ProScan PLDVD3213A Woes....

06-04-2014, 04:45 PM

I was recently given a non working ProScan PLDVD3213A Television. I repair computers, cell phones, game systems, etc but I have never repaired a television so I took this project on to learn a new skill. The unit could not even be powered on when I got it and I feel that I am only a few steps away from restoring it to 100%. The problem I am having is that recently the screen started to display a large blue area with vertical lines on the right side of the screen. One odd thing about this issue is that when you first turn the unit on it does not have the problem, but maybe a second and a half to two seconds later it appears. I have learned a lot about televisions with this project but this has me stumped so I turn to the minds of men who know more than I do on the subject. Thanks in advance for any and all help you guys can offer me.

Did you try flexing the screen to see if the problem will come and go?

My opinion would be that is a bad LCD panel. It is probably ultimately caused by tab bonding failure. May or may not be fixable, it depends.

Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

I have a thinkpad p1 gen 3 20th-ct01ww. Recently I've had 2 that after windows updates, it no longer detects the battery

by deviantcode

I have a question regarding one of these lenovo laptops. I have a thinkpad p1 gen 3 20th-ct01ww. Recently I've had 2 that after windows updates, it no longer detects the battery. I have tried rolling back the bios update and that didnt fix it. Is this something that requires modifying the original bios to fix or is it bios related at all ? Is this issue common. thanks.

Intel PC hooked to X90L television picture cut-off

by Jackching

I have my Intel PC hooked to my Sony X90L television and each time the power is cycled on the tv, the bottom of the PC screen gets cut-off. Only half of the taskbar shows until i go into display settings and cycle the display size and it'll work fine until the next time I power off the tv. I updated the drivers. The graphics is UHD 630.

New project for a Lipo4 based battery pack for a battery backup that I found an enclosure from Battery Hookup

by sam_sam_sam

Right now Battery Hookup has these e-bike battery packs that are used but I am going to remove them and test them and see how good they are and maybe resell or reused them for another project this is for another day

When I get the rack mounted enclosure that I mentioned in another post I will see how well they fit in the enclosure and how much room I will have left

These battery packs are a little bit hard to get out of the enclosure because they were a little bit glue...

HP RTX 3060 with bad cap (beginner project)

by Bladiblad

I have an interesting project here. I have a HP RTX 3060 12GB VRAM GPU with a shortcircuit between a (what I believe is) a coil and a cap. The short circuit is so bad that it will trigger a failsafe on the PSU.

I'm a beginner in this field and have managed to do only very simple board repairs so far. I have basic understanding of the components (mosfets, caps, nand chips) but completely diagnosing a board with schematics would be challenging. In this case though, I'm going to hope that replacing only the two shorted components will bring the card back to life (if none of the IC's...
