5 yr old tv goes through cycle and tries to come on, eventually does but after many tries.

That model is famous for the Digital board and analog board having issues. The analog board is most likley of the two

the best thing to first is to replace lamp ..lamp will also cause this..this will be the cheapest route to go first..Please let me kno and I will give you more info or docs from Sony...

replace the RED CRT. You can get a replacement Red CRT from www.tvrepairworld.com cost around 100.00

I have the same problem.

when yellow led....push the "P-" button about 5 times then push the left hand square button (looks like square with arrow pointing right) several times until it cycles to the input device.... order is ext1, ext2, ext3, front input, TV....

Sounds like the TV either failed or was thrown out of alignment during the trip to your place.

See if there is a reset button on the remote, or if there is a reset procedure for the television.

I hope you didn't pay too much for a 7 year old TV. Good luck.

When I try to turn the tv on, the green light flashes and eventually goes back to red. A very faint picture came across the tv a few times but didn't stay. The tv is only 3.5 years old.

is this a rear projection tv? a table top one? how old is it because if it's over a few years old, then it sounds as if the bulb may be going out but without having more info, it's hard to give an accurate advice.. please let me know if this helps..

I have a 2 year old Mitsubishi Rear Projection 52" model WD-52525. I recently experienced the same problem as you. My TV quit without any warning and the red lamp light came on. I bought a replacement lamp just like you did, did everything you did too, but it still didn't work either. Since it's past the 1 yr warranty (of course), I took it in to an authorized service center for an estimate. They determined the light engine failed and it will cost me $816.35 to repair. I already shelled out $240+ for a lamp, $48 for the repair estimate and I said "hell" no, I'm not going to fix it for another $800+ and bought a new TV. I'm writing a letter to Mitsubishi expressing my deep dissatisfaction (to put it mildly) with this faulty product and will be requesting reimbursement, which I probably won't get. I sincerely hope this is not the same problem your TV has, but if it is be prepared for a costly fix.

yes you have dust in your optical block may have to be replaced
