Searching for parts

Help! I'm not sure how to identify which part number is correct?

The first step would be to follow the instructions in the listing to find which board you should try to replace first. You can also watch the YouTube videos here. The only real way to properly troubleshoot / diagnose is by trial and error since there could be several boards that show similar symptoms and possibly more than 1 board not working. Sometimes the symptoms change. We typically recommend purchasing all the boards that you suspect will fix the TV so you have all the parts you may need. The only way to be sure to find the right part is to open up your TV, remove the board and search by the numbers on the stickers. You may have to search several before you find the correct one. If you search by TV model it will most likely NOT work. Please contact us for help troubleshooting, diagnosing or finding the correct part number.

Can I search by the number directly printed on the board?

No. You can use it to help find the part number but using just the number printed directly on the board will almost never lead you to the correct part, as there are many boards that are not compatible with each other but have the same board number. If you need help locating the part number use the live chat located at the bottom right corner of the page.

Can I search by TV Model number?

Technically yes but there is a high chance you do not purchase the correct one. Manufacturers will often make a TV model that has different chassis and boards inside. It is best to find the part number usually located on a sticker on the board.

Can you repair our TV for us?

Unfortunately, we no longer repair TVs but if you need to locate a certified TV technician you can find one at or

My part doesn't show up, do you have other inventory not listed online yet?

YES! We have thousands of parts that have yet to be listed here on the site so please visit or contact us using the chat in the bottom right corner to see if we have a part that isn't listed.

My part is not in stock, when do you get more in stock?

We update inventory daily and are always getting more. You can sign up for a product out of stock notification when it comes back in stock. Contact us in the chat for an idea of when it may come back in stock or possible compatible parts that you may be able to use.

We found a cheaper price than yours. Do you price match?

Yes, we do! Make the purchase if you haven't already and send us a link of the competitor within 30 days . The competitor must have it in stock and have a similar warranty. We match price after shipping since ours is free (cause we're probably better than them) and we do not match all eBay listings / sellers. If you have an eBay link send it to us and we'll take a look and base it case by case. We don't price match and give an additional customer discounts on top.

Why do so many boards show up when I search for my part?

If there is more than one part (discount listings not included) then you are probably searching by the board number or TV model rather than part number. Locate the part number by trying to search by the numbers listed on a sticker. Contact us via chat if you need help finding the correct part number.

Your price is more than I have! Will you take what I can offer?

Possibly! You can submit a best offer and it will be addressed within 1 business day so keep an eye on your email. We will accept, deny or email you regarding a counter offer.

Our standard warranty is 180 days (roughly 6 months). We offer a 1 or 2 year extended warranty with varying prices depending on the cost of the board.

Troubleshooting Help

Boards - Check out Tampatec's video below for help with general troubleshooting and diagnosing problems with boards

My TV doesn't turn on. What board should I try to replace first?

We are here to help. An issue with a TV turning on may not be as straight forward as it may seem. Please follow the steps below to see if you may have to replace any other boards before trying the power board.

*NOTE* LG & Vizio TVs must be plugged in for 5 minutes before it will turn on after replacing any boards*

*For main board replacements check firmware upgrades online - We can not pre-install them*

1. Inspect ALL Ribbons and connectors. Any tears or bad connections between boards must be replaced FIRST

2. If you have any of these boards, it should be the first board to be replaced
A) T-Con Board - Video Problems (No Video with standby light on, audio but no video, vertical lines in the screen, half the screen not working, grainy, distorted, or color problems in screen)
B) X or Y Buffer Board (Plasma TVs only) - Standby light is on but no power
C) Backlight Inverter / LED Driver - No Video with standby light on. Please do flashlight test below first.

3. Main Video Board
- Standby light is on but still no power
- Do the flashlight test. Turn on the TV and look very closely at it with a flashlight. What you're looking for is an image on the screen but the image is not backlit so it's very hard to see. This would be similar to turning the backlights on your phone all the way down. If this is the issue you have to follow the cable from the backlights and whichever board it plugs into is the one you should try to replace first. It's either the Backlight inverter, LED driver, main video board or the power board.
- Either video or audio does not work (if there's no T-Con board in TV. If audio but no video try the T-Con board first)

4. Power Board - No power AND standby light does NOT turn on. If standby light is on try other boards above
- If your power board is clicking or buzzing it doesn't necessarily mean the power board is bad. There could be a short in a different board that is causing it. Please contact us for help troubleshooting this issue. You have to be very careful and follow the Safety Tips when troubleshooting

5. Panel / Screen- No power, distorted picture, lines, slow motion, half screen, faded in / out. Panel problems are usually not worth replacing. They could be as expensive as replacing the TV.

If you've watched the video, read the troubleshooting and are still unsure of how to diagnose the TV, please message or call us for more assistance before purchasing! We offer FREE PROFESSIONAL TECH SUPPORT! The only real way to properly troubleshoot / diagnose is by trial and error since there could be several boards that show similar symptoms and possibly more than 1 board not working. Sometimes the symptoms change. Be patient with questions from us and exchanges!
