SOURCE: Sony kv35s66: No picture, just sound and red blinking

The most common problem (I have fixed lots) is the Vertical amplifier has developed a loose connection. It probably just needs resoldering. As things expand it makes and looses connection you picture goes in and out. The vertical chip is a large black chip that gets hot, over time it degrades the solder until a connection is damaged. Most newer sets have a protection circuit that senses the lack of height, and shuts down the picture tube to save it. When the picture dropped to a line on older TVs and left that way too long it would burn a line into the face of the picture tube. You then had to have the picture tube replaced along with the vertical amp. it's kinda like a screensaver for your TV.

SOURCE: jvc tv

when both the blue light and red light are blinking it means 1 of 3 things. 1. lamp replacement. This often works everytime for the repair. TIP!!! DO NOT USE ANY OTHER LAMPS OTHER THAN JVC AUTHENTIC LAMPS. ANY OTHERS AND YOU RISK DAMAGING YOUR TV FURTHER. 2. the fans are not working properly or need to be replaced. They need to be cleaned every so often and they will stop working from burn-out if not done so. This repair will cost you less than 100 dollars. 3. The ballasts are defective and need to be replaced. The ballasts themselves run about 150 dollars. I tell you I have fixed this TV more times than I care to count, not to mention the number of lamps I have gone through. The guy at the TV repair place now knows me by name when i come to buy lamps. :(

Hi,
Symptom shows Lamp is weak in result and causing restart of TV again and again. Your TV requires new lamp as per following part number...
A1085447A* LAMP BLOCK ASSY XL-2200U
It is available in Sony Accessories Store for $200 and replacement procedure is written in instruction manual of TV.

Always buy Sony original lamp for TV and avoid aftermarket / cheap lamp for TV safety.

Hello
There are two possibilities for this fault with Sony Projection tVs. The first is with the lamp itself. The second one is with the lamp ballast baord. Replace the lamp ballast board first. Because, it there is any internal winding short in the inverter transformar of the ballast board this type of fault can occur. you have to replace the ballast baord along with the new lamp anyway. Therefore, replace the ballast board first. If this help you, there is no need ot replace the lamp. Picture of the ballast included here for you to compare.

gopakumarg43_36.jpg If replacing the ballast dis not help you, change the lamp too. OK.

You cooould have a bad ballast, but it's probably either that you put the lamp in wrong, or you have a defective lamp though. There's a 33% chance that any of those are the case. Unplug the TV for 30 seconds. Plug it back in. Try turning it on again. Make sure you didn't over tighten the lamp during install. Especially the screw on the side. It should be a tight connection. Send the lamp back and get a new one. Usually they come with a warranty. If the new one doesn't work, it's either the ballast, or the power supply.

Hey i have a panasonic Plasma tv (model: TH-42PW5 ). When i press the button to turn the tv on the green light comes on and stays lit, but there is no picture - the screen is dark. What could this be?


Hello,

The problem is either from the lamp or ballast. Have you ever changed the lamp/bulb of your TV?

When the LED shows green, it means it is a lamp problem.

The ballast helps to ignite the lamp and make it function well. So you might have to replace the ballast also.

Good luck.

Samsung hln617w dlp tv won't turn on. Red temp


Had similar problem. Thought it was the lamp. Examined old lamp but it appeared to be good. Ordered a new one anyway. Changed the lamp but the TV screen would not come on. It would make the usual noise as it was going to come on normally but it would cycle 3 times & then turn off. The LED lights in the front panel would indicate a defective lamp. Then read about the ballast. Changed the ballast & still same problem. Tried starting the TV without the lamp installed & noticed that the color wheel did not spin. Removed old color wheel & discovered it was broken. This appears to be the cause of all of my problems. I wish I new earlier of the test-turn on the TV without the lamp being installed & check to see if the color wheel is spinning. Would have save money on the lamp & ballast.

Replaced Bulb and sill have red lamp light


no you should not feel any click,the lamp plug
slides into the ballast plug in the groves.do not
force it,you could have the plug upside down or
you need to visually see if the ballast plug is
damaged.you may need to replace the ballast if you still are getting a red lamp error on the
front of the tv.

T.v. will not turn on. flahes "lamp" then no picture!


This will have to be narrowed down to a specific problem. I would try the easiest things first. First check the lamp. Is it bad or just starting to go bad or does it just need to be reseated with the ballast? If the ballast flickers when turning on your TV, then you will know it is the lamp that is not working or the ballast may need to be replaced. If that is not the problem next check to see if the color wheel is spinning or broken. If broken, it will need to be replaced. If not spinning it is the DMD board that is bad. The color wheel is plugged into the DMD board. If the DMD board is good it will spin the color wheel, that is what will start your lamp. When you lamp starts, you have your picture.
