Question about Sony KP-53HS30 53" Rear Projection HDTV-Ready Television

2 Answers

Will not turn on.

When you hit the power, the two relays quickly latch then unlatch, and at the same time, the stand by light flashes 3 long and 7 short flashes. It only flashes 3-7 once, but then it flashes 6 times. The 6 is repeated for as long as the supply is there. I have replaced a cap that appeared to be going out to no avail.

7 blinks- horz deflect stopped Q8035, Q8038 Hout
6 blinks- 5v line missing or shorted

I have sony lcd hd ready 50inch rear projector tv model number KDF-E50A12U tv comes on after couple minuets tv clicks off to stand by then red light in stand by flashs 3 times gos back to green repets

Three blinks of standby light to Sony TVs indicates that the regulated voltage output from power regulator board is above thatn normal. The problem is with its power supply regulator board. Replace all the electrolytic cpacitors on that board with new ones. Replace all of them including small and large ones, at one time. OK.

I replaced the bulb because it was broken now when i put the new one in the the power stand by light blinks 3 times repeatly and then goes solid red

Did you just replace the bulb or yjr whole lamp assembly? There is only one correct way to put it together in a new housing. If it's wrong, it will not work. Also, make sure the safety latch on the lamp door is back on securely as well.
Three flashes is Lamp door not detected. Hope this helps

When i try to turn it on the power button flashes a code. The power button lights up once for a second, then turns off, then flashes quickly nine times and lights up once again for a second before turning off. The screen doesnt turn on at all, nor do the speakers. Any help would be highly appreciated.

I own a Sony T.V. model #KV36HS510, Serial # 9024184,Event# E36002407 and it"s aTrinitron brand name. Like the problems before no picture or sound, stand by light on front of unit flashes. When trying to turn it back on you can hear the power click, like it wants to turn on, but does not.
