. I know which PCB is defective but i cannot find a replacement part for it. Daytek doesn't sell parts anymore (actually i think the company shut down) but there must be somebody who knows where to get these parts. PLEASE HELP !! the TV model is : DM-42A and the PCB i am looking for is; PLYM02: Thank you !

    Hi reyjoshua07,
    I am very thankful you answered my question about the 42'' Daytek LCD TV but i think i misunderstood the way FixYa works. I thought i could see the solution and then decide whether or not i should reward the expert depending on the value of the posted answer. I am honest and i would have liked to see the offered solution before !!

    Thank you anyways, i appreciate your fast response.

The main board the the 42A is no longer available. We have two of them here we're saving for parts and both need the main board. This is a common problem where the power regulator on the main board blows and something else on the same line shorts (actually I think multiple components short). There may also be one or two vented capacitors in the same circuit. There is nothing that can be done to repair the board and it's no longer available. Unless you can find a working board on eBay or some other place I'm afraid you're out of luck.

Hi mojo_686,

If you can't find the exact part for your Daytek TV in a local store or repair center, I recommend to contact the manufacturer directly. If system is still in warranty they will set up a free service and repair for your unit. Please click the link below for the complete contact information of Daytek.

Hope it helps.

Thank you for using FixYa.

    Yes Daytek has shut down. This company was, at one time, the #2 seller of monitors in Canada. Because of so much junk being imported and called "electronics" now, some decent companies like Daytek can no longer compete.

    The problem you are having is a common problem with this model. There is a short in the power circuit on the main board. It's not the regulators, although I believe the large 5 pin switching regulator is bad, but if you remove it the short is still there. I have personally tried several times to track this short down but have failed miserably so far. The boards are no longer available. Unfortunately, I believe your TV is now a boat anchor. The only option I can see is a very complex and time consuming option: Look around for a main board from another manufacturer that can run the same LCD panel: LG Phillips LC420W02. You'll have to modify the case and likely the connectors from the power board so they will plug into the replacement board correctly with the correct voltages in the correct pin positions, the Backlight On signal connected properly, and the control/IR and audio connectors wired properly. You may be able to get the TV going again. Make sure you get a board with the tuners on it if you need them. Personally, I'd give a mod like this about a 50:50 chance of working if done by someone who is good at electronics.

    I was going to add this as a solution, but ONCE AGAIN fixya.com is not working properly. When I try to post the solution it tells me to "please enter a valid product" even though I have already tried "daytek tv, daytek lcd tv, daytek dm-42a".

    I've had so many problems with fixya over the last couple of years (since they made the last major overhaul of their site) that I've had it now. This is the last time I will bother helping anyone here. I'm no longer typing in a long solution or bit of information to help people only to find out that I can't post it, or the site loses it, or the posting doesn't work.

    What a waste of time, especially considering I have a high ranking and that I always help for free.

    Sorry guys, no more help from me.

LCD tv Vizio 42 inch has vertical colored lines completely across (vertically) the entire screen. Here's the picture: [IMG]http://i22.photobucket.com/albums/b320/Relicario/lcdtvverticallines.jpg[/IMG]...


hello imvega7, as i know, 42 inch is a plasma display TV.
Refer to your image, and my experience that symptomp because of connection between buffer PCB and panel. Some cases, dirty conection may cause this symptomp.
Un plug power cord, open rear cover, fine pcb on upper or lower panel.
unplug flat cables from pcb buffer, clean soket using a brush. And also clean flat cables using celaner or alcohol.
Wait untill that conection dry. reassembly and try it.
i hope that help you.

I have a LG 42 inch plasma tv. Model number RU 42PX11. Suddenly the screen is not showing any sound or picture. No idea why? Cable is working (confirmed on another tv)


Hello, My name is Dave, Are you willing or able to remove the back cover from the TV? If so do you know how to use a DMM (digital multimeter) or at least know some one that dose? My reason for all the questions is in order to figure out what PCB board is bad you need to at least test the fuses on all the main PCB boards (Y sus, Z sus and Main power supply). To do this you will need to have a DMM that can test for continuity. Please feel free to give me a call or message me if you have any questions or if you would like some additional help!
