Ws55809 tv picture bows at top and bottom. Also has shadows. Is it the bulb and where do I get one.


You have a convergence problem. The 3 picture tubes are fine. The small signal module needs reworked. The board with all the rca jacks.

TV has alittle dark haze,not bad,9inchs in from side,top to Bott


Probably 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 ebay2_bing.gif 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?)

Tv screen is squeezed only straightens out if i bump the top of tv


This is likely your convergence IC solder connections. Does it look bowed and rainbow colored? The red, green, and blue will be mis-aligned causing a shadow effect. If you can bump it then the ICs (chips) are still ok, it just needs resoldering.

Replace convergence IC's--then re-check convergence alignment in servicer mode,if necessary.
