Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Sony Kv27S66-I'm seeing horizontal lines through the screen the last few days. Checked the cable connection, reset the set-up, but no change. Color is still excellent on the TV, anything I can do or...


You must pull the main board out and re solder the vertical IC. This IC is mounted on a large heat sink. I remember that this vertical IC is of the TDA series. It would have seven pins. The pins will have to be re soldered, please do not use too much solder. You do not want to short the pins with excess solder. Next, you will need to check and replace the capacitors that are near and next to the vertical IC. We are talking about four capacitors, in this area. These caps, when weak, will create those horizontal lines you talk about. Second, the weak cap will cause the vertical IC to over heat and the pins will separate from their perspective grounds. Thanks for asking me, and show all hands of support!

Hey! I'm trying to turn on my Sony Trinitron KV27S66 but it flashes the standby light and doesn't show an image. What is wrong with my TV? What can I do to fix it?


Hey there,

Is it set to the correct input?
There should be a button on the set or on the remote called "input" or "source".

If you're trying to watch tv, make sure it's set to Cable, etc.

Hope this helps!

My Sony Trinitron stand by/timer light is on and will let me put tv on but only stays on for a few seconds . Model #KV27S66 Oct 99


Your TV has an overload due to some faulty components inside it. This type of fault is usually noted with overheating of horizontal output transistor connected to LOT of the TV. This may be due to LOT fault, or fault to the transistor itself. When it overheats, it put a short between supply rail, and the power supply regulator system inside your TV will detect that short and will shut down automaticaly. Please note; if the TV works after some time, say after 15 or 20 minutes; and again shuts down after working for a short period, and the cycle repeats, surely there is a winding short inside LOT, which cannot be detected by normal multimeter measurments. If it is so, replace LOT and the horizontal output transistor at the same time.

Try to turn on my ps3,after 2or3 sec it turns off and just blinks


HI, the power unit is experiencing some difficulties due the an overheating issue. if the light is turning yellow at any time, this will confirm a overheating issue. Now, if the light is simply turning red and, powering off then system with a red blink, this will confirm a power unit failure. you will need to replace the power unit in this case.

Contact your nearest Sony repair shop of, contact Sony manufacture for this repair.

NOTE(If its a simple overheating issue, you can purchase a cooling device to heel this issue)
