Re: Sanyo DP42647, Sparklies, off colors, occasional ghosting.
I have the same problem, same TV: It was unplugged for a month (out of town). After plugging it back and watching a couples of shows, it flickered between bad and good a few times. Since then it is doing the exactly same thing that Johnboy1313's is. However with the contrast down etc, it is better but not good enough... It happened at the end of Jan 2015. I've tried all different inputs (HDMI, Component, Composite and RF), opened the TV and unplugged / plugged every plug that it has, just in case of a loose connection without success... I really appreciate any help!Comment

Hi!
Got an 70 inch Philips tv model 70pus7855/12 from scraps and I decidet to give it a go. I'm an enthusiast but no porfessional in the electronics.
Found some advices watching youtube nad came up with this:
It came with no picture, after diagnosing it I found out that the right side of the T.con board was faulty.
I taped down the clock signals and I got a picture but the left side of the panel has less pronounced colours. Only the right 3rd side of the panel has good colors.
See attached picture.
I tried a few combinations to block individual clock...01-02-2025, 02:26 PM -
The KDL 46 LCD has occasional green overlaying the picture. It seems as to happen less often if I control the picture settings to display less brightness, picture, backlight, etc...
It often will flash green for a moment, with the pic still visible in behind and then flash off quickly. I have looked at the caps on the power board and none of them have popped. I have also tried changing the Control Board (t460hw04 V5) with a new one and still no luck. I have also swapped the ribbon cables from the ctrl bd to the lcd and no change. Im thinking of replacing all the caps or maybe ordering a...03-29-2020, 04:01 PM -
Hi,
I started posting in a different thread and I was told it was not the best ans the tv model and the fault did not match. I am copping here what I wrote.
After starting the TV it works ok for a few seconds and then starts showing ghost image with horizontal lines intermittently (except the very top). The frequency of the ghosting is steady, like every second or so, it goes from normal to ghosting every second and back.
The TV is a 49XE8096. I already did quite a lot of trouble shooting. And I got the doubt if the problem is in the panel or de Tcon.
When disconnecting... -
Need help with this unit...looks like the colors are not displayed correctly....not an expert, but looks like something wrong with the GREEN...have attached the photo of the 'home menu' and the recorded video of the Demo video that's on the TV for viewing/testing.
Where should I look for faults? Everything else looks/works ok.
BTW...have upgraded to the latest FW/SW version, but nothing changed.... -
In the above mentioned monitor, I removed the plug a few times and this resulted no power.
I opened it, soldered the dc jack and worked again.
But since then colors have changed, too bright (or something like this) and lines, eg letter, are not very crisp as they used to be, they are vague, like faded out.
I checked voltages on the main board, they look ok (according to the service manual. It' attached at the bottom):
IC600 (D9329)
pin 1 (BST) 9.6V
pin 2 (VIN) 13.5V
pin 3 (SW(Switching output)) 4.8V
pin 7 (EN)
pin 8 (SS) 2.6V
IC601...
