Led blinks 7 no video
SOURCE: TV not working
the symptom is usually caused by a breakdown in the power supply circuit. in most modern receivers (transistorized and/or ic), it may also be caused by a breakdown in the horizontal deflection circuits (hor. oscillator, pre-drive, or drive circuits). supply voltages for the tuner, video if,sound if, and vertical output are usually supplied by the horizontal output circuit. but if you doesnt know anything about these stuffs, better bring it to a qualified service tecnhician.

The 2 blinks usually mea an over current problem. Perhaps the most common cause of this is a shortde Horizontal Output Transistor (HOT). If you can solder, you should be able to repair this yourself. Realize that there are potentially dangerous high voltages present inside the set even when unplugged. Look for a 3-legged ransistor attached to a heatsink close to the flyback (part with large red wire coming out the top). The part will be marked C5438 or something similar. Post that marking here nad I'll confirm the entire part number.
Keep us posted.

This means one of three things, either the lamp is bad on your tv, the ballast that powers the lamp is bad or the safety switch for the lamp door is not depressed or it has come un-plugged. It could also mean the power supply or fuse on the power board is blown. I am assuming this is a DLP tv, and if so, it is fairly easy to fix it or find parts for it online. If you are slightly mechanically inclined, want to save money and dont mind paying attention to detail then you can fix it yourself. If you need help dont hesitate to ask.

HI, this is the result of an unstable power sector in this unit. the fly back is malfunctioning and, you will need to replace it asap. i will list the part number below and a link to a site as well. you can purchase this part on-line if you wish.

those LED flashhing codeds are useless. You most likely have a problem in the high voltage circuits. You should bring that one to a local shop as it's very nlikely you can fix it yourself, and the high voltage circuits are dangerous.
