RCA HD61LPW42YX2 TV has a triangular shadow in the upper left corner of screen, it has become larger over the past 3 weeks. I've read that other people have had this problem. Is it a color wheel problem or is it the light engine. I've contacted some repair shops and was told that the light engine was unavailable. I hope you can help, or anyone else who has resolved this same problem.

Problem #1) Convergence

• No Audio/Video - TV makes a chirping sound.

Problem #2 CRT Fluid has clouded over. Symtoms

someone is going to have to look inside by either removing the rear upper part of the set or removing the entire front screen---neither is easy to do. But considering your trouble I would not be surprised if the mirror is cracked---the entire front screens would have to be removed to replace the mirror--special mirror and special handling--I have seen several break when someone is not careful putting in.

I would check for dust particles before I attempted any type of repair on the unit.

Dust particles will appear as dark spots that are larger than the size of an individual pixel. It must first be determined if the particle(s) are on the LCD panels or the screen.

your tv needs to be swithed frm av to tv from its remote.if you dont have a remote buy a universal that will work with this brand,read universal code list before buying!!!

It's the light tunnel. The tunnel is a square tube made up of 4 mirrors glued together.

It looks like this from the side: |_| (with a piece on top too.)
When the glue breaks down, it shifts inside the little mirror holder. The shifted mirrors looks like this /_/ what you are seeing is the shadow of the tilted mirror tunnel.
ON the RCA's there's not a good fix.

RCA's response:
"Ok, well sadly they do not offer the light tunnel anymore, which is what you need. Sadly you would be rendered to get a whole new light engine assembly. That would be the D.N.D module, light tunnel,color wheel,optic spanner, and oci. mirror. Your best bet would be to search ebay for a broken engine and replace it that ways."

That is the ONLY response I got from them.

I took the set apart and found the 4 tiny mirrors. I will be attempting to epoxy them together. (The set is dead anyway, why not try?)

sound if u might have what is called a crt burn

If you have the extended warranty, use it immediately. This happened with ours after our 1 year warranty expired and found out it would cost us over $1000 to have it fixed. We've read that RCA used faulty glue that can't withstand the heat inside, causing a mirror to slowly slip over time. Our dark shadow keeps growing and growing.

RCA should have recalled this to fix it for everyone.

You may have a dirty or blocked mirror. You can usually take the back off and clean them. If you don't feel confident about it, a repairman can do it for you. If you clean it yourself, I recommend using a good quality glass cleaner and any type of towel that doesn't produce lint. Coffee filters work very well. Don't leave any streaks!

if u are not a technician, better have it check by a qualified one. because doing so might create more problems. service center have special tools and equipment for aligning and replacing these stuffs. just concern

sounds like your main power supplyis going bad . It supose to be 130 dc but I'll bet its down to around 90 to 100 volts!!! its probably the main filter cap or the regulator IC . hard to say without measureing the b+ good luck
