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!

Hi all,

I am leaning towards an issue with bad soldering of the graphics chip, because the problem used to go away after some time (minutes) but now it is here to stay.

Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.
The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.
Original T-con:
Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.
First replacement T-con:
I thought it might be t-con and ordered new t-con from china(supposedly tested)... -

Thanks in advance. -
Hello all
I pick this up free as a repair project for the holidays.
The original symptom was power cycling after 3-4 seconds with a single red light flash.
To remedy this I went through and unplugged each component 1x1 and discovered that when the FFC cables were disconnected the backlights stayed on and the TV did not reboot.
I tried remove one or the other to see which side of the display was causing the issue (expecting to see half a picture to show) but didn't see anything. But the boot loop only appears when the top FFC cable (right side... -
Hi all, I've recently acquired a linsar 75uhd520 TV, there was nothing on the screen when I first got it, now after finding around I've managed to get a picture but it has loads of lines running through it, I've uploaded a Google image of what the picture looked like, i will upload photos of it soon, also, I didn't get a remote with it, I've went through all my remotes trying to get one to work it but had no luck, does anyone know what remote would work this set please??...
