Question about Akai PTH5498 54" Rear Projection HDTV-Ready Television

1 Answer

Blue color Have no blue color in picture. went into convegence service mode 1-8-3 and the blue gun does not show up. Called a TV repair shop was told the crt was known on as he called it "cheap models" to grow algae and wanted $275 + tax to repair if brought in to his shop. Is there any way to fix this cheaper, or do I need to buy a new 1080p tv?

    Forgot to state that the blue does show up on convergence menu 1-8-3 but is very fuzzy and the grid cannot be seen.

TV rca hd 52w59 has convex picture. can I fix it.


If convergence adjustment did not correct the problem likely the convergence IC's have failed and will need to be replaced along with a few defective resistors in that circuit. If you have never attempted TV repair this would not be a good repair to start on.

The only way to be positive of the problem is to have the circuitry diagnosed by someone with the proper TV test EQUIPMENT to determine what parts that are no longer within specs.

How do I adjust the manual convergence? I am in the settings, but my TV is not letting me adjust anything. I chose the "reset to factory" choice, but that didn't fix the red/green shadows


Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.

My TV color has yellow, blue and red shadows n the picture.


Enter Service mode.. Press Menu -0-1-5-7 in quick succession . From there select the convergence option. You should see 3 crosshairs -Red, Blue and Green. Green is fixed but Red and blue can be moved. Align both of them with green and see if the issue resolves. If not Try moving them around and see if the problem is cleared. If not you may have the inevitable convegence IC problem and the IC needs to be replaced. Let me know if that is the case and I will give you the procedure.

TOshiba 36A41 CRTTV has a color problem, i can not see the color Blue.


If it got like that gradually suspect a low emission condition on the Blue gun inside the picture tube, this condition can sometimes be fixed by running a gun cleaning procedure, this is done with a crt analyser device at a repair shop. The other cause for a no blue picture could be a Blue color output that has stopped working, the loss of blue is suddendly when the color out fails, it could also be a problem in the signalprocesing circuit. I suggest having it checked by a tech because it would be something you could not check, first because of lack of equippment and second, you would need some technical troubleshooting skills to do the job.
