If this is a rear projection tv, there should be several phillp head screws that need to come out. If its a rear screen projetor with a projector lamp the lamp can be pulled out of a side door to clean it off.

Sony KDS R60XBR1 red light blinking 3 times. Replaced lamp, cleaned all vents, replaced cover door properly.. What else?

You may need to take off the back cover and clean the fan and if you can, put a little oil on the fan shaft. I also use a small vacuum to get more of the dust out around the fan. You can blow out some of the dust but be careful as you don't want to blow dust into the lamp area. When you take off the back cover you'll be amazed at the amount of dust in there!

Replaced bulb on 50 inch sony rear projection tv. picture came on for about 5 min then shuts off and power button blinks red

Did you clean out the lamp ventilation duct in the back of the set? If it's clogged with dust you could have an overheating problem (this also kills lamps). You may need to unplug the set and remove the back cover to make sure you can evict all of the dust bunnies in the duct. Also, vacuum out all of the vent slots in the back cover. Try not to get any dust into the bulb or optics.

Safety notes: the set should have been off for at least 30 minutes before doing anything to avoid getting burned on the lamp. Do not touch the electronic circuit board, even if it is dusty (just use your breath to blow the worst of the dust off the circuitry). Touching the circuit board or using a vacuum cleaner on it can cause damage by static electricity charging. There is also a possibility of getting an electric shock from capacitors still holding a charge. Normally, this stuff is nowhere near the lamp ventilation hardware, so it should not be a problem avoiding it. But definitely make sure you unplug the set before doing any of this.

If this doesn't fix it, repost and we'll look for the more arcane answers.

My Sony grand wega turns off and on and the stand by light blinks off and on untill the tv picture and sound comes back what is wrong? The book says something about three blinks but its not three it is...

I don't have the service manual for this, but I suspect something is overheating, possibly the lamp. Try cleaning out the vents. If you find a lot of dust, unplug the set (note: if you have just tried to run the set, wait for the fan to stop running, unplug and wait 30 minutes for the lamp to cool), then remove the back and clean out any ductwork going to the lamp assembly. If it's really loaded, remove the lamp assembly and vacuum the dust out of there. Be careful not to touch the optics, and DO NOT touch the lamp itself. Try not to leave any dust on the LCD panel or color wheel; that would show up on the picture.

If you see a lot of dust on the circuitry, blow it off, but don't use air from a compressor. The circuitry is susceptible to damage from static electricity. Fast-moving air from a compressor of vacuum cleaner can generate a harmful charge. Even touching the circuitry could zap it. If you don't want to use your lungs, you can buy aerosol cans of static-safe gas made for this job.

The main thing is to make sure the bulb isn't overheating. A thin layer of dust on the circuit board is not likely the problem. Let me know if this works.

My Hitachi 60v710 HDTV does not come on and when in off position lamp lite is red and when on lamp and led blinks red and power blinks blue what is wrong and can I fix it myself

Did you say the lamp blinks red? I assume you meant the lamp status indicator light. That probably means the lamp is burned out. Take the lamp assembly out and inspect the bulb. If you see a visibly burned capsule or broken wire inside, that's your problem (you don't need to remove the lamp from the assembly to inspect it, and don't touch the lamp itself - see next paragraph). When you replace it, be sure you clean all of the vents in both the front and back of the set. Dust-clogged vents will cause a bulb to burn out prematurely, or even explode. You may need to remove the back cover (unplug first!) to clean out a dust filter for the lamp cooling duct.

You can save money by buying a bare bulb and rewiring it into the lamp housing, but be absolutely careful never to touch the new bulb with bare fingers - the contaminants from your fingertips may cause the bulb to explode when it gets hot. Wear disposable vinyl gloves (the kind restaurant food handlers use) for this job. The gloves may be included with the new bulb.

Set a regular cleaning schedule for the vents. How often depends on how quickly the dust builds up. Just don't let them get completely covered with dust.

Lamp cover melting

Open the back case (about 10 screws) and clean the lamp cooling fan. This is NOT the one you can see from the outside. It is located in a horizontal position above the lamp area from the rear. A DRY toothbrush can be used to brush out the dust. Keep a vacuum nozzle next to it while cleaning so the dust does not go inside. Some say to use compressed air to blow out the dust, but vacuuming it keeps better control and can prevent unwanted dust from moving down into the optics.

I learned this the hard way when replacement lamp burnt out in one week. I thought the cooling fan that you can see from the outside (it actually is the exhaust fan) was the only fan. The lamp cooling fan sucks in cool air and puts it right down onto the lamp.

Test the fans by turning on unit without lamp installed (the fans will power on for a short period of time and you can see them function to verify airflow). Clean this fan once a year as the dust will be back.

Replace lamp led light

Have you reset the lamp timer?
Was the lamp module sitted properly?
Remove the back panel and vacuum all the dust.
Also use compressed air to blow out the dust from the inside.
Do not blow into the fan on the right as that will get the dust inside the lamp housing.

Turning off

Have you replaced the lamp? shut down problems come from several things but the most common is lamp current draw, thermal shut down (fan clogged), and bad ballast .I'd start with the lamp.

Picture & Sound blink off 45 seconds, blink back on, repeats

If the lamp is foggy then you really need to replace it. The lamp life is typically 5 to 7 thousand hours. However if your tv gets a lot of dust inside which is pretty normal as most people don't vacuum the dust off from the rear cover on a regular basis then the lamp life will be drastically reduced. I suggest you replace the lamp and make sure the inside of the tv gets vacummed out to remove as much dust as possible. A Sony servicer should be able to check the amount of hours on your lamp. You'd be suprised how soon 5-7 thousand hours happens. If the lamp will not come on after replacing it the lamp driver may be at fault. You haven't said how may times it's blinking. If it's 5 then the lamp driver may be at fault.
