Re: Sanyo dp42848. No picture no sound?has anyone found the problem
I am well known for being an extremely patient person but you are certainly testing me and I do wonder if my time would be better spent elsewhere. This was the second time I have asked to to list the voltages in this manner, a lot of members dont ask twice they move on to another thread.
You said
Pson-0.49-sgnd-0.00-5vsb-0.50-sgnd-0.00-12v-00.2-sgnd-00.0-24v-00.0.
I said: list the results in a column:
pson = -0.49 Wrong? 4.9v?
SGND = -0.00
SGND = Missing
+5VSB= -0.50 Wrong ? 5v?
+5VSB= Missing
SGND= -0.00
SGND= Missing
12V= -00.2 cant guess 0.2 2.0 20.0
12V=Missing
SGND=-00.0
SGND= Missing
24V-00.0
24V Missing
13 pins 13 results
+5vsb = and so on.
Had you done so the results would be a hell of alot easier to read and you may have spotted your listing errors - assuming they are error as that is now what you said many posts ago?Please upload pictures using attachment function when ask for help on the repair

Re: Sanyo dp42848. No picture no sound?has anyone found the problem
Anyway I concede that you do not have 24VDC.
However what you need to see is if it is there initially.
You will need three arms for this or someone to help( its easier in the UK as a lot of our wall plugs have switches.)
With it all set up but not plugged in you need to probe the 24v pin and ground and keep it probed while you plug it in and still probing while you switch it on.
This will check if the 24v came on at all then went off. (As it did in that Sanyo thread I asked you to read)
(This could also have been achieved by wiring in the 2x12v bulbs Budm asked you to get.)Please upload pictures using attachment function when ask for help on the repair

Re: Sanyo dp42848. No picture no sound?has anyone found the problem
The winding tested good. No caps were failed -- at least, not as far as the TV would be concerned.
Very confused right now!Last edited by tom66; 12-03-2012, 01:44 PM.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

It is a story, that is what it is. How did you fix the bad windings on the transformer? I guess you would have to unwind it -- good luck!

This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.
Problem
TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode... -
Hello,
I have a just of warranty 70" Samsung 6-series that out of the blue stopped getting a picture, but I had sound. During the initial outage, the picture came back momentarily and then faded out. The next morning the TV worked on a quick test, but trying it again later it didn't.
When I have the mainboard disconnected from the power supply, the TV powers on with full LED brightness and stays on
When I plug the mainboard in, the LEDs go bright-->dim--off -->repeat, while the red status indicator blinks 2x
WORKAROUND: Unplug one... -
I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started βfading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.
I ordered a supposedly βnew' Tcon board this time, and... -
Hello, Last week I bought the 50" Sony X80j tv everything was working fine, untill I plugged the tv in a ups power supply 650va the tv remote control became unresponsive and the TV became laggy after a while the picture quality isn't the same as before the tv seems less brighter and the picture is somehow blurry, people's faces don't look as natural as before, there is a mini orange-pink tint to the edge of people's faces especially in NETFLIX Dolby Vision like in One Piece ep1 Alvida skin tone, my intention was to protect the tv but something went wrong I checked the ups with a multimeter,... -
Hello, this is my first post on this forum, and my first attempted to repair a TV.
My Philips 58PUS7805/12 stopped working recently. It is not that old, about 5 years. We were on a trip for a few days and when we came back, it had stopped working out of a blue (Perhaps our house was hit by a lightning strike? Don't know.)
Read from a guide that I should test if the screen shows picture with one of the T-Con cables disconnected. Did that, it showed perfect picture (first on left, later on right side).
Read also that we should test what happens if we...
