Picture curved horizontally at both ends of a Sony Trinitron TV


Just about any tube TV is a 4:3 picture shape and most current TV is 16:9. so there is a compromise to get them to work together. Unless you are viewing retro TV shows, you should adjust your Digital converter so that you have a black band top and bottom (yes you are giving up screen). The alternate is to keep 16:9 and give up left and right sides of the program. Or properly recycle the TV and buy a LCD screen. Even used, smaller ones can be had for 20 bucks. I bought a 32" for 30.

In case I have this wrong and this is a new screen problem, make sure there are no magnets anywhere your TV. They distort. Have you tried back adjustment screws? Use a mirror or have a friend help. Look especially for pincushion adjustment.

SCREEN REDUCED HORIZONTALLY BY OVER 50%


Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy. Surf the site with patience. Pull up older posts.

I HAVE A LC401EM2F EMERSON TV 2 YRS OLD. WHEN I TURN ON THE TV I INITIALLY GET GREEN VERTICAL LINES, AFTER IT HAS FOR BEEN ON FOR A FEW MINITUES, THE VERTICAL LINES DISAPPEAR BUT A HORIZONTAL LINE APPEARS...


It sounds like a power surge has damaged the color controller and scan line section of the circuit board. The cost to repair is more then the replacement cost. Next time use a UPS for protection (battery back up for computer and electronics). Regards DaytonComputerDoctor@hotmail.com

Distorted picture when looking through view finder or lcd screen


the video playback is sampled off the video out and independently processed sorta like a TV signal to project on the lcd screen.
horizontal lines means you lost sync circuit and needs troubleshooting. Hopefully maybe a bad connection with a ribbon cable for the ICs and components are hard to change and jammed tight. I would order a video board.

After a household power blips during bad weather, we have horizontal lines ....


Unfortunately there isn't any way to repair your tv as the magnet has distorted the tube that is in the tv and with CRT becoming obsolete the repair is likely to be very costly so probably your chaepest option is to buy a new tv .

Durabrand 21" tv picture distorted


To properly diagnose this problem,access to the servicer menu will be important.Also,the service literature for the horizontal and vertical circuits may be needed.Contact a tech who can help you that is familiar with Durabrand.

Top four inches of screen running horizontal is distorted.


The problem is most likely in the vertical circuit, possibly the vertical IC itself or one of the feeder caps in that circuit. Could be possible poor solder connections on the IC also. Is the problem intermittent? There are a number of common problems with this unit effecting the following parts: Dp027 (27v Zener) P/N 244835 Tp022 (Bc648) P/N 198743 Tp025 (Bc558) Ip001 P/N 257786 Ip050 Ic Voltage Regulator , Zener Diode With 3 Legs Looks Like Diode. Ip030 263567 Dp057 232662 Tp052 198743 Tp020 (2sk2842) P/N 263692 Tp023 (2sc8550) P/N 257827 Dp025 244870 This is an ITC008 chassis built in mexico and the problem you're describing should be an inexpensive repair - but my downside opinion is that with this particular unit you could expect the next problem in about one to two years. Being a certified technician there are few TV's that I would tell a customer to walk away from if they were considering a purchase - but this is one of them. I'm sorry for such a negative review, please don't take it out on my rating for this solution. But if you have it repaired take it in yourself and save a few bucks - and ask the shop to save all the old parts for you. Good Luck Bill

Top section of the picture gets reversed and compressed


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.
