I will pay for the fix for the DPS-336AP PS Board

I have the same problem that everyone else is having and can't even find one to order. I saw a post on here about someone that fixes them and would offer to pay to let me know what component(s) need to be replaced to fix the board. I just want to fix my tv and sell it. Thanks much...

At board level, replacement of power supply is not a big work. But the main is what caused problem:
- by itself (regarding to quality and design of PS)
- by loads at its output broken.
Therefore, we should check and fix the loads causing problem for PS unit before proceeding to replace PS.

I have a craftsman table saw.;;;;;;;;Not a power matic. I would like to know how the fence works and how the stops and adjustments work. There is a stop on the right side of the fence that I do not have...

I think you can download a manual for your saw from this link. or this link.
Another site I have had good luck with for these older models is here. Choose the publications/reprints tab at left, then choose craftsman in the manufacturer's link, and then click on machine type to sort the list into table saws. From there you might find a similar vintage manual that has the details you need. Many models have similar parts, and the descriptions of fence operation, etc are somewhat common.
Good luck.

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.
If I've managed to answer your question or solve a problem, please take just a moment to rate this post....thanks!

the DPS-250AB is a 250W power supply, which is smaller than normal PS from most desktops. However, you should still be able to buy a spare at your local computer dealer. Don't pay more than ~50 USD for one.

Replacing a power supply is very easy. Simply open up your desktop. Your PS comes with standard cords mimicking that of your old PS. They will fit into *********** board (one big cord and maybe one smaller one), your hard-drive, your DVD-drive, your floppy-drive, etc.

The best solution is to take pictures with a smartphone of where the original cords are connected and simply copy that with the new power supply.

NOT ALL POWER SUPPLY CORDS HAVE TO BE CONNECTED SOMEWHERE! They simply come with redundant cords for future addons.

I have a vizio Model L37 HDTV10A (DPS-199AP A), Part 0500-0507-0180 (power supply), IC901 burned. I am trying to search for this part number but couldn't. I saw someone has had the same problem and he...

this might help, posted 8 years ago.

if you want to fix the power board yourself i'd try Aliexpress for the parts IC901= Off-Line SMPS Current Mode Controller (ICE3B1565), you might also consider the surrounding/connecting parts to that chip as being damaged... particularly the Zener diode.

Sharp 65dr650 color wheel noise.

I saw the same post, sells it for 69.99 but as I found out it is the WRONG one. Not even close and I'm annoyed he obviously never tried it himself. I bought a sharp replacement off of ebay but it died after 2 weeks, no refund. The Samsung model number that does not work is BP96-01579A. Maybe there is a samsung model that works but this was not it.

DPS-336AP Replacement


I was going to post later this week but I have been running perfect, without any problems at all for over 6 days now! I just went in and replaced the DSP-336AP. I took digital photo's once I pulled the back off to be sure all connectors went back on and I was careful not to touch any other wiring. You will need to also pull of the power cable connector in order to pull off the power supply cover as well as it slides out and the power connect thing blocks it. I did see that although the revision of the DPS-336AP was exactly the same as the newly purchased one, the serial number of the one I purchased on eBay was a few hundred newer or higher. I was hoping that it was a new rev and hoped that Westinghouse fixed the problem. Nonetheless, all is working perfectly once again. I paid about $150 for that DPS-336AP on eBay and there were only two sellers on eBay offering this board. Good luck and please take the time to update me as well. I suspect W sold a few thousand of these TV's and you and I will be the only ones who fixed them ourselves. Anyway, good luck to you!!!!!!!

Sharp Aquos LC-40C32U

I have the same model TV that is 18 months old. The repairman wanted $365.00 to replace the inverter and update something on it. From what I have seen online, it is mainly just loose screws on the inverter. I called Sharp and they are paying for the repair on the TV

No power at all. No amber light or green light. Power cord check out fine?? Work great then 8 hours later went to watch TV. and nothing. Any help out there ??

I've been hearing alot about the main power supply board with this model. Mostly I hear that when the power button is pressed, the relay inside will click but with no other response from the TV. This tells me that either the relay contacts are no good or that there are some serious soldering problems on the board. That would explain why it will operate for a short time then quit unexpectedly. Thermal cycling might be stressing the already weak solder joints causing intermittent contact. Personally, I'd love to get my hands on one of these boards.

If it were me and I had nothing to lose, I'd pull the main PS board and touch up the relay section by resoldering (as I believe it is more likely to have bad solder joints then the bad relay contacts). If anyone tries this with positive results, please let me know and rate accordingly.
