Re: sr 3000 tvs working but have a line on screen
Looks like your verticle oscillator, verticle amp transistor or a bad yoke. check the verticle amp transistor first. be sure to unplug Tv and discharge the CRT. They can hold a charge for days. use a HV probe or a long screwdriver through a 3 to 5 watt resistor to chasis. before putting your hands in there. CRT can hold a 35kv charge with a
fair amount of current when dischargingComment

Re: sr 3000 tvs working but have a line on screen
I should have mentioned our family used to have one of these TVs same exact model make sure you don't have cold solder joints on the vertical oscillator or the vertical output transistors also there are some fairly large heat resistors and the solder could be bad underneath the board there. basically go see the mainboard make sure that you don't have any cold solder jointsDid I leave the soldering iron on?Comment

Re: sr 3000 tvs working but have a line on screen
I think that's too old to have a service menu. It'll likely be full of trimpots.
A working TV? How boring!Originally posted by PeteS in CAComment

Has one here really gone through fixing laptop screen vertical line(s) by repairing/replacing its Embedded DisplayPort (EDP) cable, so would recount and share the complete steps of the process here now?
As most, if not all, believe the laptop screen vertical line(s) caused by defective Embedded DisplayPort (EDP) cable which slipped and passed through either laptop screen hinge but post here is asking help to elaborate definitively the useful, real knowledge of repairing in the most complete, correct way, esp. can decide/determine whether the cable can still be fixed or must be re... -
Hello everyone, I bought a Microsoft Surface Pro 5 and the touch doesn't work. According to what the previous owner said, the screen stopped working after an update. The screen has no physical damage, and the touch works for 1 second when it turns on and then stops working. I've tried updating the drivers, formatting, and returning to factory defaults, but nothing worked. Can you help me? -

Hi,
I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on... -
Hi guys, I have aquired a LG 55EG920V for very small amout of money.
I have jumped the Power on, DRV_ON and 3,5v pins just for the screen to show a black screen with a green line offset to the left.
Connecting everything together, shuts the tv off automaticlly after a couple of second( LG protection?)
Tried with a spare MB and the original, both the same results.
But if i unplug the 12v rail to the tcon or the larger LVDS to tcon, the tv turns back to the one line and dosent shut off.
Could this be a tcon issue or something...06-17-2023, 06:18 AM
