When turned on, the screen has waves in it across the top and flickers. It is unreadable. When the TV warms up it seems to be better but is starting to flicker or flash all the time now.

Hi,
Your Toshiba TV has hyperboard inside and there are few electrolytic capacitors (may be 10) that need to be replaced.
If you are comfortable with soldering parts in PCB then go ahead or ask help to any friend that knows electronics stuff repair.
Let me know further query.
Thanks.

Sony pfm-42x1 flickering screen when turning tv on


OKAY I found the Problem!! Bad Caps Compositors. I Proved this in 2 ways. First I took off the Back(always make sure the TV is UNPLUG) In the photo above I put my finger on the capacitors. I found some that where NOT FLAT ON TOP(You can kinda see in the photo too). I could feel a little nipple on top.(Some times you can see if their busted open but not in this case) so I felt them and the bottom right and top left area in red in the photo where not flat. I took my dryer(My wife really) and warmed them up for about 2 minuets each then another minuet rotating back then forth. I leaned the t.v. up to lean on the frame and plug it in. I continued warming the capacitors up and in about 2 Min the T.V. has stop blinking. Much better then the 20-30 min. So the hunt for the Capacitors is on. It will be some work to get the boards out. If everything is done delicately The Soldor job is easy for me. I am going to buy the 8 but replace 1 board at a time until the TV works and put the other on the side for next time or put them up on E-bay. I hope this helped Please like if this helped you. ea0a96a3-fb82-4ec0-89f4-76b4080e9c6e.jpg 1b190ebd-5d69-4553-a009-840d29ab4c87.jpg ab9b51d0-6e1d-4cce-b822-e80d0fde9163.jpg

After a period of time, vertical lines appear on the screen. Looks like jail bars. Sometimes turning the TV off, then back on will clear it. All channels. I replaced the projection bulb about 6 months...


no solution, same sounding problem though. last year we were getting lines through the screen and flickering and then the bulb burned out. had it replaced, 2 months later it did it again (they wouldn't stand behind the bulb so we had to buy a whole new one) this time had the bulb and ballast replaced because the repair guy said usually you have to replace both (why didn't they replace them both in the first place?) .. a year later and it's doing it again.. we get the flickering of the screen going on and off and horizontal lines that flicker across it. after turning the TV off and on a few times it seems to go away (or after it warms up)

i know know if i should order another bulb and ballast and spend the money for it to happen again or if it could be something else

let me know if you find a solution.. carolynspranger@gmail.com

White Line Across Television


If it is just a collapsed picture and view as a white horizontal line across your screen. Loose vertical IC connection or is start ailing. Best is to reflux its pin with a new lead or resolder it.

But I don't recommend you do it yourself if you don't have experience doing it.

Nasty voltages may caught you.

Toshiba 42H81 - Screen flicker


Since the problem initially would correct itself, it suggests a poor connection somewhere that "heat" would resolve. If you can solder, try resoldering any joints that appear to be grainy or have rings. Please note that these sets will retain high voltages that can be dangerous even when unplugged. If the resoldering fails to resolve the problem, let us know and we'll look further.

Thanks,

Color flickers on and off


I went to the Sony support page for your model.(link below)http://esupport.sony.com/US/perl/model-home.pl?mdl=KP61V85&LOC=3
They are undergoing maintenance right now, so I couldn't find any answers for you. I would check back with the website to see if they can help you. If the Standby timer light flashes, you may need to have the TV repaired. There is a "Hot Topics" section for "How to troubleshoot television picture issues" that will probably be very helpful to you.
