Re: Sanyo CE26LD81-B TV Troubleshooting
You spend £24 on parts when you can buy a new used PSU for £18 on eBay?

Re: Sanyo CE26LD81-B TV Troubleshooting
other bits and bobs also, be less if minimum order was less than 5 for most things
Also got 2 other things to repair, which 1 is also made by vestel under other brand so likely will have the same parts on it.
Also forgot about fleabay
*shrugs* Practice also, learning experience.Comment

Re: Sanyo CE26LD81-B TV Troubleshooting
Ok still no go
Replaced both caps with those suggested and replaced a few other caps that looked suspect.
Repaired the IDTV board also.
Next tried unhooking the IDTV board, still nothing, LED lights up blue on the front, power it on, nothing.
So now really scratching my head....Comment

Re: Sanyo CE26LD81-B TV Troubleshooting
Think that damp might have gotten in or the panel is goosed, large darker S shape in the middle of the screen when an strong LED torch is shone at it.
Rats....learning curve, chalk things up to experience methinks...Comment

Yeah, could be... Sucks.

Re: Sanyo CE26LD81-B TV Troubleshooting
Well as someone else said to me, "your soldering has improved" so thats one plus, at worst I'll salvage the caps etc from the boards.
Unless anyone else needs parts from the TV.
drat thought I was onto a free telly there....:/Comment

Re: Sanyo CE26LD81-B TV Troubleshooting
Keep the main board and DTV board. You should be able to get £20 for main board, £10 for DTV. If it has an easily accessible inverter, that's worth at least £20. When removing the main board note down the panel model number -- it will be locked to this panel (though it can be changed.)Please do not PM me with questions! Questions via PM will not be answered.

Re: Sanyo CE26LD81-B TV Troubleshooting
Fair enough, thanks for the advice
Much appreciated.
I was actually going to ask if a panel from a different display could be used to test the boards. (I have a 27" Baier TV with a working 720p panel)
Likely just strip it for parts and ditch what I can't sell.
Thanks again for your help.
Next....perhaps try and sort the baier out or my 24" el cheapo 1080 monitor.Comment

This is my first attempt at troubleshooting a board like this, I know I could just buy a new board but I'm curious to figure out how this works. I've been testing different components in the evenings this week and I think the problem is with the IC failing to start up for some reason. When the board is plugged in there is no standby voltage.
Then today it randomly sprung to life like a zombie but shortly died thereafter. I have no idea why it would have done that and its the first time I've seen it running. I discharged capacitors on the board last night, then it was sitting today.... -
Hello,
I need advice in troubleshooting Telefunken TV (it is actually Vestel). There is red Standby light but TV cannot be turned on either by remote control (which is good and tested on another TV) or by actual on/off switch at the back of the TV.
Power board is Vestel 17IPS71 and I'm not sure about the mainboard, it seems like 17MB82S
Both boards are shown in the attached photos.
What is normally first that is checked in this case. I have removed power board, make sure it has no dangerous voltage on the big caps and check many components (transistors and diodes)... -
Hi. I got a Vizio with no power or standby, and won't turn on with remote or button. I checked the voltages on the connector and all read 0.00V or nearly 0(0.050 ON/OFF pin). None of the pins are labeled STB for standby although I do see some 5V pins. Other than the obvious standby led, which isn't coming on, is there a way to check for standby voltage on this PS. I'm trying to see if my problem is the PS or mainboard. Some Vizios I have fixed with no standby led me to think it was the PS but it turned out being the mainboard. Any experience with this set would be greatly appreciated. -
Hi all.
I started a thread while back regarding TV power supply standby circuitry as it is something I am not quite on top of.
SMPS theory and function is becoming more familiar, however the standby part is still a bit of a mystery.
Anyway, a friend has this TV with the above mentioned power supply board which has no standby voltage, nor any other voltages leaving the board.
The mains AC comes in fine, gets filtered and rectified with power is on the main filter cap as well as the transformer and drain pins of the ICE3B0665J, but that's it.

Hello,
I am trying to re-purpose this power supply that I saved years ago from a tv with a cracked screen for a monitor but that is not really that relevent at the moment. I do not recall which tv but a google search looks like it is from Wharfedale LTF37K1.
You may notice I made some alterations moving some components to the top and some wires which are from a 5v regulator I fitted to the 12v output as the monitor requires 5v. The standby was already at fault from the beginning, it has nothing to do with the alterations...
Years ago it had some bulging caps...
