| 08-07-2005 | | The excessive heat, probably from the output stages is likely due to excess current through the driver transistor pairs on one or more channels. This could be due to excess bias, or leaky transistors, more likely the latter. Remove each driver pair until |
| 09-07-2005 | | There could be a short on the mainboard.
Try to measure if there is a short on e.g. the high voltage transitor.
If not, check the secundairy voltages, to see in what circuit the short is?

| 09-07-2005 | | Can you hear any high voltage, when the TV starts?
if not, try to measure the secundairy voltages, and so check if there are shorted ciruits on the mainboard!

| 10-07-2005 | Sony Trinitron "No can See" | Hey
My Sony Trinitron (year 1994) has no picture, has perfect sound, when I switch channels the number of the station flickers twice on the bottom of the screen, it clicks when I turn it on/off.

What might be the problem? : |
| 10-07-2005 | | Windscreen wiper motors are usually 2 speed anyway, can you switch it to a lower speed? What do you want to do with it? Maybe you could gear it down? |
| 10-07-2005 | | You have two opposing magnetic currents, and may burn out a winding or two. If you just wire them in series the output will also drop as you are lowering the turns ratio.
If you fullwave rectify and filter the 15 vac you will have 15 X 1.414 = 21.21 vol |

| 10-07-2005 | | A transistor takes time to turn on so if you play music into it you will miss the quitt sounds and the music will sound broken. You put a little offset voltage into the base of a transistor so it starts to turn on smoothly and you get your good sound back |

| 10-07-2005 | Sony | This is a common problem with Sonys at about this stage as yours. As the CRT ages, they have a built in circuit which causes IK shutdown when the CRT draws to much beam current. In the early stages, this can usually be corrected by turning up the screen |
| 10-07-2005 | Blaupunkt tv | With you having the speaker too close to the screen you have messed up the purity.The speaker is strongly magnetic and has upset the degauss circuit.The best remedy for this is to use a degaussing wand which will re-balance the magnetic field.a service sh |
| 10-07-2005 | | I would suggest that you switch the tv on for 10 seconds, off for 15 minutes repeatedly until the tube is sufficiently demagnetised by the TV's internal degaussing circuit. If after, say a morning of that, then you will have to use a degaussing wand.

| 10-07-2005 | | Lol, I meant to say:
If after cycling the power for so long that you become insane, and still the problem persists, then you need a degaussing wand. |
