Circuit diagrams of many popular brand TVs and other devices are given

Hi Roberta.

its the horizontal circuit fault in the Tv. Look back from the Yoke socket and from the two red and blue terminals and you you will get into the horizontal circuit

uusually its components starts with the number 4 at the Tv chassis

resold the components there good and this problem will be fixed

as its a solding loss or track cut at the tv chassis

you need to be familiar with tv repair to do this or get technician to fo thid for you

not able to play wii on av channel - just comes with blue screen and count down timer? Have connected to the require colour codes on tv

Try using the source button to switch through different inputs.

If that does not work try connecting a signal booster to the aerial, they cost about ten pounds at Argos.

This indicates "vertical stop," meaning that the TV's vertical output circuit is not working. A number of thing can cause this: failure of the vertical output IC or related components; bad solder connections to the vertical output IC (a common problem); power supply trouble keeping the vertical circuit from operating (also a frequent cause). Without having the set available, it's impossible to offer any suggestions for you to attempt repairs beyond looking for bad soldering. Other troubleshooting would require the circuit diagram (often available from the internet), tools and experience working on a live chassis. If you really want to keep the set and don't feel up to self-repair, it might be worth getting an estimate from a shop. These Sonys are nice sets.

Hi
I have a .pdf of the diagram - can you let me know your email so I can send it - it's too big to attach.

This is a problem with the vertical circuit. Look for a small flat IC attached to a heatsink that will be marked LA7837 or something similar. It should have about 11 pins. Try resoldering the pins on that IC first. If that does not resolve the problem, replace the IC. There may be capacitors that require replacement in that circuit as well.

Keep us posted.

The TV is Manufactured by a company called Vestel in Turkey and will operate on the AK45 chassis remote control,if you try the codes for Bush or Alba one will operate it nut not of course menu functions but no problem there is a menu button on the side of the set.
