I have a hitachi 57g500 projection tv that we bought in 2003. a hitachi tech came out today to diagnose the problem. he said we have an unusual problem with the tv in that the vertical board was probably bad and the best he could suggest was to have someone come to the house and pick up the tv to take to the shop for $450.00 and the estimated repair would be $500 - $650, if that were the exact problem and there wasn't 4 or 5 other possible things wrong with it. i feel we're being ripped off with the pick up charge. any suggestions on how we might be able to fix it ourselves or get it done less expensive??
when the tv broke, the vertical started flipping about half way through the screen, and the screen became darker and then just finally went black. there is no picture on the tv at all.

Most likely this set has bad convergence amp ic's and some open resistors. This can be a very tricky repair.
resistors RK42, RK46,
RK50, RK54, RK58, RK62
Output STKs IK04, IK05.
Hopefully this will help. Thanks for using fixya.
Ur DM power board is dead.Have burns capacitors,check for puff up capacitors.Buy capacitors parts for replacement to rebuild board.Tries thes websites.Tv Repair World.com Shopjimmy.com Ebay.com or Partstore.com.
i would not repair unless you also replace any circxuit boards that the liquid fell on. although it is now water it will corrode the parts & will most likely cause further problems. the only way to ensure that future problems are not related to this is to replace the boards affected.
