Sony Trinitron Wega KV-34HS420 blinks 7 times it means the the Horizontal Deflection stopped.
There are two cause for this: B overcurrent is detected (IC5007 is defective) or there is a over heating is detected by the Thermistor (TH5002). Both of these parts are on the DZ Board. If you order the DZ Board from the "Partstore.com" it will cost you $395.95 minimum. The Thermistor TH5002 (part # 1-807-796-11) cost $4.95.
This IC chip IC5007 is no longer available at Partstore.com. You could purchase it from other stores. Not sure of price.
Replacing the whole DZ board would for sure fix this problem but at close to $400.00. Then what if another board or your picture tube goes out soon.
Better to go buy a new flat panel LCD from Costco for around the same price.
Hope this helps

SOURCE: TV wont turn on, sandby light flashes 7 times.

Any malfunction associated with a flashing stand-by light usually indicates a circuit problem or defective component. Unfortunately, the days of taking off the back cover of your TV and replacing a defective tube or fuse are long gone. Proper servicing will require troubleshooting procedures that can only be performed by a qualified electronic repair facility or professional television repair person. Ask for an estimate and a realistic appraisal of whether the set can be adequately fixed. Depending on the age and condition of your TV it may not be cost effective to repair.

Follow the instructions from the image provide and see if that works, if it does not work; you have a hardware failure in your TV. The hardware failure could be the HOT or flyback transformer.

TV will not turn on. I press power and it sounds like it's coming on and then clicks and the stand by light flashes 7 times. Have already tried unplugging and then plugging back in after a minute


When I called a tv repair company the rep said this usually indicates that the "lamp" for this model needs to be replaced. Since he TV is so heavy he suggested that I access the trap door in back of the console and detach the "lamp" myself and bring the lamp to his shop for replacement. Approximate cost for the lamp is $200.00. Wish me luck.
