Picture problem the picture clarity is fine but after the set is turned on for a short time(30 sec)the sides of the picture will collapse in towards the center of the screen for a second then return to normal.It repeats this every few seconds.The top and bottom of the screen remain normal when this happens.Could this be a horazontal hold problem that can be fixed with an adjustment or is the problem more serious?

The high temp safety switch could be shorted.

Unplug both the set and a box or receiver if used with the set, remove from power for several minutes and replug all to see if a reboot will help or not.

OLD set, most likely the picture tube has aged and only hope would be if the master screen inside the set is turned up just a little it may function again. If doing that (taking back off) be careful and also look in neck of the picture tube to see if the 3 filaments are faintly lit.

Only chances are no filaments or screen set too low from old age.

If your camera does not have a time lapse setting then you need to do this manually or make a device to trigger the remote control on your camera at predetermined intervals.

Hi,

May I know what is the exact model number of your TV, it is located at the rear cover, manual, and on the receipt. It will help diagnose accurately where the fault came from and confirm the blinking error code.

1. Right click on your Desktop
2. Click properties.
3. Click the Screen Saver tab.
4. Click settings.
5. Move slider under "How often my pictures change" to 30 secs.
6. Click ok and then apply.
7. Select preview to test your new settings.

One of the power supply areas are most likely going intermittent. This can be from cold solder connections on the circuit boards, or from some components failing due to age.

An experienced tech should be able to service your set, but it will be expensive for the time involved. Sometimes these types of faults can be very time consuming to resolve.

Diagnosis: Vertical deflection stopped. Possible causes: +- 15V is not supplied. (D board), IC8003 is faulty. (A board) Symptoms of the problem: TV has entered standby state after horizontal raster, Vertical deflection pulse is stopped, Power line is shorted or power supply is stopped.

Phil, from your description it sounds like your convergence IC`s are about to fail, the intermittent off/on cycle is because as they heat up there drawing too much current, the bowed collapse tells me it`s the vertical convergence IC that`s the culprit. You need to get a tech out asap to fix this or they could short and take out the power supply as well and that`s just mooore money to fix it, hope this answers your question, BMW Rider

you have defective starting capacitor! at the hot side!
