What should i do is my LG 42LC2RR's stand by light keeps blinking but it does turn on

Switch off TV manually, switch off power, remove plug and retry after 48 hours.

If problem persists, please refer it to a qualified service technician.

Tv wont come on and a red light is blinking. I have a Sony Wide screen projection TV model kp-46wt520

Can you unplug the TV for about 15 seconds, and then plug back in and watch the stand-by light. Tell me how many time the stand-by light blinks in regular intervals. If it doesn't blink at all, you need to change a fuse on the g-board. Once this is done run back through the stand-by blink light process, and more troubleshooting can be done if problem isn't already solved. If the stand-by light just keeps blinking with a count over ten just tell me, and I'll look for other possibilities.

Anything less than 5 blinks is major trouble. More likely vertical IC and circuit failure. Picture has been muted or turned off by TV. If Stand By light was blinking 5 times the Stand By might have came out self-diagnosis function or mode.
Contact Sony Service Tech for service adjustment to fix problem.

Changed the lamp and the lamp light came back on. A week later i tried to turn tv on and the status light keeps blinking,and tv will not come on. What can i do to repair myself?

There's a possibility that you might have a defective ballast, or another component form the light engine system, for a better deduction of what might be the issue, discountdasmerchantdotcom the troubleshooting is free

Sony shuts off after being turned on, stand by/timer light blinks

The blinking should be in a pattern of a count, pause, count. That is an indication of the problem circuit. Can you post that count please? That info will allow me to give you possible defective parts and costs for the repair.

Service light

valves and did an oil change myself. I took it in for the 600 service and they charged me a grip so now ill do everything myself this isn't my first bike so don't worry fellas I'm a pretty good hands on mechanic but new to a service/maintenance light on a motorcycle. One thing that is not completed is that the maintenance light is blinking and its annoying so I need to get that to reset but before I go to the dealership I want to know if there's a way where I could reset it for future services? I tried to search but nothing came up unless I'm not searching correctly. Please all help is appreciated TIA!On the SBK's there is no way to reset the light yourself, unfortunately. As for the blinking, it will stop here before long and stay on steady. Don't remember the actual mileage when it stops blinking but it's not long. The indicator does nothing and has zero effect when on so...Mine's been on for 2,000+ miles now. Not gonna drive 90 miles to my dealer just to turn out the wrench.,,,

Sony Television

In these sets, it is common that the flyback transformer assembly, and sometimes the horizontal output transistor. With this there may be some failed capacitors in the horizontal section. When this type of failure occures it is possible that the power supply has some parts that also must be changed. The exact parts will be determined by the way the failure occured.

In some cases the CRT also goes shorted inside of the electron-gun. In this case the CRT must also be replaced.

In short order, you should take the set in for an estimate. It may be on the expensive side to service. If you are lucky, only the flyback may need replacement or some other simple part that is putting the set in to the protect mode.

No picture blinking stand by light

I hve worked on a number of these units , your description is typical of a shorted blue picture tube. The protection circuits in the tv detect that there is a problem thus shutting the unit down to prevent further damage. Sony had a bad run of picture tubes in this series. The replacement cost of the tube is about $250 plus labor. My estimate would be for the repair about $400-500 depending on where you live and how honest your local technican is. I will caution you however, that you could replace this tube and the red or green could go. These would not be covered by the technicians warranty. When these sets are working, they have a superb picture and it is easy to get lured into fixing them. Scrivitron
