Stop that and just list the results as I asked you to - Are you using that ground screw we can see in the pictures for the black prob.
And did you do the first Ohms probes touch meter test.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
I think you should go back and read how I asked you to post the result.
There is nothing worse than being faced with a long line of numbers to decipher.
Oh! Sorry, there is - its a long line of numbers where several are listed
totally incorrectly and some pins are missing.Please upload pictures using attachment function when ask for help on the repair

Pink resistor is that from primary to chasiss? It should normally read open. Please be patient. We are busy. I have a maths test to revise for.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

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 ‘fading' 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 ‘new' 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...
