There are thin white lines across the top of the screen, 4 or 5". Doesn't matter if it's tv or movie. Occasionally seems to disappear, but then returns. Suggestions?
The filters or capacitors needed to be replaced--in this case only 2 of them, but the same problem could have been caused by more. The parts cost $5 apiece, and the process took less than half an hour, but required a repairman.The filters or capacitors needed to be replaced--in this case only 2 of them, but the same problem could have been caused by more.

Diagonal (left to right) lines on the top of the screen is an indicator that a capacitor in the vertical section is about to fail. it has lost its capacitance. This of course would require a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.
Additionally, pls bear in mind that the Toshiba MW27FP1 is a combination VCR/DVD/TV and chances are there would be a myriad of printed circuit boards, wirings and mechanical assemblies internally.
If you are still considering a DIY and have the service manual/schematic diagram accessible, pls post back.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards. Thank you for using FixYa.
I would say interferiance or also can be a capacitator inside or a malfuntion you should take it to a tv repair guy it is not so costly just for a check up or a service

If your LCD TV or monitor has stopped working, or is displaying one of the following
symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can
examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life
of your monitor or TV by several years.
IMO Seriously for $119 it's not worth it.
However, it does sound like a capacitor problem
If you are "Serious" about fixing I'd find a TV repair Forum.
Else I'd go here and get a new one.

When CRT TV's show only a white/bright line horizonatlly It is a failure of the flyback Transformer. Not all that costly to repair. Your old TV will probably still be working when all the latest plasmas and rear projections have been laid to rest. Fancy junk TV's dont get any better programs than those old reliable ones
Thin white dashes on top of screen is PERFECTLY NORMAL. It is nothing wrong with the TV, it is the broadcast. What you are seeing is the very bottom of the timecode running. It doesn't happen all of the time or all channels. It usually happens with old 4:3 commercials predating "Digital TV." This is mentioned in your Users Manual. You should be able to adjust the horizontal/vertical position in the menu settings.
Dear simon,
Seems like a simple problem. In all likelihood, one of the Electrolytic Capacitors in the vertical Output stages has failed.It could also be a cold / dry solder, as symptoms seem to disappear when you tap the set.
But, do not try anything thing at home. A proffessional Techie should fix it up in 15-20 mins.
Definitely worth the spend.
sounds like you have a vertical sweep problem. Where the fault lies cpuld be the vertical output IC the verticle b+ feed, could be the capacitors in the vertical circuit?? Your gonna need to troubleshoot thr vrtical circuit if your not a tech thin my advise is to take the set to a pro for sn est. Good Luck
Already tried unplugging--no change. Another suggestion, please?
Manual has nothing about adjusting verticals--how would I do this?
Required a repairman, but the diagnosis was correct.
