After various boards and repairs, I still have problem with my picture, my TV wont take the convergence adjustments done manually and the auto convergence display an error message. TV man says the convergence board is bad. Can I repair the Digital Convergence Board PD0638C on my Toshiba 57h82?

U can't do any grid lines adjustments for this problems,the tv problems it is having are known as a convergence pictures problems,it is dead.The tv have any colors lines like R,G,B mis alignments,tv have any colors shadows pictures or have a 3D pictures look alike?Yes,than the tv convergence board it is dead for the tv to causes all of these convergence pictures problems.The tv convergence board must have to be repair like replacing 2 STK convergence ICS and some or all of it resistors too.To fixed the tv convergence board to solved the tv convergence pictures problems.The tvs shops will cost like $300-350 for parts and labors.

(2) (3) (4)
(5) Stretched Image at top and bottom edge very distorted. Reheat all the surface mount solder points on the Small Signal Board. Then realign the set including convergence menu. To enter service mode: power off the set for 10 sec, then hold down Vol- and Ch- buttons for 10 sec. See this link: Alignment Procedure (pdf)


Also download the Alignment procedure pdf file. Hope this will help you. Please let me know if the information was of any help to you or you need further assistance.

Thanks

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.

Not able to do auto or manual convergence adjustment.The tv convergence board is dead.The tv convergence board,must be replacing 2 STK convergence ICS and some or all of it resistors too.To fix the convergence board to solved the tv picture convergence problems.The shop,will cost u like $300-$350

Tries tv auto or manual convergence adjustment,see if that solved this problems.If still have the same problems.That mean ur tv have a dead convergence board.Tv have R,G,B colors lines mis alignments,have colors shadows pictures or 3D pictures look alike?The tv convergence board is dead,must require replacing 2 STK convergence ICS and some or all of it resistors too.To fix the tv convergence board to solved the tv picture convergence problems.The shop,will cost like $300-$350 for parts and labors.

This is a common problem on many brands of Projection Tv sets. Its usually a convergence issue. You can get more details and a solution here on fixya using this link http://www.fixya.com/support/r11932741-convergence_repair_dull_video_repair

PT-47WX53 - Visible Convergence Fault

You need to open the TV. Remove the deflection printed circuit board, access and replace the convergence ICs. Maybe some low ohm resistors are burnt as well. Change those too.

Make sure you do not do any damage to the connections or foil on the printed circuit board. Don't crack the board while breaking loose the ICs.

Also be careful to re-connect all the plugs and the inter-connects between the boards. Don't damage the plugs or connectors. Make sure you put them all back in the correct sockets.

After replacing everything and re-assembling, turn-on and stand back. Look for smoke. If no smoke, look at the picture and see how you have done. Use the auto-convergence if it is available auto-convergence should adjust the convergence grid to an acceptable level. Usually minor touch-up of user's manual convergence adjust screen is all you need to get a good picture. If the customer controls or auto-focus do not work correctly, you have not completed repair.

Do not attempt accessing and fiddling with the service screen unless it is absolutely required.

If there are still problems, get professional service help. Many of the ICs sold by the discount "Shopping Cart" One Stop Kit sites are bogus. They do not work.

Many times consumers buy the New and Improved" IC kits that are offered. Don't even think about it. All low ohm resistors will have to be changed. Many opportunities for damage and misadventure. Your Upgrade kit supplier is re-designing the TV that Panasonic spent millions of dollars perfecting.

Many consumers try to do a convergence repair and TVs become scrap. Check out the TV help blogs, most start with "I installed a set of ICs I purchased on the web, changed resistors as well, Now the TV has a poorer picture than before or it will not start."

If you have no electronics experience or training the chances of success are similar to do-it-yourself brain surgery in a Peruvian jungle with a sharpened arrowhead.

Call local service that knows your Panasonic TV. Ask for price before he comes out. If he won't give a firm estimate for on-site "convergence" repair, call someone else.

Call me in Canada, I'll give you a price.

Hi. your convergence board is failing. this board regulates the the alignment procedure and , the chip set is damaged. replace the convergence board soon.

The auto convergence should run automatically when activated, If it doesnt you will need to replace the convergence board.
