Check the deflection yoke connection cable for any loose contact at its connection socket at main board side. Unplug the connector out from the socket, and re-plug it back for at least tow times. Check the solder terminals of all connections to horizontal output. It will be best to re-solder all suspected solder terminals there. [horizontal sweep signals to the deflection yoke is absent now. Only vertical sweep is present now]
Hello.Theres a loose connection in your CRT board of your television.The problem is in vertical section maybe the vertical output IC is cold solder.Thats why harizontal lines appear in the screen of your TV.Your picture is good the problem is in the CRT board at the vertical section.
Hello.The horizontal Line at the center of screen is a vertical problem of your television.The problem is in vertical section of board.Maybe it is loose connection of the vertical outpot.I suggest to resolder the vertical section of the board located at the center part.
1. Plug the stereo audio cable into the headphone jack of your audio source (e.g., stereo, TV, CD player, DVD, etc.). If your audio source has two RCA output jacks instead of a headphone jack, use the supplied Y cable to connect your headphones to the two (red and white) RCA jacks. 2. Connect the other end of the stereo audio cable to the AUDIO IN socket at the back of the recharging cradle/transmitter. 3. Connect the AC/DC main power adapter to the DC IN power supply socket at the back of the recharging cradle/transmitter. Then, connect the adapter to an electrical outlet. Important: This power unit is intended to be correctly oriented in a vertical or floor mount position.
hi first of all u should check ur transistor connections.Check your Horizontal and vertical output transistors.You should also check the horizontal and vertical yoke connections as well as your low voltage regulators.... if any of these got damaged u should purchase a new one.. but try to purchase with the help of a tv service assistant... thank u!!! rate me
If you are comfortable working inside the set and can solder, try resoldering both the vertical IC and the input jack connections. The vertical IC will be a small flat IC attached to a heatsink with about 9-11 pins. It will be marked LA7837 or something similar.
If you have red, white and yellow on each match those and use a cable with 3 strands - red, yellow and white ends with RCA jacks. Use the setup key to get an onscreen display to set options. Make sure they are the video/audio OUT on the DVD not in.
On your TV it's probably Video 1 or something like that - you can usually test this by putting the cables into the front of the TV. The TV remote might have some key like TV/Video to get to the Video input screen. Make sure you check the video-in ports on the TV - not the video/audio-out.
Option if red is missing
If the DVD player just has yellow and white then just connect yellow and white (it will be mono) on the TV.
It shouldn't matter if the holes are vertical or horizontal.
If both TV and DVD have S-video ports then connect those - they will give you better video than the yellow.
You will still need to connect red and white sound cables.
Are the wavy lines horizontal or vertical? If they are horizontal and up near the top of the screen it could be 60HZ interference from a power cord running over the cable from the DVD player to the TV. There could also an internal breakdown of the shielding by the power supply of the DVD player. If the lines are vertical it is likely the cable or maybe the input jack on the TV. Could be a number of things.
If your tv has line out jacks, run cables to the "play" jacks in the back of the 300. If your running satelite, run the sound cables to the player instead of the tv. If your running a vcr player seperate, you can run those sound cable to the back ot the 300. The video cable would go straight to the tv.
