Best Projection TVs

The lamp light is blinking yellow and it wont turn on.What is wrong?

I have an old(ish) Sony rear projection TV. I think it’s a 32″ model, number KPW41MN11. Recently it’s started ‘flickering’ when I turn it on, and tonight it started actually ‘flashing’, by which I mean the picture sort of ‘pulses’ on and off at a rate of about one ‘flash’ per second.

I’ve opened her up and it seems like the red and green ‘lamps’ (I don’t know if that’s what they are, forgive my ignorance!) are flashing this way but the blue seems to be fine. It’s quite an old TV and was given to me for free, but I’d still like to try and repair it if at all possible. It’s probably not worth the cost of new lamps (I hear they can be quite expensive) but if the lamps are just ‘flashing’ rather than not functioning at all then I figured maybe it’s just a dodgy capacitor or something on one of the boards?

If anyone has any insight please let me know. As I say, it’s an old(ish) unit (as in maybe 10 years?) but I’d like to know if it’s likely to cost more than its’ worth to fix.

We got this for free because it wouldn’t turn on…replaced a fuse and now it works but the blue red and green are misaligned like….rainbow colored letters….? and there are blue and red blended into purple arch at the bottom of the screen.

Convergence boards and lamps always break and need replacing but the real problem is price of those components. They intentionally want you to buy from one manufacturer at hyper inflated prices. Most people are dumping their projection TV’s that may have a glitch then fix them.

Biggest scam.
Convergence boards and lamps always break and need replacing but the real problem is price of those components. They intentionally want you to buy from one manufacturer at hyper inflated prices. It’s kind of what the razor blade companies do. It’s called lock-in. Most of these parts are built so they fit only ‘their’ brand. Therefore the high prices – ZERO COMPETITION in parts. Most people are dumping their projection TV’s that may have a glitch then fix them.

The Lamp is not lighting, there is no indication of audio. The front panel LEDs, Lamp, Status and Pwr act as if the unit goes straight to power saver standby mode with the pwr LED blinking fast as soon as its plugged in. Pressing the power button does nothing, pressing the reset appears to run it through the same routine as plugging it in. At least it sounds that way.
I purchased a service manual and to trouble shoot I’ve done the following:
Verified the power supply that supplies the 370 Vdc to the lamp power board present at the correct point.
Exchanged the lamp with a supposed good one. When the lamp was removed I did get the correct “defective lamp” indication at the lamp LED.
The svc manl says that if the 370 Vdc is is present going into the ‘lamp-sub-board’ and the lamp does not light to replace the board. My questions:
Is the “lamp-sub-board” dumb board? Meaning just put power to the input terminals and it fires the lamp?

My boyfriend is thinking of selling his. He is at work and asked me how much I think it was worth. It works great…so I figured I would ask.

I have a Magnaox 55″ TV projection screen and it shows double picture. I was wondering how do I fix the picture, if I have picture(the green and blue work together and the red picture acts as though it is doubling). PLEASE HELP me.

I have a JVC HD-Z56RX5 TV. The bulb is out and I am looking for a replacement lamp online. The bulb model in the instruction manual is TS-CL110C. When I search this online I only find TS-CL110UAA. Is this model compatible?
