Standby / Timer light with no picture
There are a series of cap and transistors that need to be changed, so if you are not familiar with soldering and component replacement then you may have to have someone do this for you.
I have unplugged because of smell and i
It sounds that there is some arcing takes place inside it. High voltage arcing will produce and Ozone smell. Contact any TV technician. Never use this set at this condition. It might lead to more fault to internal circuit components.
I have a sony tv
If the screen does the same thing with all sources (TV,VCR,DVD), then it is most likely the main control board. The cost to fix or replace it would be more than the cost of a new tv.
I have a Sony tv
Your TV has something shorted inside, and is not a direct short. If it was a direct short, the fuse have been blown. Through my experience I advise you to replace the Picture Tube base socket, which can be located at the picture tube base card. Some CRT base cards will poise this type of problem. as their contacts will worn out with time.
TV comes on but after a while there becomes a
yes. has a pincushion circuit problem. since tv works and then starts to bow, its a bad solder connection. when tv warms up the metal expands and looses connection. when cold, the solder constricts and unit works fine. just solder deflection area. you can probably tap on board and locally find area to solder.
Sony KV-32S40 CRT Television
Read below and decide if you want to tackle the problem yourself if so I’ll help along the way with what info I have. If not contact the nearest repair shop armed with the info below.
A dead set (no picture no sound) can indicate any number of problems – Usually the set is in shutdown or protection mode – this means that the internal circuits have detected a problem with a supply voltage missing, drawing too much current, going over voltage or a short condition.
The first thing to do is power off the set unplug it for 5min. than replug and try again. This in effect resets the main micro and will sometime unlatch a fault and resume working. There are certain common problems based on the make model – for instance convergence output IC’s(CRT projection TV’s) can cause a dead set symptom in many models. Vertical output IC failure can also cause the same symptom (CRT standard and Projection).
The only way to determine the real cause is :
By an educated guess based on experience or by directly troubleshooting the set – checking fuses, measuring voltages and checking for shorts. Many of the intermittent problems such as, int.(Intermittent) no sound or picture, int. picture shrunken or misshaped. These problems are generally due to cold (bad) solder joints (all TV’s and electronics) that break down under slight temperature changes or vibration and are usually verified by physically tapping the suspected area on the circuit board, or by quickly heating or cooling a suspected component or area ( cold spray and hot air gun). The other main culprit is leaky or dried out capacitors or capacitors that change value depending on temperature. These can sometimes be seen as bulged or leaky and have an acrid odour.
