The picture of the meter shows ohms thats not were i set it too this picture of the meter is a stock picture of my meter,the setting when testing WAS SET TO D/C 200. So i was reading the meter correctly!so i will check the volts and send a pic of the meter with the setting before i start testing again..Comment

Re: Sanyo dp42848. No picture no sound?has anyone found the problem
Your attachments are failing?
Not often Tom gets in a twist.
ok fresh start - check meter ohms 200 touch probes
reading +?
tv connected and all set up powered on
meter on 200vdc black probe on ground screw in corner of power board where it says made in china and the socket CN2
With the red probe test each pin and list the results in a column:
pson =
sgnd =
sgnd =
+5vsb = and so on.
Answer the next part in a new reply post.
Did you test the "Pink" fusible resistors for continuity
Meter on Ohms 200 probe on each end.
Answer the next part in a new reply post.
Did you read the link in post24 problem was very similar and it was on a sanyo
It will show you that even if the fault IS known it cannot Always be fixed - I think in that case the OP cut that bit of the circuit out and used something else.
Also do not refer to a component as a circuit if you do not know what it is ask and/or refer to it as a component. Otherwise it is quite confusing.Please upload pictures using attachment function when ask for help on the repair

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...
